About this 0.45ct natural radiant diamond

This 0.45ct 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 1176145963. Listed at 12 retailers as of November 1, 2026, with prices from £529 to £1,193, a £664 spread on the same certified stone. Moon Ocean lists it at £1,193. 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.
