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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2476040673. Listed at 21 retailers as of October 28, 2026, with prices from $14,052 to $26,274, a $12,221 spread on the same certified stone. NZ Jewellers lists it at $26,274. 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.
