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 standard cut grade stated by the retailer rather than the lab and certified by GIA 6562118709. Listed at 18 retailers as of October 30, 2026, with prices from $3,110 to $6,104, a $2,994 spread on the same certified stone. NZ Jewellers lists it at $6,104. 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.
