About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7536718788. Listed at 19 retailers as of October 30, 2026, with prices from £639 to £2,151, a £1,512 spread on the same certified stone. NZ Jewellers lists it at £2,151. 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.
