About this 1.42ct lab-grown asscher diamond

This 1.42ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG591368505 or 591368505. Listed at 14 retailers as of November 1, 2026, with prices from HK$3,986 to HK$20,752, a HK$16,766 spread on the same certified stone. Rare Carat lists it at HK$20,752. 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.
