This 1.51ct natural round sits in the one-and-a-half to two carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 6525130285. Listed at 16 retailers as of November 4, 2026, with prices from $12,540 to $20,330, a $7,790 spread on the same certified stone. MOH London lists it at $20,330. 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.
