About this 0.71ct natural cushion diamond

This 0.71ct natural cushion sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1423092071. Listed at 13 retailers as of November 4, 2026, with prices from £554 to £1,360, a £805 spread on the same certified stone. MOH London lists it at £1,360. 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.
