About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6522691780. Listed at 22 retailers as of October 29, 2026, with prices from $7,776 to $16,990, a $9,214 spread on the same certified stone. NZ Jewellers lists it at $16,990. 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.
