About this 0.5ct natural cushion diamond

This 0.5ct natural cushion sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551726923. Listed at 13 retailers as of October 27, 2026, with prices from HK$2,691 to HK$12,904, a HK$10,213 spread on the same certified stone. Queensmith lists it at HK$12,904. 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.
