About this 0.65ct natural cushion diamond

This 0.65ct natural cushion sits in the half to three-quarter 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 2191030200. Listed at 10 retailers as of October 28, 2026, with prices from £810 to £1,718, a £909 spread on the same certified stone. MOH London lists it at £1,718. 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.
