About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561367204. Listed at 24 retailers as of November 5, 2026, with prices from $4,302 to $9,921, a $5,619 spread on the same certified stone. NZ Jewellers lists it at $9,921. 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.
