About this 3.03ct natural marquise diamond

This 3.03ct natural marquise sits in the three to five 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 2566780508. Listed at 15 retailers as of November 2, 2026, with prices from $43,574 to $71,868, a $28,294 spread on the same certified stone. MOH London lists it at $71,868. 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.
