About this 0.75ct natural heart diamond

This 0.75ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 170003125106. Listed at 2 retailers as of November 2, 2026, with prices from $3,038 to $3,525, a $487 spread on the same certified stone. Yorxs lists it at $3,525. 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.
