Diamonds have never been rare gemstones. That’s not the material we tend to focus on.
Most cutters work in color gemstones. That’s the material that allows a lot more art, and is also where all the actually rare stuff is.
I think diamond currently accounts for about 5% of our engagement ring business, and generally they just want it because someone told them they have to buy a diamond. Mostly lab material because no one really cares.
Rest is all color gemstones.
