About this 0.45ct lab-grown cushion diamond

This 0.45ct lab-grown cushion sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG680582058 or 680582058. Listed at 14 retailers as of October 29, 2026, with prices from $325 to $1,604, a $1,278 spread on the same certified stone. MOH London lists it at $1,604. 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.
