About this 1.45ct lab-grown radiant diamond

This 1.45ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG846663227 or 846663227. Listed at 8 retailers as of October 30, 2026, with prices from HK$3,052 to HK$26,675, a HK$23,623 spread on the same certified stone. Brilliant Earth lists it at HK$26,675. 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.
