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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 5566421584. Listed at 18 retailers as of November 4, 2026, with prices from $2,432 to $5,613, a $3,181 spread on the same certified stone. NZ Jewellers lists it at $5,613. 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.
