About this 2ct natural marquise diamond

This 2ct natural marquise sits in the two to three carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1565629325. Listed at 5 retailers as of November 5, 2026, with prices from £6,498 to £8,145, a £1,647 spread on the same certified stone. Blue Nile lists it at £8,145. 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.
