About this 0.4ct natural cushion diamond

This 0.4ct natural cushion sits in the sub-half-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558384159. Listed at 11 retailers as of October 27, 2026, with prices from HK$3,373 to HK$7,474, a HK$4,100 spread on the same certified stone. MOH London lists it at HK$7,474. 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.
