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 IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG799618255 or 799618255. Listed at 14 retailers as of October 29, 2026, with prices from $142 to $1,380, a $1,238 spread on the same certified stone. Do Amore Diamonds lists it at $1,380. 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.
