A compact octagon-cut Nigerian emerald with a pale, icy blue-green tone and an expressive jardin. The step-cut facets open up a clear view into the stone's interior, where a rich landscape of fractures and feathers creates genuine natural texture throughout. The very light color gives the stone a soft, translucent quality - think frosted sea glass with green overtones - rather than a deep saturated tone, which has its own gentle charm.
This is a stone for those who appreciate the inner life of an emerald as much as the surface color. Lightly oiled as standard. The octagon cut suits mounting in a bezel setting where the step facets can really show. Despite its modest size, it carries plenty of natural character. Nigerian origin. Sold as a single loose stone.
Natural Nigerian emerald, May birthstone - sold loose.

About emerald
Emerald is the green variety of beryl. It is 7.5 to 8 on the Mohs scale, but almost every emerald has natural fractures, and most are clarity-enhanced with oil or resin, so it is more fragile than its hardness suggests.
Cleaning
Warm water, a drop of mild dish soap and a soft toothbrush are all you need. Brush behind the stone too, where dust and skin oils collect, then rinse and dry with a soft cloth. Skip ultrasonic and steam cleaners: they can drive out the oil or resin most emeralds carry in their fractures, and open the fractures themselves. Keep solvents, alcohol and jewelry cleaners away from it for the same reason.
Wear and storage
A sharp knock against stone or metal can still chip an emerald, most often at the thin edges and points. Store it on its own in a gem jar or a soft pouch: it scratches softer gems, and topaz, sapphire and diamond can scratch it.
For your jeweler
This emerald is clarity-enhanced with oil, as is usual for emerald. Emerald should be kept away from the torch flame, acid pickle and the ultrasonic bath. Re-oiling is a normal service if a fracture becomes more visible over time.
