About this 0.78ct lab-grown radiant diamond

This 0.78ct lab-grown radiant sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG728558160 or 728558160. Listed at 23 retailers as of October 30, 2026, with prices from $252 to $2,749, a $2,497 spread on the same certified stone. Do Amore Diamonds lists it at $2,749. 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.
