About this 0.4ct natural cushion diamond
This 0.4ct natural cushion sits in the sub-half-carat band, graded J 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 5536810732. Listed at 10 retailers as of October 29, 2026, with prices from €437 to €890, a €453 spread on the same certified stone. MOH London lists it at €890. 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.
