About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded G colour (near-colourless) and I2 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1509061506. Listed at 3 retailers as of November 5, 2026, with prices from £915 to £1,499, a £584 spread on the same certified stone. Wholesale Diamonds Direct lists it at £1,499. 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.
