About this 0.42ct lab-grown cushion diamond

This 0.42ct lab-grown cushion sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG680582004 or 680582004. Listed at 17 retailers as of October 26, 2026, with prices from $119 to $1,114, a $995 spread on the same certified stone. MOH London lists it at $1,114. 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.
