About this 0.64ct natural cushion diamond

This 0.64ct natural cushion sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6541429582. Listed at 4 retailers as of November 2, 2026, with prices from £293 to £377, a £83 spread on the same certified stone. 77 Diamonds lists it at £377. 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.
