About this 1.5ct natural round diamond

This 1.5ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 626482476. Listed at 17 retailers as of November 4, 2026, with prices from $2,800 to $5,700, a $2,900 spread on the same certified stone. NZ Jewellers lists it at $5,700. 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.
