This 1.15ct lab-grown radiant sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG634413023 or 634413023. Listed at 15 retailers as of November 1, 2026, with prices from $279 to $1,590, a $1,311 spread on the same certified stone. Do Amore Diamonds lists it at $1,590. 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.
