This 1.23ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG612329242 or 612329242. Listed at 18 retailers as of November 4, 2026, with prices from $206 to $1,760, a $1,554 spread on the same certified stone. Do Amore Diamonds lists it at $1,760. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
