December Birthstones: Turquoise, Tanzanite and Zircon

Shop Loose December Birthstones

December is represented by a beautiful range of blue gemstone choices, from the classic blue-green character of turquoise to the violet-blue elegance of tanzanite and the bright sparkle of zircon. This category brings together loose natural gemstones suited for personalized birthstone jewelry, collector pieces and custom designs.

Turquoise, Tanzanite and Zircon Styles

Turquoise offers an opaque, earthy look that works well in statement rings, pendants, beads and artisan-inspired jewelry. Tanzanite is prized for its rich blue to violet-blue appearance, making it a refined option for elegant earrings, pendants and center stones. Zircon brings lively brilliance and can be an attractive choice for shoppers who want a sparkling December birthstone with strong visual presence.

Choosing a December Birthstone

When comparing these gemstones, consider the jewelry style, preferred color, cut, size and setting type. Turquoise is ideal for bold color and a smooth cabochon look, while tanzanite and zircon are often selected in faceted cuts for light return and depth of color. Always review each gemstone listing for measurements, shape, weight, clarity, origin notes and any treatment information provided.

Loose Gems for Custom Jewelry

Buying a loose December birthstone gives you more flexibility than choosing finished jewelry. You can match the gem to a specific design, choose the best shape for your setting and create a meaningful gift for a December birthday, anniversary or personal milestone. For rings or daily-wear pieces, discuss setting protection and suitability with your jeweler before finalizing a design.
