About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-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 2556985857. Listed at 14 retailers as of November 5, 2026, with prices from $1,618 to $4,678, a $3,060 spread on the same certified stone. NZ Jewellers lists it at $4,678. 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.
