About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1418729047. Listed at 17 retailers as of November 5, 2026, with prices from $2,697 to $7,890, a $5,193 spread on the same certified stone. NZ Jewellers lists it at $7,890. 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.
