About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded J 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 6237852733. Listed at 8 retailers as of October 30, 2026, with prices from $2,374 to $6,742, a $4,369 spread on the same certified stone. NZ Jewellers lists it at $6,742. 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.
