About this 1.02ct natural cushion diamond

This 1.02ct natural cushion sits in the classic one-carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7548427192. Listed at 10 retailers as of November 5, 2026, with prices from £478 to £939, a £461 spread on the same certified stone. Wholesale Diamonds Direct lists it at £939. 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.
