About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7566655106. Listed at 23 retailers as of November 5, 2026, with prices from $3,588 to $7,841, a $4,253 spread on the same certified stone. NZ Jewellers lists it at $7,841. 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.
