About this 1ct natural marquise diamond

This 1ct natural marquise 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 6561386222. Listed at 21 retailers as of November 1, 2026, with prices from $3,427 to $7,947, a $4,521 spread on the same certified stone. NZ Jewellers lists it at $7,947. 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.
