About this 0.51ct lab-grown oval diamond

This 0.51ct lab-grown oval 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 LG811660842 or 811660842. Listed at 18 retailers as of October 26, 2026, with prices from $146 to $983, a $837 spread on the same certified stone. Michael Trio lists it at $983. 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.
