About this 0.4ct natural cushion diamond

This 0.4ct natural cushion sits in the sub-half-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5233524962. Listed at 8 retailers as of October 31, 2026, with prices from HK$5,100 to HK$6,738, a HK$1,638 spread on the same certified stone. DreamStone lists it at HK$6,738. 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.
