About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5553373107. Listed at 9 retailers as of November 4, 2026, with prices from £1,217 to £2,404, a £1,187 spread on the same certified stone. Wholesale Diamonds Direct lists it at £2,404. 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.
