About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded I 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 6561357470. Listed at 21 retailers as of October 28, 2026, with prices from $9,061 to $19,500, a $10,439 spread on the same certified stone. NZ Jewellers lists it at $19,500. 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.
