About this 0.67ct lab-grown round diamond

This 0.67ct lab-grown round 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 LG786651466 or 786651466. Listed at 20 retailers as of October 29, 2026, with prices from £137 to £1,179, a £1,043 spread on the same certified stone. Do Amore Diamonds lists it at £1,179. 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.
