About this 0.91ct natural radiant diamond

This 0.91ct natural radiant sits in the just-under-one-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 1425863889. Listed at 12 retailers as of November 1, 2026, with prices from £639 to £1,564, a £925 spread on the same certified stone. MOH London lists it at £1,564. 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.
