About this 0.51ct lab-grown round diamond
This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG639448988 or 639448988. Listed at 17 retailers as of November 1, 2026, with prices from $119 to $1,231, a $1,112 spread on the same certified stone. MOH London lists it at $1,231. 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.
