This 1.51ct natural round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 2241040984. Listed at 17 retailers as of October 26, 2026, with prices from $5,617 to $12,040, a $6,422 spread on the same certified stone. MOH London lists it at $12,040. 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.
