About this 0.97ct lab-grown radiant diamond

This 0.97ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817670921 or 817670921. Listed at 21 retailers as of November 2, 2026, with prices from HK$1,381 to HK$9,494, a HK$8,113 spread on the same certified stone. Brilliant Earth lists it at HK$9,494. 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.
