Rare gemstones


We can typically estimate a gemstone's value with the help of 3 key factors: rarity, size, and quality. It's especially rarity which plays a significant role in the price of natural gemstones. Of course, rare stones are often also lesser-known too. That's why we thought to create a short guide representing some of the rarest, hippest and most alluring gemstones on the jewelry market.

Black Spinel:

Fully black gemstones are always a rare find. Spinel is a crystal that comes in naturally sharp formations and occurs in diverse colors. Black Spinel Stone is one of the rarest occurrences of spinel, therefore, it has a high value. What makes black spinel so outstanding is being much more translucent and reflective than other crystals. Being hard and durable, black spinel is the perfect choice to wear in a ring on a daily basis.

Alexandrite:

Alexandrite is a real rarity and it’s a young gemstone, being identified less than 70 years ago. Alexandrite is one of the very few natural gemstones that have color-changing attributes. It can look green but it can also look red, depending on the light conditions. Its original color is an outstanding blue-green. This attribute, alongside a practical hardness and durability, make Alexandrite a popular and valuable choice in any piece of daywear jewelry.

Tsavorite Green Garnet:

Tsavorite often gets mistaken for Emerald, thanks to its outstanding green shade, however, it's naturally lighter and more yellow-toned than its elite counterpart. Tsavorite belongs to the class of garnets and it has tons of positive attributes, next to its sheer beauty. It is a durable gemstone yet it's also easy to cut and shape. That's why it’s often used as a substitute for Emerald in jewelry-making.  It's notable that high-quality green tsavorites are very rare and can cost almost as much as Emeralds do.

Black Opal:

Opal differs from most gemstones due to the fact that it’s a non-crystalline substance. It consists of hardened organic silica gel. Due to its water content opal needs special treatment to keep this humidity and preserve the stone from drying out. Otherwise, it gets prone to breaking or cracking. Opals come in various shapes and colors. Black opal is one specifically dark shade of the gemstone featuring lots of flashes of other colors. This means a unique and beautiful gemstone, that's a real rarity on the gemstone market.

Tanzanite:

Tanzanite is an outstanding bright, blue-purple gemstone, which was discovered relatively late in 1967, in Tanzania. As with most newer gemstones, Tanzanite was also discovered by accident, during sapphire- mining excavations. Although it’s a very expensive gemstone in its own right, Tanzanite is still cheaper than Sapphire. That's why it's often used as a substitute for the latter. This gemstone looks outstanding when incorporated in white-gold or silver jewelry.

Mystic Topaz: Also often referred to as Fire Topaz or Alaskan Ice, Mystic Topaz is not a naturally occurring gemstone but white topaz that’s treated with an artificial layer or coating, making the stone especially colorful and reflective.
