1 Carat Moissanite Key Pendant Necklace | 101300557233939

How to measure your necklace

1. Center stone size: 1 carat moissanite (diamond-equivalent) is approximately 6.5 mm face-up for a round cut. For other shapes, use the longest edge as the reference.
2. Pendant height: Measure from the top of the bail to the tip of the key. Typical key pendants are about 25–35 mm tall and 8–12 mm wide at the bow.
3. Chain length: Wrap a string where you want the pendant to sit, measure it, then select the closest standard length (16, 18, 20, 22, or 24 in). Add 1–2 in for a looser drape or layering.
4. Drop estimate: Chain length − half your neck circumference + pendant height ≈ where the tip of the key will fall.

Quick conversion: 1 inch = 25.4 mm.

Materials & details

• Moissanite gemstone: Lab-grown silicon carbide with exceptional brilliance and fire (refractive index ~2.65–2.69), excellent durability (Mohs ~9.25), and long-term clarity that does not cloud.
• Stone grading: High-quality moissanite commonly ranges D–F in color and VVS–VS in clarity; exact grading can vary by batch and size.
• Metal & finish: This style is commonly crafted in 925 sterling silver (often rhodium plated to reduce tarnish), gold vermeil over sterling silver, or solid gold. Please refer to the options on this page for the exact metal and finish.
• Sensitivity note: If nickel-sensitive, opt for rhodium-plated sterling or solid gold where available and confirm the option details before purchase.

About carat and size: Many moissanites are sold by diamond-equivalent weight (DEW). A “1 carat” round typically measures about 6.5 mm face-up.

Model & fit reference

• Common chain lengths on most necks:
  • 16 in: Sits at the base of the neck.
  • 18 in: Rests at or just below the collarbone (most popular for pendants).
  • 20 in: Slightly below the collarbone; good with higher necklines.
  • 22–24 in: Mid-bust on most wearers.
• Scale cues: A 6.5 mm stone is roughly the width of a pencil eraser; a 30 mm key is about the height of a typical house key.
• Layering tip: Leave 2–4 inches between chains (e.g., 16 in with 18–20 in) to prevent tangling and showcase the pendant.

Care guide — keep it lovely longer

• Last on, first off: Avoid contact with lotions, perfume, hairspray, sunscreen, chlorine, and household cleaners.
• Routine cleaning: Soak in warm water with a drop of mild dish soap, brush gently with a soft toothbrush, rinse, and pat dry with a lint-free cloth.
• Ultrasonic use: Generally safe for moissanite in solid gold settings; avoid ultrasonic and steam cleaners for plated or vermeil pieces.
• Storage: Keep separate in a soft pouch or box to prevent scratches; store sterling silver in an anti-tarnish pouch.
• Maintenance: Remove before swimming, workouts, and heavy impact. Check prongs and the bail periodically and tighten if needed.
• Silver care: Use a non-abrasive silver polishing cloth; avoid abrasive pastes on plated finishes.

Style tips

• Everyday shine: Wear solo on an 18 in chain to highlight the key and 1 ct sparkle.
• Layered look: Pair with a delicate choker (14–16 in) and a longer chain (20–22 in) for dimension.
• Necklines: V-necks and open collars frame 16–18 in best; crew and boat necks pair well with 20 in.
• Mixing metals: Moissanite’s neutral sparkle complements silver and gold—stack confidently with your daily chains.
• Meaningful gifting: The key motif symbolizes new beginnings and “the key to my heart,” perfect for graduations, anniversaries, and milestones.
