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 VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1528591978. Listed at 24 retailers as of November 2, 2026, with prices from $6,171 to $13,951, a $7,780 spread on the same certified stone. NZ Jewellers lists it at $13,951. 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.
