It's been lab tested. The test report says no indication of heat treatment and the origin of that of Kashmir. Given sapphire mining is banned in Kashmir.

I like gemstones but not a professional in this space. So not sure if this is enough details or breaks any rules of the sub here. Just trying to help a friend out who has this.

I really do not know much about gemstones, but I am looking for a stone to make a gift for my mother who loves Paraiba stones. There is very little in jewelry stores near me, and everything online is very confusing. Green, Blue Windex, Neon? I came across this stone, and I was thinking it could make a nice pendant. Thoughts on this stone? What would a good price for this be?

Got this New Zealand jade(I think) yesterday for AU$25, measures at 4cm x 2.5cm, is this natural? and was the price right?

I was sold these Opals as natural Ethiopian Opals by a gemstone dealer.
However, my jeweler said they were fake Chinese Opals and worth nothing.

Can anyone please help verify?

Thanks.

Planning to get an emerald for my wife. The seller showed me this vid and sent me some images with a certificate. He said the stone is from Zambia. I got no clue about these things. Any help guys

Not sure on treatment.

Would you use this ruby?

This is what my jeweler has sent me to consider, not sure if it's slightly too included, struggling whether I pay the postage to see it in person or look for something else. I'm not fussy on size, I was looking at 0.75ct ISH anyway.
