About this 1.04ct lab-grown cushion diamond

This 1.04ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818662298 or 818662298. Listed at 14 retailers as of November 4, 2026, with prices from HK$4,707 to HK$12,318, a HK$7,610 spread on the same certified stone. Brilliant Earth lists it at HK$12,318. 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.
