Precious Metals at Sophia Jewelers
Our jewelry comes in a range of metals, from gold, platinum and sterling silver to stainless steel and titanium. Each product page lists its exact metal.
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. Lab-grown diamonds are conflict-free by origin. Grading reports are included only when the individual product details specify one.
Necklace Length Guide
Chain length determines where a necklace sits on the body. Here is a quick reference:
- 14 inches (Choker): Sits at the base of the throat. Works with open necklines and off-shoulder styles.
- 16 inches (Princess): Rests at the collarbone. The most popular length for pendants and solitaire necklaces.
- 18 inches: Falls just below the collarbone. The most versatile all-purpose length — flatters most necklines and pendant sizes.
- 20 inches (Matinee): Sits at the top of the chest. Works well with higher necklines and larger pendants.
- 22-24 inches: Falls across the chest. Great for layering and statement looks.
- 28-30 inches (Opera): Dramatic length, sits below the neckline. Can be worn doubled for a different look.
When in doubt, 18 inches is the safe choice — it suits most necklines and pendant sizes.
Necklace Types at Sophia Jewelers
- Chain necklace — a continuous metal chain, the foundation of any jewelry wardrobe
- Pendant necklace — a chain with a single decorative element hanging from a bail
- Tennis necklace — a continuous line of diamonds or gemstones in a flexible setting
- Station necklace — a chain with evenly spaced stones or charms — elegant and understated
- Lariat / Y-necklace — a long chain that loops through itself, creating a Y shape
- Choker — a close-fitting necklace that sits at the throat, typically 14-16 inches
Clasp Types
- Lobster claw — the most secure clasp, standard for most fine necklaces
- Spring ring — lighter and slimmer, common on delicate chains
- Toggle — T-bar through a loop, decorative and easy to use one-handed
- Box clasp — clicks shut, used on heavier and multi-strand necklaces
The clasp type for each necklace is noted in the product description.
Layering Necklaces
Vary chain lengths by 2-4 inches between each layer. Mix chain widths and styles for texture. Combine a plain chain with a pendant necklace and a station necklace for a complete layered look. Two or three layers is the sweet spot — more than four tends to look busy.
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.

What affects the price of By the Sea jewelry?
Metal, size and added stones set the price. 14K or 10K gold costs more than sterling silver, and larger or heavier pieces use more metal. Diamond, lab-grown diamond or cubic zirconia accents also change it. Use the Price filter on this page to set a budget.
Which By the Sea styles are most popular?
Dolphins, shell pendants and sand dollars lead the list. Wave and dolphin bracelets, dolphin hoop earrings, and scallop and clam shell pendants follow closely. Turtles, starfish studs and whale tail rings also appear near the top.
Should I choose a sea charm or a sea pendant?
Choose a charm for a bracelet, a pendant for a chain. A charm attaches to a charm bracelet or holder and needs no chain. A pendant hangs from a chain you add, so pick one if you want a necklace look.
Is sterling silver or 14K gold better for beach-themed jewelry?
Both work; it depends on budget and look. Sterling silver is a bright, affordable choice for charms and pendants. 14K gold has a warmer richness and suits pieces you plan to wear daily. Rinse and dry either after swimming. See our jewelry care tips.
What are lab-grown diamond whale tail pieces?
They are whale tail designs set with lab-grown diamonds. Lab-grown diamonds are real diamonds created in a lab rather than mined. Here the whale tail comes as a ring, necklace and bangle in sterling silver, with different total carat weights.
What ocean gift suits a beach lover?
A turtle, dolphin or shell pendant is an easy gift. Small starfish or scallop shell studs suit someone who prefers simple earrings. Textured or enameled finishes add shine or color, and a charm works well for someone who collects bracelet charms.
