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 6401193008. Listed at 5 retailers as of November 2, 2026, with a relatively tight 4% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
