About this 1.53ct natural radiant diamond

This 1.53ct natural radiant sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6561499159. Listed at 14 retailers as of November 4, 2026, with prices from £4,607 to £7,587, a £2,979 spread on the same certified stone. MOH London lists it at £7,587. 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.
