About this 0.3ct lab-grown princess diamond

This 0.3ct 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 LG833658510 or 833658510. Listed at 15 retailers as of October 29, 2026, with prices from £243 to £1,307, a £1,064 spread on the same certified stone. MOH London lists it at £1,307. 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.
