About this 3.17ct lab-grown cushion diamond

This 3.17ct lab-grown 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. Listed at 4 retailers as of November 6, 2026, with prices from HK$8,856 to HK$39,446, a HK$30,589 spread on the same certified stone. Washington Diamond lists it at HK$39,446. 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.
