About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded M 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 2241005149. Listed at 8 retailers as of November 4, 2026, with prices from £1,122 to £2,217, a £1,096 spread on the same certified stone. Wholesale Diamonds Direct lists it at £2,217. 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.
