About this 0.64ct natural marquise diamond

This 0.64ct natural marquise sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2231788264. Listed at 3 retailers as of November 1, 2026, with prices from £863 to £1,336, a £474 spread on the same certified stone. MOH London lists it at £1,336. 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.
