About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded H 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 2546823234. Listed at 11 retailers as of October 26, 2026, with prices from £1,160 to £2,090, a £931 spread on the same certified stone. Wholesale Diamonds Direct lists it at £2,090. 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.
