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 VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2437639876. Listed at 20 retailers as of November 1, 2026, with prices from $12,514 to $28,799, a $16,285 spread on the same certified stone. NZ Jewellers lists it at $28,799. 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.
