About this 1.28ct lab-grown asscher diamond

This 1.28ct lab-grown asscher 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 LG836619954 or 836619954. Listed at 16 retailers as of November 1, 2026, with prices from HK$3,641 to HK$18,595, a HK$14,955 spread on the same certified stone. Brilliant Earth lists it at HK$18,595. 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.
