About this 1.31ct natural heart diamond

This 1.31ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 260000010489. Listed at 6 retailers as of November 1, 2026. 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.
