About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1463913592. Listed at 15 retailers as of November 6, 2026, with prices from £1,252 to £2,604, a £1,351 spread on the same certified stone. Wholesale Diamonds Direct lists it at £2,604. 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.
