Material

An Armillary Sphere is an ancient astronomical device, originating from China in the 4th century BC and Greece in the 3rd century BC. It depicts the positions of celestial objects in the sky. The pendant is based on the Ptolemaic armillary sphere, placing Earth at the center, in contrast to the Copernican armillary sphere, where the Sun is at the center. One complete rotation of the central axis of the Ptolemaic armillary sphere represents 24 hours. The three narrow central bands correspond to the equatorial ring, the Tropic of Cancer and the Tropic of Capricorn. The wider band wrapping around the set of three is the ecliptic ring, representing the signs of the zodiac and the annual path of the sun.

The Armillary Sphere Pendant is approximately 2.5 cm (1 inch) in diameter. The central axis rotates inside the two exterior rings.

The pendant is 3D printed in interlocking solid sterling silver or polished brass, finished with a 45 cm/18 inch long sterling silver or gold plated silver chain, and is ready for gift giving with a gift box, polishing cloth, and care instructions.

Could do better!

The pendant was very beautiful when I received it: a very beautiful golden color and a beautiful shine...
I immediately put it around my neck.
Unfortunately, in just a few hours, it became dull and without shine...
So, I think it's brass alloy and brass oxidizes in air... it can even end up taking on a greenish tint, I read... Obviously, in contact with the skin, it's worse...
So, I admit that I'm quite disappointed. I think that for the price, it could have been gold plated.

So… I'm going to clean it and have it gold plated, myself. It's going to cost me a little money but if I don't do anything, I won't wear the jewelry anymore and it's quite a lot of money for something that I only wore for 24 hours...
