About this 1.43ct lab-grown cushion diamond

This 1.43ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831698104 or 831698104. Listed at 13 retailers as of November 1, 2026, with prices from HK$3,892 to HK$17,261, a HK$13,370 spread on the same certified stone. Brilliant Earth lists it at HK$17,261. 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.
