About this 1.23ct natural heart diamond

This 1.23ct 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 5556229880. Listed at 9 retailers as of November 5, 2026, with prices from $2,839 to $8,051, a $5,211 spread on the same certified stone. NZ Jewellers lists it at $8,051. 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.
