About this 0.83ct natural cushion diamond

This 0.83ct natural cushion sits in the just-under-one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2534956149. Listed at 4 retailers as of October 30, 2026, with prices from £381 to £559, a £178 spread on the same certified stone. Ritani lists it at £559. 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.
