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 LG834601267 or 834601267. Listed at 17 retailers as of October 31, 2026, with prices from £249 to £1,293, a £1,044 spread on the same certified stone. Riddles Jewelry lists it at £1,293. 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.
