About this 0.78ct lab-grown oval diamond

This 0.78ct lab-grown oval 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 LG797606779 or 797606779. Listed at 31 retailers as of November 2, 2026, with prices from $365 to $3,136, a $2,771 spread on the same certified stone. Do Amore Diamonds lists it at $3,136. 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.
