About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6442476795. Listed at 8 retailers as of October 28, 2026, with prices from £8,767 to £11,662, a £2,895 spread on the same certified stone. Jared lists it at £11,662. 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.
