About this 1.26ct natural marquise diamond

This 1.26ct natural marquise 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 standard cut grade stated by the retailer rather than the lab and certified by GIA 5231971694. Listed at 8 retailers as of November 2, 2026, with prices from $5,223 to $11,017, a $5,795 spread on the same certified stone. MOH London lists it at $11,017. 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.
