Kornerupine, sometimes referred to as prismatine, is a rare gemstone first discovered in Greenland named after the Danish explorer Andreas Nikolaus Kornerup. Kornerupine occurs in variety of colors, including white, pink, yellow, brown, green and blue. Kornerupine typically exhibits strong pleochroism, usually from yellowish green to reddish brown. Kornerupine has a hardness of 6.5 to 7 on the Mohs scale and is hard enough for jewelry, but owing to its rarity, it is mainly a collector's stone.

I purchased a stone as a gift for my wife. I'm waiting to see how soon I get it and how well it matches the description on the web site. Future orders may follow based on the overall experience of this one.

If you want a gem that you can trust to not be treated, or if it is ita's disclosed this is the place! Therea's something for everybody. I really like knowing that the picture of the item is the one Ia'm buying, not a sample or stock photo. If you make jewelry, buy gems here! You can even buy a gem and have it set by a jeweler. Again, they have an amazing inventory, and prices are more than fair. You wona't be disappointed! I just wish they sold uncut gems. Sometimes I just want a specimen in the crystal form. Ia'm surprised they had no quartz from Arkansas, but they have a great selection of anything Ia've ever looked for.

Huge selection of gemstones. This is my go to site for gems that aren't available through online retailers like Rio or Stuller. Perfect for custom and one of a kind pieces.
