Since I make jewelry, I'm always lusting after beautiful stones, too... but I can't even begin to afford them. I do have some garnets and citrines and turquoise and various quartzes, but they're only beads, not "settable" stones. Oh -- except for one very beautiful green onyx cabochon that I wire-wrapped into a hammered-silver bracelet years ago!
I love watermelon tourmaline, ametrine, opals, and pearls... and I love cabochons, but I'm also crazy for a simple emerald cut.
And I don't like diamonds, either! I can't enjoy their beauty, knowing the backstory... and the absurd amounts of money that are spent on them.
And to tell the truth -- a beautiful glass stone that looks like the real thing is just fine
with me. It would be nice to own the genuine article, with all its history and science and mysterious inner life... but I've had to learn to love beauty I can afford.
