2.72ct Andesine Labradorite



Andesine is a plagioclase feldspar like labradorite and was discovered in the Congo near the Nyiragongo Volcano sometime in 2003. It's neat because there is a faint metallic shimmery phenomenon called labradorescense to the stone. There is some mystery to Andesine as it is such a new stone and there are a lot of fakes coming from China which is copper diffused labradorite.

From everything we can see, this stone does not have copper diffusion treatment and it is in fact, andesine. As we receive more testing equipment, we'll continue to test this stone but the fact that it is such a light apricot color tells us that it is untreated.

Caution: Andesine is not tolerant of heat, so please disclose to your jeweler that it is andesine before they set the stone to avoid harming the stone during setting. It is also a fragile stone, so please always remove your andesine before doing any physical activity.
