About this 3.07ct lab-grown emerald diamond

This 3.07ct lab-grown emerald sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2506644404. Listed at 4 retailers as of November 4, 2026, with prices from £1,285 to £2,905, a £1,620 spread on the same certified stone. Zales lists it at £2,905. 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.
