About this 0.52ct natural cushion diamond

This 0.52ct natural cushion sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3525308256. Listed at 3 retailers as of October 31, 2026. 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.
