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 1443981684. Listed at 6 retailers as of October 29, 2026, with prices from HK$2,488 to HK$8,001, a HK$5,513 spread on the same certified stone. MOH London lists it at HK$8,001. 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.
