About this 0.66ct lab-grown round diamond

This 0.66ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG831659834 or 831659834. Listed at 24 retailers as of October 31, 2026, with prices from $162 to $1,220, a $1,058 spread on the same certified stone. Do Amore Diamonds lists it at $1,220. 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.
