About this 0.86ct lab-grown radiant diamond

This 0.86ct lab-grown radiant sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818634134 or 818634134. Listed at 12 retailers, with a 281% 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.
