This 1.51ct natural round sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 5231790364. Listed at 4 retailers as of November 1, 2026, with prices from £15,361 to £20,753, a £5,392 spread on the same certified stone. Yorxs lists it at £20,753. 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.
