About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 816642645. Listed at 17 retailers as of October 30, 2026, with prices from $1,746 to $5,670, a $3,924 spread on the same certified stone. NZ Jewellers lists it at $5,670. 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.
