Q&A: Looking for a Round Diamond With 8mm x 8mm Diameter for a Platinum Setting

By Mike Fried, Updated July 3, 2025

I would like a diamond that is 8mm x 8mm, G color and eye clean. Any suggestions? Also, will I notice fluorescence or get one with none?

Thanks.

I’d be happy to help you. What shape diamond are you looking for?

Also, can you give me your ballpark figure of what you’re looking to spend?

I am looking for a super sparkly, white-white diamond that is 7.75 x 7.75 round in platinum.

Thanks!

I found two diamonds that look amazing and will be crystal white:

Blue Nile LD07866330

Both are beautifully cut and will look bright and brilliant. Let me know what you think.
