About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2438239024. Listed at 19 retailers as of October 30, 2026, with prices from $8,940 to $20,147, a $11,207 spread on the same certified stone. NZ Jewellers lists it at $20,147. 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.
