About this 3.02ct natural marquise diamond

This 3.02ct natural marquise sits in the three to five carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559197646. Listed at 16 retailers as of November 2, 2026, with prices from £20,390 to £36,106, a £15,716 spread on the same certified stone. MOH London lists it at £36,106. 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.
