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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2246218892. Listed at 10 retailers as of October 31, 2026, with prices from HK$5,234 to HK$8,714, a HK$3,480 spread on the same certified stone. 77 Diamonds lists it at HK$8,714. 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.
