About this 1.31ct natural oval diamond

This 1.31ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2554026545. Listed at 17 retailers as of November 5, 2026, with prices from $3,246 to $8,092, a $4,846 spread on the same certified stone. NZ Jewellers lists it at $8,092. 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.
