About this 0.45ct natural cushion diamond

This 0.45ct natural cushion sits in the sub-half-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2557002145. Listed at 4 retailers as of November 4, 2026, with prices from £336 to £840, a £504 spread on the same certified stone. MOH London lists it at £840. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
