About this 0.73ct lab-grown round diamond

This 0.73ct lab-grown round sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG800684804 or 800684804. Listed at 16 retailers as of October 31, 2026, with prices from £135 to £1,299, a £1,164 spread on the same certified stone. Do Amore Diamonds lists it at £1,299. 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.
