About this 1.08ct natural cushion diamond

This 1.08ct natural cushion sits in the classic one-carat band, graded G colour (near-colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2151247135. 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.
