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 standard cut grade stated by the retailer rather than the lab and certified by GIA 7471301378. Listed at 22 retailers as of October 27, 2026, with prices from $6,597 to $14,869, a $8,272 spread on the same certified stone. NZ Jewellers lists it at $14,869. 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.
