About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555434609. Listed at 6 retailers as of October 31, 2026, with prices from £1,843 to £2,202, a £359 spread on the same certified stone. Blue Nile lists it at £2,202. 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.
