About this 0.81ct natural heart diamond

This 0.81ct natural heart sits in the just-under-one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7488623888. Listed at 17 retailers as of November 5, 2026, with prices from £810 to £2,061, a £1,251 spread on the same certified stone. NZ Jewellers lists it at £2,061. 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.
