Diaspro Jasper is derived from the Greek for "spotted stone". Jasper is usually considered a chalcedony, but scientists put it in a group by itself because of its grainy structure. Finely grained, dense jasper contains up to twenty percent foreign materials that determine its color, streak and appearance. Uniform jasper is rare; it is usually multicolored, striped, spotted or flamed.
Chrysoprase, a bright apple green translucent chalcedony, is the most valued. Some treasured jasper stones exhibit a picture that appears to be taken from nature and are called "landscapes". Another specialty is bloodstone or blood jasper, also known as "heliotrope"; a dark green chalcedony or jasper with flecks of red. Most jasper is opaque and takes an excellent polish. Jasper is used for ornamental objects, cabochons and stone mosaics. Care must be taken during cutting. Banded jasper tends to separate along the layers.

The opals I ordered are absolutely beautiful, very fiery and well-cut. The pictures online didn’t do them justice. Shipping did take longer than expected (I chose the standard option), but the gemstones I received were definitely worth the wait.
I have purchased gems from Gem Select twice a year, for more than a few years.Gem select is the best place to buy gems. The selection and presentation are genuine. What you see is what you get, keeping in mind the carat weight, and measurements they have listed. Never have I been disappointed with any gem I have received from them. Nan
GemSelect has a great selection of smaller cabochons. Many other retailers do not. Plus, the photo of the stone is the one you are purchasing. Shipping from Thailand is nearly as fast as from within the US. Stones are tightly and neatly packaged.
