About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551229350. Listed at 12 retailers as of November 5, 2026, with prices from £3,655 to £8,118, a £4,463 spread on the same certified stone. NZ Jewellers lists it at £8,118. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
