About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6445544770. Listed at 20 retailers as of October 31, 2026, with prices from $2,390 to $6,885, a $4,495 spread on the same certified stone. NZ Jewellers lists it at $6,885. 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.
