About this 0.78ct natural heart diamond

This 0.78ct natural heart sits in the just-under-one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2516467553. Listed at 5 retailers as of November 2, 2026, with prices from £582 to £936, a £354 spread on the same certified stone. GemTrove lists it at £936. 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.
