About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7421714067. Listed at 21 retailers as of October 30, 2026, with prices from $4,542 to $10,908, a $6,366 spread on the same certified stone. NZ Jewellers lists it at $10,908. 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.
