About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2567186299. Listed at 8 retailers as of November 5, 2026, with prices from $8,370 to $18,041, a $9,671 spread on the same certified stone. NZ Jewellers lists it at $18,041. 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.
