About this 0.9ct natural heart diamond

This 0.9ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2185831647. Listed at 16 retailers as of October 30, 2026, with prices from £1,684 to £4,323, a £2,639 spread on the same certified stone. NZ Jewellers lists it at £4,323. 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.
