About this 0.43ct lab-grown princess diamond

This 0.43ct lab-grown princess sits in the sub-half-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG831629010 or 831629010. Listed at 12 retailers as of October 30, 2026, with prices from €358 to €1,550, a €1,192 spread on the same certified stone. Riddles Jewelry lists it at €1,550. 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.
