About this 1.71ct natural radiant diamond

This 1.71ct natural radiant sits in the one-and-a-half to two carat band, graded G 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 15600072. Listed at 6 retailers as of October 30, 2026, with prices from £5,732 to £7,665, a £1,933 spread on the same certified stone. Jared lists it at £7,665. 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.
