About this 0.4ct natural cushion diamond

This 0.4ct natural cushion sits in the sub-half-carat band, graded F 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 5523856401. Listed at 10 retailers as of November 1, 2026, with prices from HK$4,433 to HK$9,984, a HK$5,551 spread on the same certified stone. MOH London lists it at HK$9,984. 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.
