December Birthstone Rings in Sterling Silver
December birthstone rings feature three distinct gems: turquoise, tanzanite, and blue zircon. Each stone carries its own mineral composition and color range. Turquoise forms in arid regions where copper-rich groundwater interacts with aluminum and phosphorus. Tanzanite occurs in a single location near Mount Kilimanjaro. Blue zircon, not to be confused with cubic zirconia, is a natural mineral prized for its fire and brilliance. Our collection of 36,638 rings pairs these December stones with .925 sterling silver settings, priced from $6 to $6,302.

Turquoise, Tanzanite & Blue Zircon Ring Collection
Turquoise ranks 5-6 on the Mohs hardness scale, making it suitable for rings worn with moderate care. The stone's blue-green color comes from copper content, while iron produces greener variations. Matrix patterns—the dark veining across the surface—form from the host rock where turquoise develops. Persian turquoise from Iran shows robin's egg blue without matrix. American turquoise from Arizona and Nevada often displays brown or black webbing. Tanzanite measures 6-7 on the Mohs scale and shifts between blue and violet depending on lighting and viewing angle. This trichroic property means a single stone can appear different colors from different directions. Heat treatment, standard in the industry, converts the natural brown-burgundy rough into the blue-violet finished gem. Blue zircon reaches 7.5 on the Mohs scale with high refractive index that creates noticeable sparkle. Natural zircon from Cambodia and Sri Lanka provides the material for most blue specimens. All rings ship free within the United States and feature real natural stones set in genuine .925 sterling silver.What are the three birthstones for December?
December has three recognized birthstones: turquoise, tanzanite, and blue zircon. Turquoise is the traditional stone with use dating back thousands of years. Tanzanite was added in 2002 by the American Gem Trade Association. Blue zircon serves as an alternative December stone.
Is blue zircon the same as cubic zirconia?
No. Blue zircon is a natural mineral (zirconium silicate) mined from the earth. Cubic zirconia is a synthetic material made in laboratories. Natural zircon formed billions of years ago and contains trace elements that create its color and brilliance.
How should I care for a turquoise ring?
Remove turquoise rings before washing hands, swimming, or applying lotions. Turquoise is porous and can absorb chemicals that alter its color. Store separate from harder gems that could scratch the surface. Clean with a soft dry cloth only.
