About this 1.25ct natural radiant diamond

This 1.25ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7401103071. Listed at 2 retailers as of November 6, 2026, with prices from £2,125 to £2,967, a £843 spread on the same certified stone. 77 Diamonds lists it at £2,967. 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.
