Infinity Slide Pendant in Sterling Silver with Lab-Created Ruby & Cubic Zirconia

Pairs Well With
More pieces in the same metal and style.
Product Overview
An infinity motif gives this slide pendant a flowing, modern shape, finished in a bright polished surface. A round red ruby sits at its heart, with a small Cubic Zirconia beside it adding a flash of clear sparkle.
Sterling silver with a rhodium finish gives the pendant its cool, bright shine, while the open back keeps it light. The red stone and silver-tone surface create a clean contrast that looks equally at ease with denim or an evening outfit.

Precious Metals at Sophia Jewelers
Every piece is crafted from certified precious metals selected for lasting brilliance and skin-safe wear.
14k Gold (Most Popular)
58.3% pure gold. The ideal balance of durability and color richness. Available in yellow gold, white gold, and rose gold. The standard choice for fine jewelry.
18k Gold (Premium)
75% pure gold. Richer in color, slightly softer than 14k. Preferred for heirloom and statement pieces where purity matters most.
10k Gold (Everyday Value)
41.7% pure gold. The most durable gold alloy — ideal for active wearers. Stamped 417 on the piece.
Sterling Silver
92.5% pure silver, stamped 925. Cool-toned and versatile. Best for occasional wear; silver develops a natural patina over time.
Platinum
Naturally white, hypoallergenic, and the most durable precious metal. Recommended for those with nickel sensitivities.
Titanium & Stainless Steel
Lightweight, hypoallergenic, and virtually maintenance-free. Excellent for everyday wear and sensitive skin.
Lab-Grown Diamonds
Lab-grown diamonds are physically, chemically, and optically identical to mined diamonds. Same carbon crystal structure, same hardness (10 on the Mohs scale), same brilliance. Created in a controlled environment, lab-grown diamonds are typically 50-70% less expensive than comparable mined stones. All Sophia Jewelers lab-grown diamonds are conflict-free by definition and independently graded by IGI or GIA.
Choosing the Right Pendant or Charm
Pendant Sizing and Chain Length
The chain length determines where a pendant sits on the body. A quick reference guide:
- 14 inches (Choker): Sits at the base of the throat. Works with small, delicate pendants only.
- 16 inches (Princess): Rests at the collarbone. The most popular length for solitaire and small pendants.
- 18 inches: Hangs just below the collarbone. Versatile — suits most pendant sizes and necklines.
- 20-22 inches (Matinee): Sits on the chest. Works well for larger, statement pendants.
- 24-30 inches (Opera): Falls below the neckline. Best for bold pendants or layered looks.
As a rule: larger and heavier pendants look best on longer chains. Small, delicate pendants can feel lost on a long chain.
Layering Pendants
Vary chain lengths by 2-4 inches between each layer. Classic three-layer: 16", 18", 20-22". Mix pendant sizes from small at the shortest layer to larger at the longest. Mixing chain styles — box chain, cable chain, snake chain — adds texture without clutter.
Charm Bracelet Compatibility
Charms are designed to attach via lobster claw clasp or jump ring to a bracelet or chain. Standard compatibility works with bracelets that accept 3-5mm wire gauges. Contact us with your bracelet details and we will confirm compatibility before you purchase.

- Cluster pendant — multiple stones arranged together for maximum brilliance
- Locket — opens to hold a photo or keepsake; a timeless heirloom style
- Cross pendant — available in plain metal and gemstone-set styles across all metals

Caring for Your Jewelry
Fine jewelry deserves thoughtful care. These guidelines will keep your pieces luminous for years.
Daily Wear
- Remove jewelry before swimming, showering, or using cleaning products
- Apply lotion, perfume, and hairspray before putting on your jewelry
- Avoid wearing jewelry during gym workouts or high-contact activities
- Put jewelry on last when getting dressed
Cleaning at Home
Mix a few drops of mild dish soap with warm water. Soak for 15-20 minutes, then gently scrub with a soft toothbrush. Rinse thoroughly and dry with a lint-free cloth. Safe for gold, platinum, and most gemstones. Avoid ultrasonic cleaners for pearls, opals, and emeralds.
Storage
Store each piece separately in a soft pouch or compartmentalized jewelry box to prevent scratching. Keep chains laid flat or hung to avoid tangling. Store silver in anti-tarnish pouches to slow oxidation.
Professional Care
Have precious stone jewelry professionally cleaned and inspected once a year to check prong integrity, stone security, and clasp function.

Are the rubies in these pendants natural or lab-created?
Most titles here say lab-created ruby. Lab-created rubies have the same crystal structure and red color as natural ones. As a general rule, many natural rubies are heat treated to improve color, so check each product title and description for the stone type.
Is a ruby pendant durable enough for everyday wear?
Yes, ruby is a hard gemstone that suits daily wear. It rates 9 on the Mohs scale, just below diamond, so it resists scratching. Sterling silver pendants are a light everyday choice, and a bezel or halo setting helps protect the stone. See our jewelry care tips.
What is the difference between a slide and a regular pendant?
A slide threads onto a chain, while a pendant hangs from a bail. Chain slides here, like the heart and cushion styles, sit flat against the chain and can move along it. Both styles show the ruby well, so choose by the look you prefer.
Which ruby pendant works best as a July birthstone gift?
A heart pendant or heart locket is an easy gift choice. Several styles are labeled July birthstone, including lockets in sterling silver and 14K yellow gold. Choose sterling silver for a casual everyday piece, or gold when you want the gift to feel more special.
