About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5563549701. Listed at 15 retailers as of November 4, 2026, with prices from £2,398 to £4,562, a £2,164 spread on the same certified stone. Helzberg Diamonds lists it at £4,562. 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.
