This 0.51ct lab-grown cushion sits in the half to three-quarter carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG620495325 or 620495325. Listed at 6 retailers as of November 2, 2026, with prices from HK$2,157 to HK$10,850, a HK$8,693 spread on the same certified stone. MOH London lists it at HK$10,850. 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.
