This 3.12ct lab-grown oval sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG844602149 or 844602149. Listed at 19 retailers as of October 29, 2026, with prices from HK$7,226 to HK$69,662, a HK$62,436 spread on the same certified stone. Blue Nile lists it at HK$69,662. 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.
