About this 0.43ct lab-grown cushion diamond

This 0.43ct lab-grown cushion sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG743538660 or 743538660. Listed at 12 retailers as of November 4, 2026, with prices from HK$1,922 to HK$10,356, a HK$8,434 spread on the same certified stone. Kay Jewelers lists it at HK$10,356. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
