About this 1.51ct natural round diamond

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 November 2, 2026, with prices from $4,129 to $8,904, a $4,776 spread on the same certified stone. NZ Jewellers lists it at $8,904. 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.
