About this 1.09ct natural marquise diamond

This 1.09ct natural marquise sits in the classic one-carat band, graded I colour (near-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 3565660982. Listed at 8 retailers as of November 1, 2026, with prices from £3,418 to £6,082, a £2,664 spread on the same certified stone. MOH London lists it at £6,082. 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.
