About this 0.77ct natural round diamond

This 0.77ct natural round sits in the just-under-one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 1558831288. Listed at 14 retailers as of October 26, 2026, with prices from £964 to £1,573, a £609 spread on the same certified stone. Wholesale Diamonds Direct lists it at £1,573. 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.
