About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded H 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 5241084054. Listed at 22 retailers as of November 5, 2026, with prices from $6,676 to $15,200, a $8,524 spread on the same certified stone. NZ Jewellers lists it at $15,200. 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.
