About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1538257514. Listed at 20 retailers as of October 30, 2026, with prices from $11,244 to $20,390, a $9,146 spread on the same certified stone. NZ Jewellers lists it at $20,390. 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.
