About this 1ct lab-grown cushion diamond

This 1ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG839620617 or 839620617. Listed at 5 retailers as of November 6, 2026, with prices from HK$1,505 to HK$6,374, a HK$4,870 spread on the same certified stone. Frank Darling lists it at HK$6,374. 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.
