The most prized of all the Chalcedonies has to be the nickel rich silicate Chrysoprase. This material has been mentioned as early in history as 23 AD, but was not mined commercially until about 1740.
Chrysoprase is one of the most sought after gem materials for carving, cabochons, and inlay work.
This material has a hardness of 7 to 7.3 and will take an excellent polish with either Diamond or Cerium Oxide. One of our most popular cabbing materials. This new Chrysoprase is sure to be a hit, as this material does not have the amount of waste normally associated with Australian Chrysoprase. A beautiful pistachio to apple green, you can expect to produce some beautiful gemstones or carvings from this rough. 6 to 25 lbs.
