About this 3.01ct natural marquise diamond

This 3.01ct natural marquise sits in the three to five carat band, graded H 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 5566650693. Listed at 22 retailers as of November 4, 2026, with prices from £30,945 to £54,380, a £23,435 spread on the same certified stone. MOH London lists it at £54,380. 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.
