This 0.99ct 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 LG831688151 or 831688151. Listed at 7 retailers as of October 29, 2026, with prices from HK$3,601 to HK$10,223, a HK$6,622 spread on the same certified stone. MOH London lists it at HK$10,223. 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.
