- fallingknife 3y agoDiamond is not the energetically favorable form of carbon at room temperature and pressure, so to manufacturer there will always need to be expensive tricks. Not as expensive as digging out tons of kimberlite, but still not cheap.

- kemayo 3y agoA 3 karat diamond is still a crystal (approximately) the size of your pinkie nail that takes a fairly large energy input to create... and only the ones that've grown clear and without flaws are viable for jewelry purposes. The bigger it gets, the lower the yields are at the appropriate quality level, and so the more effort / waste is involved in getting one. (As opposed to industrial diamond uses, which mostly don't have those requirements and so have their price even more heavily impacted by synthetics.)
- jdietrich 3y agoSilicon is a cheap, abundant material. Making very large, very pure silicon crystals for the semiconductor industry is complex and expensive. The small, ugly diamonds we use for industrial abrasives cost pennies per carat.
- londgine 3y ago$3k is a bit much for me to feel comfortable spending at a store well known for selling Chinese knockoffs. Is there a way for a layman to test that the stone is indeed a diamond, and not something like lab made cubic zirconia?
- rcme 3y agoUse a credit card, take it to be tested, and do a charge back for fraud if it doesn’t meet specifications.
- Reubend 3y agoI do see some entries like you're describing on Alibaba for bulk orders, but is there anything for consumers buying a single gem in this price range? I couldn't find anything on other websites that's as cheap.
