Diamond necklaces are the most underbought category in fine jewelry. They photograph well, pair with anything, and in lab-grown they deliver more sparkle per dollar than any other product category.
Key takeaway
Four styles dominate: solitaire pendant, station necklace, bezel set pendant, and riviere. Sweet spot for solitaire: 0.5–1 carat. Chain: solid 14K or 18K gold, cable or box link. Chain length: 16, 18, or 20 inches (18 is most versatile).
The four necklace styles
1. Solitaire pendant
A single diamond on a chain. The necklace equivalent of the solitaire engagement ring. Works with every neckline.
2. Station necklace
Multiple diamonds spaced evenly along a chain, each in a small bezel. Layers beautifully.
3. Bezel set pendant
A diamond wrapped in metal, suspended from a chain. Modern alternative to prong-set solitaire. Snag-resistant, secure.
4. Riviere (diamond eternity necklace)
Diamonds set continuously along the entire chain. Statement piece.

Chain types
- Cable: Oval links. Strong, classic. 1.0–1.7mm gauge.
- Box: Square links. Resistant to tangling.
- Rope: Twisted. Decorative.
- Wheat: Angled overlapping links.
Avoid hollow chains for valuable pendants
Key Insight: Hollow chains are cheaper but cannot be repaired if broken. For any pendant over $500, insist on solid.
Clasp choices
- Spring ring: Most common but can fail under load.
- Lobster clasp: More secure. Recommended for valuable pieces.
- Barrel/screw: Very secure. Best paired with safety chain.
Common mistakes
1. Matching chain gauge to length, not weight
An 18-inch 0.8mm chain with a 1.5ct pendant droops. Match chain weight to pendant first.
2. Skimping on clasp quality
A $1,500 pendant with a $3 clasp will eventually be lost.
3. Ignoring pendant drop
The bail adds 2–5mm to drop. An 18-inch chain with a 4mm bail sits at 18.5 inches effective.
4. Gold plating on higher-value pieces
Gold-plated chains wear through within 1–3 years. Solid gold only for long-term.

Shop NecklacesFAQs

18 inches. Sits above the bust, works with every neckline.
Can diamond necklaces be worn daily?
Expert Tip: Yes. Take off for sleeping, showering, exercise. Annual clasp inspection recommended.
How do I know if a chain is solid gold?

Diamonds set continuously along the entire length. 16–20 inches, 3–10ct TCW for statement range.
