This 1.61ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG665402345 or 665402345. Listed at 10 retailers as of October 30, 2026, with prices from £324 to £1,709, a £1,385 spread on the same certified stone. Do Amore Diamonds lists it at £1,709. 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.
