About this 0.75ct natural heart diamond

This 0.75ct natural heart 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 stated by the retailer rather than the lab and certified by GIA 5546379645. Listed at 3 retailers as of November 2, 2026, with prices from £620 to £1,954, a £1,334 spread on the same certified stone. NZ Jewellers lists it at £1,954. 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.
