About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2243094424. Listed at 10 retailers as of November 5, 2026, with prices from $5,542 to $12,603, a $7,061 spread on the same certified stone. NZ Jewellers lists it at $12,603. 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.
