About this 0.4ct natural cushion diamond

This 0.4ct natural cushion sits in the sub-half-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1385543417. Listed at 10 retailers as of November 7, 2026, with prices from HK$3,151 to HK$10,013, a HK$6,863 spread on the same certified stone. MOH London lists it at HK$10,013. 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.
