About this 0.65ct natural round diamond

This 0.65ct natural round sits in the half to three-quarter carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 2537181100. Listed at 9 retailers as of November 4, 2026, with prices from £1,322 to £2,480, a £1,158 spread on the same certified stone. With Clarity lists it at £2,480. 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.
