This 1.51ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG506191309 or 506191309. Listed at 12 retailers as of November 4, 2026, with a 201% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface.
