About this 1.55ct natural radiant diamond

This 1.55ct natural radiant sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7301120821. Listed at 6 retailers as of November 6, 2026, with prices from £2,947 to £3,935, a £988 spread on the same certified stone. Yorxs lists it at £3,935. 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.
