Mineral Classics - Andesine Gems August 2008

Andesine is a variety of Albite / Plagioclase Feldspar which is extremely rare in gem grade material with orange or red colors. These new stones were initially said to be discovered in 2002 in the Democratic Republic of Congo and as of the initial discovery of these stones, no more Andesine has been offered for sale. I have been told that this material is actually coming from Tibet, and this has been confirmed by a few sources. The amazing red color of these Andesines is caused by Copper content. The clarity of these stones is very impressive for Feldspar, which rarely forms in red crystals, especially with this clarity. The most well known red Feldspar is the Oregon Sunstone which is Labradorite, and also has Copper content that causes a variety of colors ranging from red to pink to orange to green and rarely blue. This new red Andesine (also found in orange, green, blue and colorless hues) contains more copper than the Oregon Sunstone. Truly this is one of the rarest and most valuable Feldspar varieties in the world. You won't find this material in many stores or dealer's inventories. They are arguably the cleanest, brightest and vivid Feldspar stones in the world.

PLEASE NOTE: There has been some uncertainty as to which species / variety of Feldspar these gems may be. In order to properly identify the correct species / variety of Plagioclase Feldspar, along with any possible treatments to these gems, testing is currently being performed on this material at GIA laboratories in Carlsbad, California. Additional details and/or information about these gems will be posted on our website as it becomes available. Thank you.
