This 1.67ct natural round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 2151357169. Listed at 7 retailers as of November 1, 2026, with prices from $13,748 to $23,538, a $9,790 spread on the same certified stone. MOH London lists it at $23,538. 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.
