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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6391048315. Listed at 22 retailers, with prices from $7,738 to $15,735 at NZ Jewellers, a $7,997 spread on the same certified stone. 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.
