About this 1.03ct natural marquise diamond

This 1.03ct 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 1549865080. Listed at 7 retailers as of November 1, 2026, with prices from £1,822 to £3,435, a £1,613 spread on the same certified stone. With Clarity lists it at £3,435. 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.
