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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1475983178. Listed at 6 retailers as of November 5, 2026, with prices from £749 to £903, a £154 spread on the same certified stone. Ritani lists it at £903. 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.
