This 1.25ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 6415581706. Listed at 10 retailers as of October 29, 2026, with prices from $2,234 to $4,873, a $2,640 spread on the same certified stone. MOH London lists it at $4,873. 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.
