About this 0.83ct natural heart diamond

This 0.83ct 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 6541198646. Listed at 17 retailers as of November 5, 2026, with prices from £633 to £1,914, a £1,281 spread on the same certified stone. NZ Jewellers lists it at £1,914. 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.
