This 1.64ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG833604231 or 833604231. Listed at 6 retailers as of October 29, 2026, with prices from HK$4,841 to HK$25,736, a HK$20,895 spread on the same certified stone. Brilliant Earth lists it at HK$25,736. 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.
