This 0.3ct lab-grown cushion sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816662421 or 816662421. Listed at 12 retailers as of November 4, 2026, with prices from HK$1,491 to HK$10,542, a HK$9,051 spread on the same certified stone. MOH London lists it at HK$10,542. 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.
