I made this pair of earrings up over the weekend and they have some unusual gem materials in them. I had the opportunity recently to purchase some Montana sapphires (yes they come from Montana!) from the collection of Henry Shawah, a wonderful local jeweler who passed away about a year ago. Blue Montana sapphires usually have a very different type of blue color than most other sapphires. They tend to be somewhat lighter in color, with slight green overtones and usually accent someone with blue eyes wonderfully, because the tone is closer to that in the eye color. But.....they sold yesterday so if your sweetie has blue eyes we'll have to look at some other stone options........
