Not Sure if what I have to offer will work for you, but I have a few huge stones. Sapphires, Emerald and Rubies
They are faceted, The ruby I have is dyed and around 720ct sphere cut(looks like a small faceted tennis ball)
The emeralds and sapphires all range from 50ct to 200cts in a variety of cuts.
I also have very nice Peridots, Citrines, Amethyst, Smokey Quartz, and Tanzanite. These are much smaller faceted stones between 1ct and 45ct. I also have a vast Moissanite collection to the tune of 200+ stones.
If you have any interest in these, or you would like a few pictures just let me know.
Feel free to contact me.
