About this 1.38ct lab-grown round diamond

This 1.38ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG841631803 or 841631803. Listed at 4 retailers as of October 31, 2026, with prices from £260 to £1,246, a £987 spread on the same certified stone. Brilliant Earth lists it at £1,246. 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.
