How To Pick The Best Centerpiece Gemstone?

Picking your gemstone can be a stressful process. There is a lot to consider from and if you are like me, it is even more stressful because some of us can the most indecisive person in the world. In this post, we will cover the differences, meaning of all precious stone and give you reasons why you should choose it. Essentially a foolproof way to pick your stone to perfection!

Why is choosing gemstone important?

Your jewelry is not disposable. It will follow you through ups and downs and for many years of your life. It is your companion so when you look at the stone, you will see the marks and the scratches to remind you of a past you love and memorize. To us, it is a keeper of history. It tells a story. It is your friend. You would not want a bad friend or a friend you do not love.

What should I consider when buying a gemstone?

  • Price: not every stone costs the same. Choose the stones within your budget or size down on more expensive stones.
  • Vendor: TIDAN ensures that your stone is 100% authentic and true as description. There are fraudulent vendors that might trick you that a garnet is a ruby and a zircon is a diamond. There are significant differences in hardness, rarity and price. For safety, choose only reputable retailers.
  • Source: opt for ethically produced gemstones. You can play a part in shutting down unethical working conditions and reducing environmental impact.
  • Color: it should be a color that you love and it should complement your skin color.
  • Clarity: it should shine as bright as possible.
  • Cut: the cut decides whether there are surfaces for light to reflect or not. Brilliant cut usually guarantees a reasonably high amount of reflection.
  • Size: the size of the stone is a bold statement on status and prosperity.
  • Hardness: damage to gemstone is not often but it is not easily fixed. Choose stones hardness depends on your lifestyle and you should be good to go!
  • Mystical properties: you can choose stones based on its assigned birth month, zodiacal and special meaning.

This list is ranked from the hardest to the softest on Mohs scale of mineral hardness.

Diamond

Diamond ring from TIDAN

Science: Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form, but diamond almost never converts to it. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are utilized in major industrial applications such as cutting and polishing tools.

Zodiacal: April birthstone.

Symbolism: purpose, initiation, and clarity.

Why should you choose this gemstone?

This is the ultimate classic stone. It is the most popular gemstone on rings nowadays for its unmatched durability and its colorless appearance. This would be a great option if you are looking for something classic, timeless, and long-lasting.

Moissanite

Moissanite ring from TIDAN

Science: Moissanite is naturally occurring silicon carbide and its various crystalline polymorphs. It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893. Silicon carbide is useful for commercial and industrial applications due to its hardness, optical properties, and thermal conductivity. It is also the 2nd hardest stone after diamond.

Can be used interchangeably with diamond as April birthstone.

Symbolism: unbreakable love and romance.

Why should you choose this gemstone?

Moissanite is significantly lower in price compared to a diamond and has similar properties. Moissanite is slowly overtaking diamond in being the best value-for-money stone for jewelry. Moissanite is usually produced in a controlled lab environment that will ensure the least amount of flaw and the maximum shine (Moissanite shines better than a diamond). You also will not have to worry about terrible working conditions with moissanite!

Sapphire

Sapphire ring from TIDAN

Science: Sapphire is a precious gemstone, a variety of the mineral corundum, consisting of aluminum oxide (α-Al2O3) with trace amounts of elements such as iron, titanium, chromium, vanadium, or magnesium. It is typically blue, but natural “fancy” sapphires also occur in yellow, purple, orange, and green colors. It is the 3rd hardest gemstone behind diamond and moissanite. The biggest star sapphire found on Earth is named The Star of Adam and is the size of a palm.

September birthstone.

Zodiacal: Taurus (21 April to 21 May).

Symbolism: Honesty, purity, and trust.

Why should you choose this gemstone?

While a sapphire is not as durable as a diamond or a moissanite, it is still magnificient in its durability and you won’t have any problem with it daily. Its distinctive blue color is an eye-catcher for many. Blue diamonds are rarer and as a result more expensive than sapphire itself. A good trade-off between hardness and color.

Ruby

Ruby necklace

Science: A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminum oxide). Other varieties of gem-quality corundum are called sapphires. Ruby is one of the traditional cardinal gems, together with amethyst, sapphire, emerald, and diamond. The chemical formula of ruby is Al2O3:Cr.

July birthstone

Zodiacal: Capricorn (22 December – 21 January)

Symbolism: courage, life force, and passion.

Why should you choose this gemstone?

Ruby is as hard as a sapphire. There also is not a significant difference in price for both gemstones. All it boils down is what color you love. Red – a sign of fiery passion, love and strength or blue – trust, wisdom and honesty. However, please note that garnets are marketed by dishonest vendors as ruby and you should always buy ruby from certified sources like TIDAN.

Alexandrite

Science: The mineral or gemstone chrysoberyl is an aluminate of beryllium with the formula BeAl2O4.[4][5] The name chrysoberyl is derived from the Greek words χρυσός chrysos and βήρυλλος beryllos, meaning “a gold-white spar”. Despite the similarity of their names, chrysoberyl and beryl are two completely different gemstones, although they both contain beryllium. The three main varieties of chrysoberyl are: ordinary yellow-to-green chrysoberyl, cat’s eye or cymophane, and alexandrite.

June birthstone

Symbolism: intuition, creativity and imagination.

Why should you choose this gemstone?

Alexandrite has one distinctive feature that might impress you. The stone can change color depends on the type of light it is exposed to such as daylight, incandescent light, torchlight etc. Fine-quality alexandrite has a green color in daylight but changes to red in yellow illumination. It is also able to be lab grown making it a good choice for the trendsetter who is not satisfied with one color.

Spinel

Science: Spinel is the magnesium/aluminum member of the larger spinel group of minerals. It has the formula MgAl2O4 in the cubic crystal system. Its name comes from the Latin word “spinella”, which means spine in reference to its pointed crystals.

August birthstone

Symbolism: compassion, protection and optimism

Why should you choose this gemstone?

Spinel has amazing colors. Spinel is one of the few gemstones that require no special treatments. As with many stones above, it boils down to your color of choice and your selection of what it represents. Spinel is super rare however, even the rarer spinel costs less than the ruby. Spinel is so rare that you are lucky to stumble upon a retailer with it.

Topaz

Science: Topaz is a silicate mineral of aluminum and fluorine with the chemical formula Al2SiO4(F,OH)2. Topaz crystallizes in the orthorhombic system, and its crystals are mostly prismatic terminated by pyramidal and other faces. It is one of the hardest naturally occurring minerals (Mohs hardness of 8) and is the hardest of any silicate mineral.

November birthstone

Zodiacal: Sagittarius (22 November – 21 December)

Symbolism: magnification, clarity, and manifestation.

Why should you choose this gemstone?

A little history research will let you know that in ancient Egyptian civilization. The stone was valued highly because of its yellow color, which was believed to be created by the Sun God, Ra himself. Topaz is often chosen for its ability to have a wide range of colors. With topaz, you can have a whole rainbow (Rainbow Topaz)! In our opinion, it is absolutely perfect for the fashionable without having to invest a whole lot. Topaz, however, is only 8 in the scale of Mohs so you will have to take a care of it to avoid fragmentation.

Aquamarine:

Science: Aquamarine (from Latin: aqua marina, “sea water”) is a blue or cyan variety of beryl. It occurs at most localities which yield ordinary beryl. The gem-gravel placer deposits of Sri Lanka contain aquamarine. Green-yellow beryl, such as that occurring in Brazil, is sometimes called chrysolite aquamarine.[13] The deep blue version of aquamarine is called maxixe. Maxixe is commonly found in the country of Madagascar. Its color fades to white when exposed to sunlight or is subjected to heat treatment, though the color returns with irradiation.

March birthstone

Zodiacal: Scorpio (24 October – 21 November)

Symbolism: youth, health, and fidelity.

Why should you choose this gemstone?

They are durable enough for an average lifestyle, they are very unique since most people opt for more popular options such as diamonds, moissanite, rubies, etc. without considering other gemstones. Due to that same reason, aquamarine is usually affordable. Their sea water color is a great fit for people seeking a calm and classy look.

Emerald

Science: Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor.

Zodiacal: Cancer (21 June – 22 July)

Symbolism: love, rebirth, and fertility.

Why should you choose this gemstone?

Emerald have a rich green color that exerts a very royal and very luxurious feeling. It has been a staple in the noble’s wardrobe for thousands of years. This list is ranked from the hardest to softest, therefore it is always better if you pick stones ranked higher. This, however, will last with average daily use.

Tourmaline

Science: Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminum, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gemstone can be found in a wide variety of colors.

Symbolism: joy, love, and emotional healing.

Why should you choose this gemstone?

Tourmaline often comes in all shapes and sizes. You can choose the color, cut and size you want without breaking the bank. It can resemble if not looks better than sapphire, ruby and emerald.

Amethyst

Science: Amethyst is a purple variety of quartz (SiO2) and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions.

Zodiacal: Pisces (19 February – 20 March)

Symbolism: protection, cleansing and healing.

Why should you choose this gemstone?

It is relatively inexpensive for a precious stone since most stones you would find nowadays is not natural but synthetic. If you prefer natural stones, ask for it. Apart from color being a factor, if you believe in psychic abilities of stones, amethyst is very prominent in the community for its amazing psychic assisting abilities.

Citrine

Citrine gemstone

Science: Citrine is a variety of quartz whose color ranges from a pale yellow to brown due to ferric impurities. Natural citrines are rare; most commercial citrines are heat-treated amethysts or smoky quartzes. However, a heat-treated amethyst will have small lines in the crystal, as opposed to a natural citrine’s cloudy or smokey appearance. It is nearly impossible to differentiate between cut citrine and yellow topaz visually, but they differ in hardness.

Symbolism: protection from evil thoughts, success and prosperity.

Why should you choose this gemstone?

Very affordable for such a beautiful stone. It is quite popular for its availability and its price. You will need to care for it frequently or choose a protective piece of jewelry to avoid any damage to the stone. Should you want to elevate your stone to a whole new class. Ask for Ametrine. Ametrine is an extremely rare stone which combines the stunning purple of Amethyst with the invigorating yellow of Citrine. It is a thing of beauty.

Garnet

Science: Garnets are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical properties and crystal forms but differ in chemical composition.

Zodiacal: Aquarius (21 January – 18 February)

Symbolism: healing, protection from nightmare and accidents.

Why should you choose this gemstone?

Garnet is comparable in terms of look to a ruby to the untrained eye. As it is lower in the scale and its not as rare, the price of garnet are often more affordable.

Zircon

Science: Zircon is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate, and its corresponding chemical formula is ZrSiO4.

Symbolism: innovative, honor, prosperity and help with sleep.

Why should you choose this gemstone?

Zircon has been used as a gemstone for over 2000 years. Its very high dispersion and refractive index give it a brilliance and fire that rival those of diamond. For that reason, colorless faceted zircon has been used as both a popular and fraudulent substitute for diamond.

Peridot

Peridot necklace

Science: Peridot (sometimes called chrysolite) is gem-quality olivine and a silicate mineral with the formula of (Mg, Fe)2SiO4. As peridot is a magnesium-rich variety of olivine (forsterite), the formula approaches Mg2SiO4. Its green color is dependent on the iron contents within the structure of the gem.

Zodiacal: Libra (23 September – 23 October)

Symbolism: creation, healing and abundance.

Why should you choose this gemstone?

Peridots are seldom subjected to treatments as most of them do not have eye-visible inclusions. So expect brilliant clarity and a vibrant color from an heirloom quality gem. Peridot is considerably inexpensive (even if you opt for a three or four carat stone). It is therefore a great buy if you have a limited budget and want to enjoy a pop of fresh and vivid color.

Onyx

Science: Onyx primarily refers to the parallel banded variety of the silicate mineral chalcedony. Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands: agate has curved bands and onyx has parallel bands. The colors of its bands range from black to almost every color.

Zodiacal: Leo (23 July – 22 August)

Symbolism: stamina, persistence and optimism.

Why should you choose this gemstone?

Onyx stones are timeless and versatile gemstones. The black hue can look elegant and sophisticated, yet it can go well with all outfit and any occasion. With all the fast fashion trends going on, keeping up with trends can be tiring. With a few onyx ring or onyx jewelry in your jewelry box, you can never go wrong! Please note that stones from this down can chip and crack very easily without sufficient protective measures. We highly recommend harder stones for better durability and peace of mind.

Tanzanite

Science: Tanzanite is the blue and violet variety of the mineral zoisite (a calcium aluminum hydroxyl sorosilicate), caused by small amounts of vanadium, belonging to the epidote group. Tanzanite is only found in Tanzania, in a very small mining area (approximately 7 km (4.3 mi) long and 2 km (1.2 mi) wide) near the Mirerani Hills.

Symbolism: wholeness, integration of heart and mind.

Why should you choose this gemstone?

Tanzanite is a gem that many people desire because of its unique beauty and characteristics. Others purchase tanzanite because it has a beauty similar to sapphire but at a much lower price. Tanzanite also competes with lab-created sapphires that are lower in price than natural sapphires. Tanzanite is very rare. In fact, we might be the last generation that might own Tanzanite firsthand. It’s this rarity that makes Tanzanite a good investment as demand is growing, but the supply is limited. Expect the value of this rare blue gemstone to increase in the coming years.

Agate

A picture of agate earrings
Agate earrings

Science: Agate is a common rock formation, consisting of chalcedony and quartz as its primary components,[1] consisting of a wide variety of colors. Agates are primarily formed within volcanic and metamorphic rocks. Decorative uses of agates date back as far as Ancient Greece and are used most as decorations or jewelry.

Zodiacal: Gemini (22 May – 21 June)

Symbolism: composure, maturity, soothing.

Why should you choose this gemstone?

Because of the way it is formed, each piece of agate is different from the other, making the stone you buy distinctly yours. This is one main reason that makes agate so perfect for jewelry. No one else will have an identical piece, making yours unique. Agate is one of the oldest gemstones used in jewelry. In fact, small agate beads have been found in the Middle East and are thought to be approximately 9000 years old! Agate must look a certain way to be classified as gemstone.

Carnelian

Science: Carnelian (also spelled cornelian) is a brownish-red mineral commonly used as a semi-precious gemstone. Similar to carnelian is sard, which is generally harder and darker (the difference is not rigidly defined, and the two names are often used interchangeably). Both carnelian and sard are varieties of the silica mineral chalcedony colored by impurities of iron oxide.

Zodiacal: Virgo (23 August – 22 September)

Symbolism: vitality, motivation and creativity.

Why should you choose this gemstone?

As with other opaque silica gemstones, carnelian jewelry is quite affordable making it ideal for daily jewelry pieces. It adds a burst of color to any outfit and tends to stand out beautifully against any skin tone. Carnelian looks beautiful in both silver-hued and yellow gold metals. When set in yellow gold, carnelian takes on a vintage charm as the two colors complement each other perfectly. However, silver metals accentuate the color of the stone and adds the perfect contrast.

Conclusion

All stones have its unique beauty, function and style. No one can give a definitely answer which stone is the best because each person is different. If you have a very active lifestyle, choose a diamond, a moissanite , a ruby or a sapphire. You want to look great without breaking the bank? Choose less hard stones that will not cost a fortune. You want a heirloom that will pass on to generations? Choose the hardest stones. You like green? Choose peridots or emeralds. The possibility is endless!
