About this 0.53ct natural round diamond

This 0.53ct natural round sits in the half to three-quarter carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 2566401532. Listed at 16 retailers as of November 4, 2026, with prices from £648 to £1,438, a £790 spread on the same certified stone. Flawless Fine Jewelry lists it at £1,438. 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.
