In North America, not many superlative gemstones are mined that are on par with locations such as Burma, India, Brazil or Colombia. But one notable exception is Montana sapphires.

Exuding a special hue unlike those from any other region, their clear, lilac blue and bright hues are unmistakable. The mines that once produced these beauties are no longer in operation.

In 14k gold, the elongated crescent moon is set with 11 round, faceted natural sapphires. Their total carat weight adds up to 1.65 carats of colorific vibrancy.

Each is paired with a white, cultured half pearl. Likely converted from a brooch, a gold rolo chain has been added to make this into a divine necklace.

Note: The Yogo mine in Montana started production in 1895. most of the gemstones unearthed were small. Operating until 1929, most of the jewelry produced using these sapphires dates to these years. Since then, its history of operations has been sporadic, with several attempts to open it again with little long-term success.

Other adjacent mines opened and shut as well. The complexity of the geology of these veins, and the small size of most of the sapphires found, along with other difficulties, means that Montana sapphires are scarce and desirable.
