About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded J 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 2546866306. Listed at 21 retailers as of October 30, 2026, with prices from $6,082 to $13,973, a $7,890 spread on the same certified stone. NZ Jewellers lists it at $13,973. 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.
