This birthstone necklace for December is the gift she'll reach for every single day. A vivid turquoise-blue infinity pendant suspended on a delicate 925 sterling silver chain — a simulated turquoise stone, not a mined one, that captures the rich, sky-deep color of December's birthstone and makes it wearable for birthdays, holidays, and everyday layering. Whether you're shopping for a December birthday or simply love the calming blue hue, this pendant delivers fine-jewelry aesthetics at an honest price.

What Makes This Birthstone Necklace Different

Most birthstone necklaces at this price point use brass or zinc alloy bases that turn green within weeks. This pendant is built on a genuine 925 sterling silver chain — the same base metal used in pieces costing five times as much. The pendant itself is finished with rhodium plating to protect the silver and keep it bright. The turquoise-blue stone is a precision-cut simulated gem that mirrors the vivid color of natural turquoise without the fragility or high cost.

What really sets this apart is the infinity symbol design. The figure-eight silhouette carries meaning — endless love, eternal connection — making it a thoughtful gift that goes beyond the birthstone alone. The pendant sits at the perfect length to layer with longer chains or wear solo against a collarbone.

Compared to brass-plated alternatives sold elsewhere for similar prices, the 925 sterling silver base means no green skin, no surprise tarnish on the neck, and a piece that genuinely holds up to daily wear over months, not weeks.

How to Style This December Birthstone Necklace

The turquoise-blue infinity pendant pairs beautifully with cool-tone outfits — navy, white, and grey all make the stone pop. Wear it solo on a night out or layer it with a dainty gold chain for a mixed-metal look that's very on-trend. The 18-inch chain length sits just below the collarbone, making it universally flattering.

For gifting, this necklace arrives ready to present. It's the kind of thoughtful, personalized gift that resonates — December birthdays often get overlooked in the holiday rush, and a birthstone piece acknowledges the person, not just the season. Pair it with a handwritten note about the meaning of the infinity symbol for a memorable gift moment.

It layers well with our sterling silver chains and dainty initial necklaces. The infinity pendant's moderate size — substantial enough to see, small enough to not overwhelm — makes it one of the most versatile pieces in the birthstone range.

Care & Longevity

925 sterling silver with rhodium plating is one of the most durable finishes available at this price point. To keep it looking its best, remove before swimming, showering, or applying perfume and lotions. Store in the included pouch when not wearing. The rhodium layer protects against tarnish, but occasional gentle polishing with a soft cloth will keep it bright.

With proper care, this necklace will remain beautiful for years. Unlike gold-plated pieces where the plating can wear through on high-friction points, sterling silver with rhodium is exceptionally stable for pendants and chains that don't experience constant abrasion.

Frequently Asked Questions

Is this birthstone necklace for December hypoallergenic?

Yes. The chain and pendant are made from 925 sterling silver with rhodium plating — completely nickel-free and safe for sensitive skin.

Is this solid silver or plated?

The chain is 925 sterling silver (92.5% pure silver) with a rhodium protective coating. The pendant is also sterling silver based. This is a genuine sterling silver piece — not brass or zinc alloy.

Will it tarnish?

With proper care, no. The rhodium plating significantly slows tarnishing. Keep it dry, away from perfume and chlorine, and store in a dry pouch when not wearing.

Can I wear this in the shower?

We recommend removing it before showering, swimming, or exercising. Occasional splashes are fine — just dry it immediately.

What is the chain length?

The chain is approximately 18 inches with a small extension for adjustability. This length sits at or just below the collarbone, making it ideal for wearing solo or layering.

Is this a good gift for a December birthday?

Absolutely. The infinity design adds a layer of meaning beyond the birthstone — it's a thoughtful, personalized gift that arrives ready to present. December birthdays near the holidays often appreciate a gift that's clearly chosen for them, not picked up last-minute.

What is December's birthstone color?

December has three recognized birthstones — turquoise, tanzanite, and blue zircon — all sharing that signature cool blue-green hue. This pendant captures the classic turquoise-blue shade associated with December.

✨ Care Instructions

💧 Water Remove before swimming, showering, or washing hands. Water is the #1 cause of premature tarnish on gold-plated jewelry.
🌸 Chemicals Put jewelry on after applying perfume, lotion, and hairspray — not before. Chemicals break down the plating layer over time.
🧽 Cleaning Wipe gently with a soft dry cloth after each wear to remove skin oils. Never use silver polish, ultrasonic cleaners, or abrasive cloths.
📦 Storage Store in the included gift box or a soft pouch, away from direct sunlight and humidity. Keep pieces separate to avoid scratches.
⏰ Daily wear Remove before sleep, gym, and housework. With proper care, 18K gold plating over 925 sterling silver lasts 2–4 years of daily wear.

Yes. The chain and pendant are 925 sterling silver with a rhodium finish -- nickel-free and suited to sensitive skin.

Neither -- it's 925 sterling silver, finished in rhodium rather than gold. There's no gold layer on this piece; the bright silver-white tone in every photo is the rhodium finish over the sterling base.

No. The pave stones along the infinity band and the clear center stone are lab-created cubic zirconia. Worth knowing before you buy: the stone reads as a vivid, fully saturated blue in every one of this piece's own photos, closer to December's other birthstones (blue zircon or tanzanite) than to turquoise's characteristic blue-green. We'd rather say that plainly than let the product name imply a color match the photos don't back up.

December has three recognized birthstones -- turquoise, tanzanite, and blue zircon -- all in the same cool blue family. This piece's cubic zirconia is cut and colored to represent that family of blues rather than one specific mined gem.

Rhodium plating slows tarnishing noticeably. It isn't permanent, so a soft polishing cloth will restore the shine if it dulls over time -- keep it dry and away from perfume, lotion, and chlorine to make it last.

We'd remove it first. Water, chlorine, and steam are the fastest ways to wear down a rhodium finish -- a quick splash is fine if you dry it right after.

A 16.5-inch box chain with a 2-inch extender, so it adjusts from 16.5 to 18.5 inches, closing with a spring-ring clasp.

Yes -- the blue pave marks the month, and the infinity shape adds a “forever” meaning that works well for birthday or holiday gifting. It arrives in a gift-ready box, and US shipping is free on every order.
