About this 1.55ct lab-grown cushion diamond

This 1.55ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG642469463 or 642469463. Listed at 11 retailers as of October 28, 2026, with prices from HK$3,609 to HK$9,526, a HK$5,917 spread on the same certified stone. Brilliance lists it at HK$9,526. 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.
