About this 1.02ct natural heart diamond

This 1.02ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1525714815. Listed at 18 retailers as of November 5, 2026, with prices from $1,458 to $4,534, a $3,076 spread on the same certified stone. NZ Jewellers lists it at $4,534. 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.
