This 3.78ct lab-grown oval sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830677220 or 830677220. Listed at 8 retailers as of October 29, 2026, with prices from HK$5,423 to HK$20,705, a HK$15,282 spread on the same certified stone. MOH London lists it at HK$20,705. 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.
