About this 0.57ct natural cushion diamond

This 0.57ct 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 2507507689. Listed at 2 retailers as of October 26, 2026, with prices from €788 to €921, a €132 spread on the same certified stone. Fonder Diamond lists it at €921. 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.
