About this 0.45ct lab-grown emerald diamond

This 0.45ct lab-grown emerald sits in the sub-half-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG821621001 or 821621001. Listed at 3 retailers as of October 23, 2026, with prices from £261 to £532, a £271 spread on the same certified stone. Taylor and Hart lists it at £532. 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.
