About this 0.45ct natural round diamond

This 0.45ct natural round sits in the sub-half-carat band, graded H colour (near-colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 1548895962. Listed at 4 retailers as of November 4, 2026, with prices from £373 to £497, a £125 spread on the same certified stone. 77 Diamonds lists it at £497. 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.
