About this 0.59ct natural round diamond

This 0.59ct natural round sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 1555554673. Listed at 12 retailers as of October 31, 2026, with prices from £486 to £804, a £318 spread on the same certified stone. Frank Darling lists it at £804. 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.
