About this 0.43ct natural radiant diamond

This 0.43ct natural radiant sits in the sub-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 2467081692. Listed at 15 retailers as of October 30, 2026, with prices from £286 to £1,097, a £811 spread on the same certified stone. NZ Jewellers lists it at £1,097. 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.
