About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1458230185. Listed at 6 retailers as of October 30, 2026, with prices from $2,521 to $6,150, a $3,628 spread on the same certified stone. NZ Jewellers lists it at $6,150. 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.
