About this 3.1ct lab-grown cushion diamond

This 3.1ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG694501775 or 694501775. Listed at 17 retailers as of October 29, 2026, with prices from HK$14,012 to HK$51,001, a HK$36,988 spread on the same certified stone. Taylor and Hart lists it at HK$51,001. 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.
