About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by IGI 729536781. Listed at 6 retailers as of October 30, 2026, with prices from $3,080 to $8,245, a $5,165 spread on the same certified stone. NZ Jewellers lists it at $8,245. 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.
