About this 1ct lab-grown cushion diamond

This 1ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG688518345 or 688518345. Listed at 11 retailers as of October 30, 2026, with prices from €314 to €1,577, a €1,263 spread on the same certified stone. Taylor and Hart lists it at €1,577. 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.
