About this 0.57ct lab-grown cushion diamond

This 0.57ct 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 LG678542302 or 678542302. Listed at 21 retailers as of November 3, 2026, with prices from $463 to $3,974, a $3,511 spread on the same certified stone. Do Amore Diamonds lists it at $3,974. 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.
