About this 0.91ct lab-grown marquise diamond

This 0.91ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG799697369 or 799697369. Listed at 19 retailers as of November 1, 2026, with a 506% 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.
