About this 0.55ct lab-grown princess diamond

This 0.55ct lab-grown princess sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG678579669 or 678579669. Listed at 21 retailers as of October 30, 2026, with prices from £125 to £812, a £687 spread on the same certified stone. Reve Diamonds lists it at £812. 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.
