This 1.51ct lab-grown marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG786694987 or 786694987. Listed at 6 retailers as of November 1, 2026, with prices from €225 to €1,079, a €855 spread on the same certified stone. Frank Darling lists it at €1,079.
