About this 0.59ct lab-grown marquise diamond

This 0.59ct lab-grown marquise 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 LG807610393 or 807610393. Listed at 21 retailers as of October 26, 2026, with a 454% 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.
