About this 0.4ct natural cushion diamond

This 0.4ct natural cushion sits in the sub-half-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5536810732. Listed at 9 retailers as of November 2, 2026, with prices from HK$3,865 to HK$7,762, a HK$3,897 spread on the same certified stone. MOH London lists it at HK$7,762. 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.
