This 1.37ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5446958206. Listed at 2 retailers as of October 29, 2026, with prices from £3,248 to £4,467, a £1,220 spread on the same certified stone. 77 Diamonds lists it at £4,467. 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.
