About this 0.91ct lab-grown emerald diamond

This 0.91ct lab-grown emerald sits in the just-under-one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG583316392 or 583316392. Listed at 11 retailers as of November 2, 2026, with prices from £156 to £1,489, a £1,333 spread on the same certified stone. Do Amore Diamonds lists it at £1,489. 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.
