3.Natural Oregon Sunstone VS Copper Diffused Andesine
Copper diffused andesine and natural Oregon sunstone are nearly identical when viewed from the front



a. The color of copper-diffused andesine is distributed and aggregated along the cleavage, and is clearly visible under cross-polarized light. The color of natural Oregon Sunstone is not distributed and clustered along the cleavage.


b. Under cross-polarized light, when viewed from the back, the color of natural Oregon sunstone is clear and bright, while when viewed from the back of copper-diffused andesine, the color is opaque and ribbon-like, hindering the transparency of the gemstone.

Spectacular!

Finally -- a pigeon-blood-red gem I can afford!

Is the copper-diffused andesine a (commercial) mimic? Did you acquire these intentionally or was it part of the "learning process"?

These copper-diffused andesines are all samples I bought from dealers who sell them under the names of Tibetan sunstone, Congolese sunstone, and natural pigeon-blood red andesite. I bought them at the price of copper diffused andesine.
