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 5463655936. Listed at 17 retailers as of November 1, 2026, with prices from $11,415 to $20,707, a $9,292 spread on the same certified stone. NZ Jewellers lists it at $20,707. 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.
