About this 0.46ct natural radiant diamond

This 0.46ct natural radiant sits in the sub-half-carat band, graded H 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 2546187200. Listed at 3 retailers as of October 30, 2026, with prices from £257 to £310, a £54 spread on the same certified stone. Michael Trio lists it at £310. 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.
