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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2427292759. Listed at 5 retailers as of November 6, 2026, with prices from $2,461 to $3,854, a $1,393 spread on the same certified stone. Yorxs lists it at $3,854. 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.
