This 1.45ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG616402643 or 616402643. Listed at 11 retailers as of October 27, 2026, with prices from £128 to £1,230, a £1,101 spread on the same certified stone. Do Amore Diamonds lists it at £1,230. 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.
