This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 743523994. Listed at 21 retailers as of November 5, 2026, with prices from $3,854 to $8,775, a $4,921 spread on the same certified stone. NZ Jewellers lists it at $8,775. 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.
