Bump:
I am sure you can request one to be made with diamonds that pass HCA and Ideal-scope testing
They have been around for a long time and as you have noticed - they have a good reputation for quality.
I am also curious about their lab diamonds in jewellery. I love my WF stones (ACA melee). I wouldn't really consider buying anywhere else because I want that mind clean sparkle (I'm also overseas so buying sight unseen and returns are a hassle). But I've been putting off buying a tennis bracelet/bangle because I haven't quite got the right feels around how well their lab diamond melee is cut. Hopefully someone who has their lab diamond jewellery can chime in and let us know.
I would also love to hear if anyone has purchased a lab diamond tennis bracelet from Whiteflash. I've been debating if I should buy a tennis bracelet from Alex Parks, or if it's worth it to spend more and purchase from Whiteflash.
