Fancy yellow/green/blue sapphire* briolettes are UNDRILLED. Attention PMC workers: They have no holes. Some of them are just yellow-green and some are blue/green/bicolor. Pretty and very transparent, they might be perfect to embed in precious clay (PMC) and fired in place. They'll mimic pear shaped stones that way.
Ranging in size from ~4 mm to 6 mm in length, the lot is 6.5 total carats. But since they have no wholes, I cant really use them, so I'm only charging $3/carat! (And they are on sale through September 21st so the price you see includes a 10% discount).
Did I mention that they have NO HOLES?
* A note about the sapphires: Did you know that pure corundum is colorless? Blue corundum is referred to as "sapphire" in the industry. Red corundum stones are called "ruby". Yup, they are the same mineral with different impurities that cause the different colors. All the colors of the rainbow except red and blue are called "fancy colored sapphires".
I use mined-from-the-ground stones that are subject to industry standard treatments. Sapphires and rubies are almost always heat-treated to enhance the color. The treatment is permanent. Sometimes additional additives such as beryllium and cobalt or leaded glass have been used. Beryllium has become pretty common and lowers the cost of the stone somewhat. Glass and cobalt additives drastically reduce the value of the stone so I try to avoid them. I will always disclose the information if I know or suspect about treatments. These are fairly old stock. They have certainly been heated and these stones may have been beryllium treated. However, I purchased them before the glass treatment became scandalously prevalent so I doubt there is any glass present in any of them.
These are pretty fancy sapphires, but they are "bead quality" which means that their wholesale prices are low compared to cut gemstones that need to be individually set. I try to pass the savings on to my customers. This is why they cost considerably less than other rainbow sapphire jewelry you may find in the marketplace. Also, I just don't believe in marking up jewelry or gems by 1000% like some in the industry do. So indulge, and enjoy!
