This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 754512482. Listed at 20 retailers as of October 30, 2026, with prices from $3,235 to $6,968, a $3,733 spread on the same certified stone. NZ Jewellers lists it at $6,968. 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.
