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 very-good cut grade and certified by IGI 774635679. Listed at 15 retailers as of November 5, 2026, with prices from $2,259 to $6,050, a $3,791 spread on the same certified stone. NZ Jewellers lists it at $6,050. 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.
