This 1.05ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG621407925 or 621407925. Listed at 26 retailers as of November 4, 2026, with prices from $332 to $3,193, a $2,861 spread on the same certified stone. Do Amore Diamonds lists it at $3,193. 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.
