About this 0.73ct lab-grown marquise diamond

This 0.73ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG800638180 or 800638180. Listed at 25 retailers as of November 1, 2026, with a 518% 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.
