About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2135717786. Listed at 5 retailers as of November 1, 2026, with prices from £2,144 to £4,313, a £2,169 spread on the same certified stone. MOH London lists it at £4,313. 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.
