About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1423043483. Listed at 17 retailers as of October 30, 2026, with prices from $10,115 to $18,102, a $7,987 spread on the same certified stone. NZ Jewellers lists it at $18,102. 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.
