About this 0.73ct lab-grown round diamond

This 0.73ct lab-grown round 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 LG707550238 or 707550238. Listed at 21 retailers as of November 1, 2026, with prices from $300 to $1,948, a $1,648 spread on the same certified stone. Reve Diamonds lists it at $1,948. 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.
