About the Brilliance.com 0.52 Carat E Color VVS1 Clarity Super Ideal Cut Round Loose Diamond GIA Certified

This is a single 0.52 carat round natural diamond, about 5.12 mm across, graded E color, VVS1 clarity and Super Ideal cut by Brilliance.com and certified by GIA. E color is near the top of the scale with no visible tint, and VVS1 inclusions are extremely hard to find even under 10x magnification. The Super Ideal cut is the store's top grade, cut for maximum light return. At $1,390 at Brilliance.com as of November 5, 2026, it is the only new price listed, so there is no lower recent price to compare against.

    Questions and answers

    Is E color and VVS1 overkill for a half-carat diamond?
    At 0.52 carat, most shoppers could drop to F–G color and VS clarity and see little difference by eye, often for less money. E/VVS1 buys peace of mind and a cleaner certificate, not visible sparkle.
    What does Super Ideal cut mean here?
    It is Brilliance.com's own top cut grade, meaning the 57 or 58 facets are cut to return as much light as possible. GIA does not issue a Super Ideal grade, so check the certificate's cut, polish and symmetry ratings.
    What comes with the diamond?
    The loose diamond and its GIA certificate. A setting, ring mounting and any sizing are separate purchases.
    Is $1,390 a good price?
    Only one new price is listed, $1,390 at Brilliance.com as of November 5, 2026, so there is no competing quote to judge against. Compare GIA-certified 0.5 carat E/VVS1 Super Ideal stones elsewhere before deciding.
    Will 5.12 mm look small on a ring?
    A 5.12 mm round reads as a classic half-carat center stone. On a size 6 finger it looks proportionate; on larger hands or with a thin band it can appear smaller.
    Can I return it if the stone disappoints?
    Return terms are set by Brilliance.com, so confirm the window and any restocking fee before ordering. Keep the GIA certificate with the stone, since returns usually require it.
