This 1ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 808619731. Listed at 15 retailers as of November 5, 2026, with prices from $1,830 to $4,295, a $2,465 spread on the same certified stone. NZ Jewellers lists it at $4,295. 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.
