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. 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.

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.

Which December birthstone is best for custom jewelry?

The best choice depends on the design and how the jewelry will be worn. Turquoise is popular for bold cabochon styles, tanzanite for elegant blue-violet designs and zircon for bright, sparkling pieces.

What should I check before buying a loose December birthstone?

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.

I could see the actual gem I was buying

This is the first time I have used this site. I was dissatisfied with the quality of gems and supplies elsewhere and decided to try GemSelect. They are awesome! I was thrilled to see the variety and the great web performance. There was the ability to search for information as well as gems. Things like the clarity rating system and caret weight of the gems. I have always loved making things and I have just started to make jewelry as a business. However I have never made a ring before and have always wanted to. On GemSelect I was able to find good quality gems to use in my creations. I am so glad the website is so easy to use. Thank you GemSelect.

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.

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc
