Diamonds are a part of the ‘big four’, alongside sapphires, rubies and emeralds. These four precious gemstones make up a vast majority of the world’s fine jewelry.Natural diamonds take over a billion years to form, making them the most prized gemstones to be unearthed. In this blog, we will share with you a few of these gemstones that tend to dethrone diamonds as the rarest and most expensive gemstones.
Why are these Rare Gemstones rarer than Diamonds?
As mentioned earlier, quite a few other gemstones are much scarce, and therefore, more valuable and expensive as compared to diamonds. Some of these may fetch a higher price per carat compared to a diamond of the same carat size. This is mostly due to them belonging to mined in specific regions of the world, for example, Tanzanite originates primarily from Tanzania. Other reasons include rare color, as in the case of Paraiba Tourmalines. Some gemstones exhibit special phenomena, such as color changing properties in Alexandrite. Some gemstones may simply overtake diamonds in popularity due to an excellent balance of color, cut, clarity and carat size.
Tanzanite are the rare, purple variety of the mineral Zoisite, which in turn belongs to the Epidote mineral family. Tanzanite, as the name suggests, originates from the small East African country of Tanzania. Not only that, the landscape where the stone is mined is so complex lying at the foothills of Mount Kilimanjaro, which makes it challenging to mine, hence adding to its value. Its intense violet color is considered to be at par with violet-hued sapphires. A majority of light colored specimens of Tanzanite often undergo heat treatment which makes the naturally saturated and good clarity specimens rare and quite expensive.
Alexandrite is a variety of the Chrysoberyl mineral family that has a unique property known as color change. In day light, Alexandrite are a pale to emerald green color, while in incandescent lighting, they exhibit a ruby red to purplish red color. Originally discovered in Russia, this stone was named after Alexander, Czar of Russia due to resembling the colors of the Imperial Russian Court. The chemical composition gives this variety of Chrysoberyl its rarity due to containing traces of chromium alongside iron and titanium, which in turn causes its color change phenomena.
With a vivid blue-green coloration, Paraiba tourmalines are one of the most mesmerizing and rare gemstones discovered.Paraiba tourmalines get their unique neon green and blue coloration due to traces of copper, a rare occurrence in Tourmalines. Primarily mined in the state of Paraiba, Brazil after which they are named, they are coveted due to scarcity of natural deposits.It is believed that there is only one Paraiba tourmaline mined for every 10,000 diamonds. Despite only being discovered in the 1980’s, they are highly prized and fetch a high price per carat.
While Rubies are generally rare and are part of the four precious gemstones that constitute a majority of the world’s most popular gemstones, Burmese rubies are even rarer. Burmese rubies originate from Myanmar, previously known as Burma, hence their name. The reason why these rubies are so rare is due to an absence of iron which usually makes rubies appear more dull or brown-tinged. The geological conditions in Myanmar allow for the production of more vivid, red rubies, popularly known as ‘pigeon’s blood’ rubies.
Kashmir Sapphires, as the name suggests, originate from Kashmir, along the Himalayan range. This velvety blue variety of sapphires has a signature appearance due to natural silk-like inclusions that give them a softer look as well a distinctive coloration as compared to other blue sapphires. Their most prized color is known as ‘cornflower blue’. Their rarity comes as a result of exhausting several of the mining locations wherein they first originated in igneous rocks. As a result of a lower demand to supply ratio, they are rare and command a higher price per carat as compared to a diamond of a similar carat size.
While diamonds are the first choice that comes to mind when thinking of engagement or wedding rings, colored gemstones eventually became equally popular as a result of marketing by many renowned jewelry brands. Not only were diamonds eventually swapped out for fancy colored diamonds, but rare gemstones became the center of attention as a result of being worn in wedding and engagement rings by celebrities and high profile individuals.
