I know this lesson was supposed to be diamonds but I forgot so we'll have a lesson on Ametrines.
They look rich and luscious and gorgeous and they'll all synthetic and photoshopped for glitz.
This one was too dark in the amethyst section, it's almost burgundy but in the hand, the shade was the right colour for amethyst. The citrine section, shown here as gold to deep gold, was a pale lemon colour, not right for a geniune ametrine. The size was large, too good to be true and it was. It appears to be laboratory grown, by looking through a loup but not by chemical testing.
Now I was sure this was a winner. The shading of the purple, pink and yellow is beautiful and I loved the cut and shape but again, opinion is that it is also a laboratory grown synthetic.
Look at all the photoshopped sparkly bits on this delightful heart. In the hand, it is a dark mauve/violet on one corner, violet on the bottom and the citrine band across the middle is a lightish lemon/yellow colour. Opinion is synthetic laboratory grown.
The gemmologist who is advising me on these stones, in fact on all of the gems that I've bought, is qualified but is doing this by looking with an experienced eye. It will cost me a great deal of money to have them assessed by chemical and other tests.
So, after a post not long ago about ametrines, why did I fall for and buy these? Because the country of origin was listed as Bolivia, the home of ametrines and it was an Australian seller with a supposedly good reputation.
If they had been listed as synthetic, I still would have bought them but not paid as much because I love the colours and shapes.
I will get to those diamonds but the minefield that is simulated diamonds needs to be negotiated with eyes wide open.
