About this 0.78ct lab-grown round diamond

This 0.78ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG831641255 or 831641255. Listed at 6 retailers as of October 28, 2026, with prices from £128 to £969, a £841 spread on the same certified stone. Do Amore Diamonds lists it at £969. 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.
