About this 0.51ct lab-grown oval diamond

This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG536206340 or 536206340. Listed at 6 retailers as of November 1, 2026, with prices from $431 to $1,163, a $732 spread on the same certified stone. MOH London lists it at $1,163. 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.
