About this 1.24ct natural marquise diamond

This 1.24ct natural marquise sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6542876559. Listed at 4 retailers as of November 6, 2026, with prices from £4,255 to £5,348, a £1,093 spread on the same certified stone. 77 Diamonds lists it at £5,348. 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.
