About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG605396510 or 605396510. Listed at 20 retailers as of October 30, 2026, with prices from HK$1,671 to HK$18,516, a HK$16,845 spread on the same certified stone. Brilliant Earth lists it at HK$18,516. 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.
