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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 7558308329. Listed at 23 retailers as of October 30, 2026, with prices from £6,268 to £11,300, a £5,033 spread on the same certified stone. NZ Jewellers lists it at £11,300. 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.
