Looking at your picture I am seeing what looks like a concoidal fracture near the top of the front face of the stone above the trigons.akmraju|1474468086|4079206 said:Thanks there!
Actually I got a chance to take a pic of the stone from someone's pile of stones collection that I intend to offer a price.
I got intrigued by the trigons in on the surface and my heart skipped a beat noticing those. and again when I did the fogging test. the vapor evaporated almost instantly.Then I googled for the triangular etching on crystals. I didnt get a chance to get it tested or can find any reliable testers who can confirm honestly. I wanted some expert feedback based on images i posted. I am buying a diamond tester online and doing what other tests I can by this weekend and needed some expert opinion from the expert members with Pricescope.
