About this 1.01ct lab-grown cushion diamond

This 1.01ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831690477 or 831690477. Listed at 11 retailers as of October 30, 2026, with prices from HK$3,011 to HK$14,318, a HK$11,307 spread on the same certified stone. Helzberg Diamonds lists it at HK$14,318. 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.
