About this 4.08ct lab-grown cushion diamond

This 4.08ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG735516175 or 735516175. Listed at 19 retailers as of October 30, 2026, with prices from HK$26,887 to HK$90,708, a HK$63,821 spread on the same certified stone. Taylor and Hart lists it at HK$90,708. 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.
