About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 260000015760. Listed at 7 retailers as of November 4, 2026, with prices from £3,323 to £6,052, a £2,730 spread on the same certified stone. MOH London lists it at £6,052. 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.
