Gemstone # CUPRITENAM3531 Name: Cuprite Locality: Namibia Weight: 35.31 carats Size: 18.26 mm Price per Carat: $ 100.00 Price For Stone: $ 3531.00

Cut: Modified Cut Corner Trillion Color: Deep Red Clarity: Eye Clean Cut by Us: No Availability: Available

Comments:

Fine quality Cuprite gems from Namibia are hard to come by these days, and it would be very difficult to find another stone such as this (35.31 carats) on the market. This stone was part of our personal collection and we recently decided to sell the stone giving you the opportunity to own a superb collector quality rare gem. For Cuprite, this is a very large faceted stone and the material from Namibia is no longer being found.  Cuprite is very, very difficult to facet due to the soft nature of the material, so stones like this are marvelous, as it takes a skilled cutter with great patience and knowledge to create such a special gem.  The stone was difficult to photograph, and certainly better in person.  Anyone who has seen faceted Cuprite knows that the stones are incredibly lively, with their distinctive metallic cochineal red appearance.  According to Joel Arem, one-time curator for the Smithsonian National Gem and Mineral Collection in Washington DC, faceted Cuprite of any size is considered one of the most collectible and spectacular gems in existence.  It is a prerequisite of every good rare gem collection to have a Cuprite, and this stone would make an ideal addition to any fine rare gem suite.
