About this 3.91ct lab-grown oval diamond

This 3.91ct lab-grown oval sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG786603259 or 786603259. Listed at 7 retailers as of October 29, 2026, with prices from HK$4,692 to HK$35,800, a HK$31,108 spread on the same certified stone. Frank Darling lists it at HK$35,800. 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.
