About this 1.64ct lab-grown cushion diamond

This 1.64ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG826606966 or 826606966. Listed at 17 retailers as of October 30, 2026, with prices from HK$4,150 to HK$17,237, a HK$13,087 spread on the same certified stone. Brilliance lists it at HK$17,237. 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.
