This 2.57ct lab-grown radiant sits in the two to three carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included) and certified by IGI LG784683977 or 784683977. Listed at 24 retailers as of October 29, 2026, with prices from HK$3,264 to HK$30,601, a HK$27,337 spread on the same certified stone. Brilliant Earth lists it at HK$30,601. 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.
