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 SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6197060931. Listed at 3 retailers as of November 6, 2026, with prices from $2,694 to $4,057, a $1,363 spread on the same certified stone. 77 Diamonds lists it at $4,057. 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.
