About this 1.6ct lab-grown cushion diamond

This 1.6ct lab-grown cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GCAL 310320003. Listed at 3 retailers as of October 31, 2026, with prices from £459 to £1,866, a £1,407 spread on the same certified stone. Do Amore Diamonds lists it at £1,866. 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.
