This 1ct lab-grown asscher sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840617138 or 840617138. Listed at 13 retailers as of November 3, 2026, with prices from HK$3,578 to HK$20,870, a HK$17,292 spread on the same certified stone. Brilliant Earth lists it at HK$20,870. 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.
