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 1242091271. Listed at 21 retailers as of November 5, 2026, with prices from $3,094 to $8,408, a $5,314 spread on the same certified stone. NZ Jewellers lists it at $8,408. 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.
