About this 1.01ct natural marquise diamond

This 1.01ct 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 5231307178. Listed at 4 retailers as of November 1, 2026, with prices from £1,252 to £1,972, a £720 spread on the same certified stone. Yorxs lists it at £1,972. 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.
