About this 2.51ct natural marquise diamond

This 2.51ct natural marquise sits in the two to three carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 260000001497. 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.
