This 1.01ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG816607704 or 816607704. Listed at 8 retailers as of October 29, 2026, with prices from HK$2,464 to HK$9,640, a HK$7,176 spread on the same certified stone. Reve Diamonds lists it at HK$9,640. 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.
