About this 1ct natural oval diamond

This 1ct 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 2556153700. Listed at 21 retailers as of November 1, 2026, with prices from $1,062 to $4,448, a $3,386 spread on the same certified stone. NZ Jewellers lists it at $4,448. 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.
