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 LG780665591 or 780665591. Listed at 16 retailers as of October 29, 2026, with prices from $253 to $2,431, a $2,178 spread on the same certified stone. Do Amore Diamonds lists it at $2,431. 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.
