This 1.51ct natural round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 7558636517. Listed at 18 retailers as of November 1, 2026, with prices from $6,994 to $14,500, a $7,506 spread on the same certified stone. MOH London lists it at $14,500. 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.
