About this 0.9ct lab-grown princess diamond

This 0.9ct lab-grown princess 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 LG847690172 or 847690172. Listed at 17 retailers as of October 29, 2026, with prices from £273 to £1,146, a £873 spread on the same certified stone. Riddles Jewelry lists it at £1,146. 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.
