About this 0.31ct natural cushion diamond

This 0.31ct 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 2556419776. Listed at 9 retailers as of October 29, 2026, with prices from HK$3,178 to HK$6,806, a HK$3,628 spread on the same certified stone. MOH London lists it at HK$6,806. 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.
