This 1.23ct lab-grown round sits in the classic one-carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by GCAL 262000075. Listed at 4 retailers as of November 1, 2026, with prices from €344 to €999, a €655 spread on the same certified stone. MOH London lists it at €999.
