About this 4.03ct natural marquise diamond

This 4.03ct natural marquise sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1246100179. Listed at 19 retailers as of October 31, 2026, with prices from £41,073 to £75,723, a £34,650 spread on the same certified stone. MOH London lists it at £75,723. 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.
