About this 1.27ct natural round diamond

This 1.27ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 523290758. Listed at 12 retailers as of October 30, 2026, with prices from $3,470 to $8,101, a $4,631 spread on the same certified stone. NZ Jewellers lists it at $8,101. 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.
