About this 0.82ct lab-grown cushion diamond

This 0.82ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816662489 or 816662489. Listed at 19 retailers as of November 1, 2026, with prices from $640 to $3,477, a $2,836 spread on the same certified stone. Diamond Exchange Canada lists it at $3,477. 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.
