About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6421733962. Listed at 20 retailers as of October 27, 2026, with prices from $9,609 to $18,395, a $8,786 spread on the same certified stone. NZ Jewellers lists it at $18,395. 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.
