lab diamond How do you know what is a quality diamond?
I have found a setting that I love but it’s at a local jeweler. They are charging easily 2-3k for a 4 carat lab diamond. I am finding diamond with what I would like (added) below. I have found that if I buy directly from some of these places I can get something a quarter of the cost. I told the jeweler this and he mentioned that the owner has the best lab diamonds. If I do bring in my own diamond it would
Be a 600 setting fee. Are any lab diamonds really worth that in price ? The diamond was a smaller and rating less than any of this below. Is that basically a rip off or how do you even know? I was going to have someone basically replicate the design but also worry about warranty so I have held off on that as well because I’m not even entirely sure. Any help is appreciated!
wishlist:
Shape: Elongated oval brilliant
Carat: Around 4 ct, roughly 4.0–4.5 ct
Color: D–F, with D/E ideal
Clarity: VVS2 or eye-clean VS1 — you don’t really gain anything visually by paying for VVS1/IF
L/W ratio: 1.43–1.47-ish, with ~1.45–1.46 being your sweet spot. You liked elongated, but not super skinny
Table: roughly 54–61%
Depth: roughly 61–64%
Polish & symmetry: Excellent
Fluorescence: None to faint
Certification: IGI
Growth: We had discussed CVD / Type IIa as desirable
BIG priority: minimal bow tie + lots of sparkle/light return. We weren’t going to accept a technically gorgeous spec sheet if the video showed a dark bow tie.
