Adjustable size fossil shark tooth and .950 fine sterling silver ring by Chalres Albert. This ring can be adjusted from around size 5 to around size 10. The band is 5mm wide and holds its size well once adjusted to the desired size. It wraps around the finger and bypasses itself underneath the setting (shown in the alternate photo). The shark tooth is around 3/4" long by around 5/8" wide on average. The exact color and measurements of the shark tooth will vary slightly from the sample photos with each ring. Each ring includes a card about the fossil and comes packaged in a jewelry box.
