This 1.05ct lab-grown radiant sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included) and certified by IGI LG636492174 or 636492174. Listed at 2 retailers as of November 5, 2026, with prices from $537 to $647, a $110 spread on the same certified stone. MD Diamonds and Jewellers lists it at $647. 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.
