About this 0.45ct lab-grown princess diamond

This 0.45ct 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 LG834601266 or 834601266. Listed at 12 retailers as of October 31, 2026, with prices from £311 to £1,457, a £1,146 spread on the same certified stone. Riddles Jewelry lists it at £1,457. 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.
