About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-carat band, graded H colour (near-colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1545998523. Listed at 11 retailers as of November 1, 2026, with prices from $1,796 to $4,848, a $3,052 spread on the same certified stone. NZ Jewellers lists it at $4,848. 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.
