This 0.78ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG752509596 or 752509596. Listed at 4 retailers as of October 31, 2026, with prices from HK$5,123 to HK$6,826, a HK$1,703 spread on the same certified stone. Kay Jewelers lists it at HK$6,826. 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.
