About this 0.73ct lab-grown round diamond

This 0.73ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG805658330 or 805658330. Listed at 9 retailers as of October 29, 2026, with prices from $534 to $1,622, a $1,088 spread on the same certified stone. MOH London lists it at $1,622. 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.
