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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6462679137. Listed at 22 retailers as of October 28, 2026, with prices from $11,249 to $24,177, a $12,928 spread on the same certified stone. NZ Jewellers lists it at $24,177. 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.
