About this 0.51ct lab-grown emerald diamond

This 0.51ct lab-grown emerald sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG807644686 or 807644686. Listed at 20 retailers as of October 26, 2026, with prices from $198 to $1,157, a $959 spread on the same certified stone. MOH London lists it at $1,157. 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.
