About this 1.29ct natural heart diamond

This 1.29ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded I 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 HRD 170003125439. Listed at 3 retailers as of November 5, 2026, with prices from $5,145 to $6,309, a $1,165 spread on the same certified stone. Yorxs lists it at $6,309. 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.
