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 18 retailers as of October 30, 2026, with prices from $10,231 to $18,559, a $8,328 spread on the same certified stone. NZ Jewellers lists it at $18,559. 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.
