This 0.91ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG457056543 or 457056543. Listed at 12 retailers as of October 26, 2026, with prices from €124 to €717, a €594 spread on the same certified stone. MOH London lists it at €717.
