This 3.1ct lab-grown marquise sits in the three to five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839686821 or 839686821. Listed at 11 retailers as of November 1, 2026, with prices from HK$4,221 to HK$23,302, a HK$19,081 spread on the same certified stone. Brilliant Earth lists it at HK$23,302. 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.
