The pendant is articulated and measures approximately 1.5" overall. The well carved and detailed cameo is 9/16" in diameter including the rope frame. The features are nicely done with mustache and beard plus feathers on the helmet and outline of his breastplate.

Included is a delicate 10k Gold chain, approximately 18" long. Chain is newer than the pendant which dates from around 1900's.

Both carefully tested, pendant is marked 10K and OB for Ostby & Barton on the bail. Chain is marked on the chain tag.

Ostby & Barton were the foremost fine jewelry producers at the turn of the 20th Century. Mr. Ostby traveled the globe every year to hand pick the gems used in their designs. In one fateful trip, he perished as a passenger of the Titanic. Their jewelry is very desirable. Cameos, pendants and necklaces are the hardest to find.

We measure bracelets based on their wearable length, not the actual length. We do this because chunky bracelets will have a smaller wearable length than the actual length as the thickness of the bracelet reduces the internal measurement. If at any time you would like the actual length and is not in the description, please feel free to contact us.
