Why Buy December Birthstones from GemSelect?

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.

Zircon brings lively brilliance and can be an attractive choice for shoppers who want a sparkling December birthstone with strong visual presence.

Loose December birthstones including turquoise, tanzanite and zircon

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.

December Birthstone FAQs

What are the birthstones for December?

The best-known modern December birthstones include turquoise, tanzanite and zircon. Each offers a different look, from opaque blue-green turquoise to violet-blue tanzanite and brilliant blue zircon.

Is zircon the same as cubic zirconia?

No. Zircon is a natural gemstone, while cubic zirconia is a man-made diamond simulant. They have different composition, appearance and gemstone value.

Check the gem’s size, shape, color, cut style, clarity description and any treatment or origin details listed on the product page. These details help you choose a stone that fits your jewelry project.

The citrine gems are beautiful. I appreciated that each stone was individually shown on the website so I could see exactly what I was getting. No mystery person selecting random stones for me. The documentation included with each gem was high quality as well. Great price and arrived as expected.
