This 4.01ct lab-grown oval sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG836627786 or 836627786. Listed at 14 retailers as of October 30, 2026, with prices from HK$3,701 to HK$23,303, a HK$19,602 spread on the same certified stone. Brilliant Earth lists it at HK$23,303. 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.
