About this 0.4ct natural cushion diamond

This 0.4ct natural cushion sits in the sub-half-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552694049. Listed at 14 retailers as of November 1, 2026, with prices from HK$4,825 to HK$10,891, a HK$6,066 spread on the same certified stone. MOH London lists it at HK$10,891. 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.
