About this 3.5ct natural cushion diamond

This 3.5ct natural cushion sits in the three to five 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 1242003490. Listed at 11 retailers as of November 6, 2026, with prices from HK$228,147 to HK$394,104, a HK$165,957 spread on the same certified stone. Diamonds Direct lists it at HK$394,104. 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.
