About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566065338. Listed at 20 retailers as of November 5, 2026, with prices from £1,836 to £4,318, a £2,483 spread on the same certified stone. NZ Jewellers lists it at £4,318. 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.
