About this 0.31ct lab-grown round diamond

This 0.31ct lab-grown round sits in the sub-half-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG741573324 or 741573324. Listed at 16 retailers as of October 29, 2026, with prices from $128 to $1,302, a $1,174 spread on the same certified stone. MOH London lists it at $1,302. 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.
