About this 0.48ct lab-grown oval diamond

This 0.48ct lab-grown oval sits in the sub-half-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG828616340 or 828616340. Listed at 15 retailers as of October 31, 2026, with a 328% 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.
