This 1.01ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG831623991 or 831623991. Listed at 15 retailers as of October 28, 2026, with prices from HK$1,428 to HK$11,260, a HK$9,832 spread on the same certified stone. Queensmith lists it at HK$11,260. 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.
