About this 0.91ct lab-grown oval diamond

This 0.91ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG617450023 or 617450023. Listed at 25 retailers as of October 26, 2026, with prices from £116 to £1,502, a £1,385 spread on the same certified stone. Do Amore Diamonds lists it at £1,502. 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.
