About this 0.5ct lab-grown round diamond

This 0.5ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818658679 or 818658679. Listed at 18 retailers as of October 28, 2026, with a 583% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
