This 0.51ct natural heart sits in the half to three-quarter carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 815676658. Listed at 3 retailers as of November 2, 2026, with prices from £253 to £794, a £541 spread on the same certified stone. MOH London lists it at £794.
