About this 0.73ct lab-grown radiant diamond

This 0.73ct lab-grown radiant sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG634449755 or 634449755. Listed at 19 retailers as of October 30, 2026, with prices from $300 to $2,878, a $2,577 spread on the same certified stone. Do Amore Diamonds lists it at $2,878. 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.
