About this 0.4ct natural cushion diamond

This 0.4ct natural cushion sits in the sub-half-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1508431975. Listed at 9 retailers as of November 1, 2026, with prices from HK$2,432 to HK$5,411, a HK$2,978 spread on the same certified stone. MOH London lists it at HK$5,411. 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.
