As you can see, "Sea Shell #2" is a set of shells. And although most of the shells in this series will not necessarily resemble a particular kind of shell, these two are obviously abalone, for which the Northern California coast is quite well known. Though the shells may look a little delicate, especially since both of them are "chipped", they're more robust than they appear, and the wood grain on the concave sides in contrast to the convex blue make the pair quite stunning.
(Please note that the dimensions listed are for the larger of the two shells. The smaller shell is about 3/4" shorter in length.)
As with all of the pieces in the Sea Shell series, the driftwood itself, painted & unpainted, is treated with a proprietary blend of soy wax & natural pine tree turpentine (which is odorless after mixing with the soy wax) to help protect the wood and lend a subtle sheen. Moreover, each shell is not necessarily based on an actual type of shell, but is usually meant to be a bit abstract. Furthermore, each shell is made to appear just as it would when washed-up on the beach, that is, imperfect, and so any chips or missing bits are actually quite deliberate. And lastly, because each piece is so unique in size and shape and color and weight, they are all intended to be held as much as seen.
