About this 0.45ct natural round diamond

This 0.45ct natural round sits in the sub-half-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 3515023687. Listed at 20 retailers as of November 4, 2026, with prices from £399 to £1,494, a £1,095 spread on the same certified stone. NZ Jewellers lists it at £1,494. 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.
