About this 4.27ct lab-grown emerald diamond

This 4.27ct lab-grown emerald sits in the three to five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1528064507. Listed at 16 retailers, with a 274% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Lab-grown prices in the 2ct and up range have fallen 40 to 60% over the last 18 months. Use the cross-retailer spread above to find the lowest current listing.
