About this 0.65ct natural cushion diamond

This 0.65ct natural cushion sits in the half to three-quarter carat band, graded G 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 7538607979. Listed at 9 retailers as of November 2, 2026, with prices from £297 to £440, a £143 spread on the same certified stone. Jared lists it at £440. 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.
