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 5, 2026, with prices from $3,181 to $7,368, a $4,187 spread on the same certified stone. NZ Jewellers lists it at $7,368. 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.
