About this 0.4ct natural cushion diamond

This 0.4ct natural cushion sits in the sub-half-carat band, graded G 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 1555403296. Listed at 13 retailers as of October 27, 2026, with prices from HK$3,506 to HK$7,781, a HK$4,275 spread on the same certified stone. MOH London lists it at HK$7,781. 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.
