About this 0.78ct natural round diamond

This 0.78ct natural round sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 1517138458. Listed at 6 retailers as of November 4, 2026, with prices from £2,379 to £4,575, a £2,196 spread on the same certified stone. With Clarity lists it at £4,575. 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.
