About this 1.27ct natural oval diamond

This 1.27ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded J 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 170003065987. Listed at 4 retailers as of November 4, 2026, with prices from £2,486 to £4,267, a £1,781 spread on the same certified stone. MOH London lists it at £4,267. 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.
