About this 0.4ct natural emerald diamond

This 0.4ct natural emerald sits in the sub-half-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1242073831. Listed at 5 retailers as of October 28, 2026, with prices from £630 to £1,220, a £590 spread on the same certified stone. MOH London lists it at £1,220. 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.
