This ring has a lot going on, I feel the pictures do it justice, but I'll elaborate below on some of the more technical details:
First: Yes, the gears do move and interact with each other. That being said, the movement is stiff and a bit jerky.
Materials:The entire ring is crafted in sterling silver, and each gear is shaped from yellow brass.
The overall size of the top of the ring is 38mm long (1.5")There are a total of 17 gemstones in this ring.
They are each identified on the last picture. Here is that information again:
Black Diamond (1) at 5.0mm, AAA Grade, 0.65 carats (65 points)
Sapphires (6) at 2.5-2.6mm each along the outer rim. These range from A grade to AAA Grade. One of them has Ceylon color.
Sapphire (1) at 3.0mm,
AA GradeRubies (2) at 2.5-2.6mm each,

Chocolate Diamond (1) at 1.5mm, I1 clarity
Blue Diamond (2) at 1.0 - 1.1mm each, SI/3-I-1 clarity,Aqua Blue color
All of these are natural stones (earth mined). This ring, will always be one of a kind.
