About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5386649666. Listed at 16 retailers as of November 5, 2026, with prices from $1,120 to $3,879, a $2,759 spread on the same certified stone. NZ Jewellers lists it at $3,879. 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.
