About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552587612. Listed at 20 retailers as of November 4, 2026, with prices from $2,278 to $5,276, a $2,998 spread on the same certified stone. NZ Jewellers lists it at $5,276. 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.
