About this 0.63ct natural cushion diamond

This 0.63ct natural cushion sits in the half to three-quarter carat band, graded J 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 6502525116. Listed at 10 retailers as of November 4, 2026, with prices from $382 to $997, a $615 spread on the same certified stone. MOH London lists it at $997. 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.
