About this 0.65ct lab-grown cushion diamond

This 0.65ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816662419 or 816662419. Listed at 15 retailers as of November 3, 2026, with prices from $455 to $2,438, a $1,983 spread on the same certified stone. Kay Jewelers lists it at $2,438. 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.
