The September Birthstone Necklace is a 925 sterling silver infinity pendant, rhodium plated, set with blue cubic zirconia pave and a clear round CZ at its center. Sapphire is September's birthstone; this piece captures that blue in a lab-created stone rather than a mined one, and says so plainly. One of twelve birthstone necklaces built on the same infinity design and the same sterling chain -- pick a different month from the picker above and the page carries the same honesty with it.

What Makes This Different

  • 925 Sterling Silver, Rhodium Plated — Not brass, not zinc alloy. A sterling silver base finished in rhodium for shine and tarnish resistance, not gold.
  • Cubic Zirconia, Not a Mined Sapphire — The blue pave stones and the clear center stone are lab-created cubic zirconia. A natural sapphire at this size and clarity would cost far more than $59.99.
  • Nickel-Free — Sterling silver's standard alloy doesn't include nickel, the metal most people react to in costume jewelry.
  • Layering-Friendly Profile — A fine box chain and a slim infinity pendant, sized to layer without tangling or competing with other pieces.

How to Style the September Birthstone Necklace

This necklace is the kind of piece you reach for first. It works with a deep V-neck tee, a button-down left partially open, or a strapless dress. The pendant sits at the ideal focal point -- below the collarbone, above the chest -- drawing the eye without overwhelming.

For layering, pair this with a longer 20-22 inch chain necklace for a two-layer look, or add a shorter choker above for a three-piece stack. Silver tones pair naturally with each other, so mixing AJLuxe pieces creates cohesion rather than clash.

Gift-wise, this ships in gift-ready packaging. It's a strong choice for birthdays, Mother's Day, graduations, or any moment tied to a September birthday.

Care & Longevity

Rhodium plating resists tarnish well but is not indestructible -- what wears it is chemistry and friction: perfume, hairspray, chlorine, sweat, and being tumbled in a drawer with other chains. Build these habits and the piece will look sharp for years:

  1. Last on, first off — put jewelry on after applying products; take it off before washing hands, showering, or swimming.
  2. Wipe after wearing — a quick pass with a soft dry cloth removes skin oils and residue that build up through the day.
  3. Store in the pouch — the included pouch prevents scratching and reduces air and humidity exposure between wears.

The 925 sterling silver base underneath the rhodium finish will not rust or degrade.

Frequently Asked Questions

What is this necklace made of?

The chain and pendant base are 925 sterling silver with a rhodium finish. The stones are cubic zirconia (CZ) -- blue pave lining the infinity shape, with one clear round stone at the center.

Is the blue stone a real sapphire?

No -- it's cubic zirconia, colored to read as September's sapphire blue. A genuine mined sapphire at this size and clarity would cost significantly more than this piece.

What length chain does this necklace come with?

A 16.5 inch box chain with a 2 inch extender, so it wears anywhere from 16.5 to 18.5 inches.

Can this necklace be layered?

Yes -- it's designed with layering in mind. Pair it with a longer pendant for depth, or a choker for a tiered look. The slim profile doesn't compete with other pieces.

Is this necklace hypoallergenic?

Yes. The base is 925 sterling silver -- nickel-free and suited to sensitive skin.

Can I wear this necklace every day?

Yes, but take it off before showering, exercising, or applying skincare -- that habit extends the life of the rhodium finish and keeps the pave stones secure.

How do I clean this necklace?

Wipe with a soft, lint-free cloth after wearing. For deeper cleaning use a slightly damp cloth only -- no jewelry cleaning solutions, ultrasonic cleaners, or soaking. Dry immediately.

✨ 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.

No, and we say so plainly: the blue pave and center stone are lab-created cubic zirconia, colored to capture sapphire's deep blue. A natural mined sapphire at this size and clarity would cost significantly more than $59.99 -- we'd rather disclose a simulant than imply otherwise.

Yes. The chain and setting are 925 sterling silver -- 92.5% pure silver -- finished with a rhodium plating. It is not silver-plated brass or a base alloy underneath.

Rhodium is a hard, bright white-metal finish plated over the sterling silver -- it's what keeps the piece bright and tarnish-resistant day to day. Like any plating it's a surface layer, so avoid chemicals, perfume and hard knocks against it and it will hold up well; a soft cloth restores the shine if it ever looks dull.

Yes. 925 sterling silver with rhodium plating is nickel-free, which is why it's a common choice for sensitive skin.

16.5 inches with a 2 inch extender, so it sits at the collarbone and adjusts to about 16.5-18.5 inches depending on where you fasten it.

We recommend taking it off first. Chlorine, salt water and prolonged moisture aren't kind to any plated finish, rhodium included -- keep it dry and it lasts a lot longer.

This same infinity pendant is made in all twelve birthstone colors, each on its own product page -- pick your month from the birthstone picker above to see the matching stone.
