This 0.7ct lab-grown radiant sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG566394115 or 566394115. Listed at 17 retailers as of October 30, 2026, with prices from $127 to $1,220, a $1,093 spread on the same certified stone. Do Amore Diamonds lists it at $1,220. 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.
