About this 0.7ct natural marquise diamond

This 0.7ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5556345251. Listed at 10 retailers as of November 1, 2026, with prices from £580 to £1,311, a £731 spread on the same certified stone. MOH London lists it at £1,311. 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.
