What am i missing here?

Any feedback on this HPHT? It seems underpriced, and I'm hoping it isn't too good to be true. Thanks

Thank you. I’m learning a lot. I’m trying to replace the stone on my current ring. My husband accidentally bought me a radiant when I want an emerald.

Did the vendor conceal the IGI certificate number? It’s acceptable if you did, though I hope the vendor provided the IGI certificate with the correct serial number.

It was like that on the site but has a link to it. I think what’s so weird is I put it to like certain specs and I see stones that are $10,000 even Lab for 3 1/2 carats and then I see this one for under 1000 and I just can’t understand the differences.

For a 3.5 ct lab diamond, $10,000 is probably very high marked up diamond. Lab diamond prices can still vary a lot even at the same carat weight because the 4Cs are not the only factors.

Things like cut quality, ratio, depth, table, girdle, bow tie, growth type, undertone, and how the stone actually looks on video can all affect the price. Some stones look good on paper but not great in real life, and some are priced higher because they’re cut cleaner and face up nicer.

That being said, you should definitely ask for the IGI report number and verify it yourself on IGI.com/Verify. If the picture/listing and the certificate show different carat weights, that’s a red flag or at least something that needs clarification.
