You won’t find them in the glitzy shops on Laugavegur (Laundry Road) in Reykjavik, but if you go out to the Fossá (The River of the Falls), right where it empties into the Sélvallavatn (Lake in the Valley of the Seals) in the Berserkjahraun (The Berserker Lava Field), you might.

See them? No? That’s because you have to stomp down through the drifts in the wind and get down on your hands and knees beside the river, just before it touches the frozen lakeshore. See them? Under the goofy elf sheep of snow?

No? Then closer, it is. (Aren’t pearls worth it?)

Just like shark teeth.
