DIAMOND PERFORMANCE
Polish Excellent
Symmetry Very Good
Fluorescence None
Eye-Clean Inquire
Polish
The aspect of finish related to the quality of facet flatness and luster. Each facet should be polished to a mirror finish.
Symmetry
Also known as ‘meet point’ symmetry, describes the degree to which contiguous facets meet precisely at the proper places all around the diamond.
Fluorescence
Some diamonds react to strong ultraviolet light waves by emitting light, usually blue, in a process known as photoluminescence. More information can be found on our fluorescence page.
Eye-Clean
The ability or inability to see inclusions in a diamond with the naked eye. Our definition of eye-clean: No inclusions visible to the naked eye of a person with 20/20 vision when viewing the diamond in the face-up position at a distance of approximately 10 inches under normal overhead lighting. Distance, lighting and human vision all influence this judgment.

I wish to express my gratitude for the lovely pendant and your assistance. She is delighted with the gift, which stands out in Vietnam, My understanding is that, diamonds in VN are of lower quality, so Whiteflash is a cut above (pun intended). Thank you once again.

I wanted to wait a couple of months before leaving this review to make sure the rings we got were high-quality. We’ve visited 3 other jewelers before deciding on Whiteflash. We were referred by a relative after their own positive experience. Our consultant Liza was amazing. She super informative, patient and never pushy. We really appreciated that the whole process felt relaxed. Our custom order arrived in less than a month. My partner’s custom ring turned out absolutely stunning! Liza helped bring our ideas together and used nature as inspiration to create something unique, beautiful and durable. Overall, we had such a great experience with Whiteflash and haven’t had any issues with our rings so far. Highly recommend! :)
