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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2231779824. Listed at 8 retailers as of October 29, 2026, with prices from HK$4,245 to HK$9,097, a HK$4,853 spread on the same certified stone. MOH London lists it at HK$9,097. 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.
