This 1.21ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG550227491 or 550227491. Listed at 14 retailers as of November 1, 2026, with prices from HK$1,436 to HK$7,453, a HK$6,017 spread on the same certified stone. MOH London lists it at HK$7,453. 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.
