About this 0.39ct natural cushion diamond

This 0.39ct natural cushion sits in the sub-half-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5232479799. Listed at 4 retailers as of October 29, 2026, with prices from £351 to £709, a £358 spread on the same certified stone. MOH London lists it at £709. 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.
