About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5446975925. Listed at 18 retailers as of October 30, 2026, with prices from $4,222 to $9,617, a $5,396 spread on the same certified stone. NZ Jewellers lists it at $9,617. 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.
