About this 1.01ct natural marquise diamond

This 1.01ct 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 stated by the retailer rather than the lab and certified by GIA 6555036262. Listed at 18 retailers as of November 5, 2026, with prices from £1,973 to £4,099, a £2,126 spread on the same certified stone. NZ Jewellers lists it at £4,099. 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.
