About this 0.42ct natural cushion diamond

This 0.42ct natural cushion sits in the sub-half-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 1192074612. Listed at 3 retailers as of November 1, 2026, with prices from £403 to £627, a £224 spread on the same certified stone. Yorxs lists it at £627. 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.
