Full details
A round brilliant is faceted for brilliance and sparkle, and at 0.51 carats this one measures about 5.20–5.23 mm across. E is in the colorless range (D–F): it will face up icy white, in white metal or yellow gold. VS1 inclusions are minor and usually need 10× magnification to see. In a round of 0.51 carats that typically means eye-clean, though the grade does not say where the inclusion sits. It suits almost any setting: a classic four- or six-prong solitaire, a halo, or a three-stone ring.

Is this a real diamond? What does HPHT mean?
Yes. It is a lab-grown diamond: carbon in the same crystal structure as a mined diamond, with the same hardness and optical properties. It was grown by HPHT (high pressure, high temperature). The growth method doesn't make a diamond better or worse on its own; the grades and how it looks do.
