About this 0.53ct natural marquise diamond

This 0.53ct natural marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2141022633. Listed at 3 retailers as of November 4, 2026, with prices from £350 to £508, a £159 spread on the same certified stone. DreamStone lists it at £508. 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.
