small crescent moon pendant

Sizes vary from very tiny half-moon charms (around 6 mm × 8 mm) up to larger pendants (about 37 mm × 32 mm, ~3.5 cm). Several common small sizes fall in the 14–28 mm range.

Some pendants are sold without a chain while others include one. Included chain lengths in listings range from about 16 inches (including 16–18 inch adjustable chains) up to 24 inches; several specifically list an 18-inch chain with a 2-inch extender.

Listings show a variety of clasps: continuous/closed loops, generic unnamed clasps, spring-ring clasps, and lobster-claw clasps. Specific clasps vary by listing, so check the product details if you need a particular style.

Common options include mother-of-pearl inlay, rhinestone accents, cubic zirconia, amethyst/crystal choices, and glow-in-the-dark stones described as moonstone-like in several colors.

Some necklaces feature glow-in-the-dark stones in colors listed as Sky Blue, Green, Purple and Blue.

Several listings include suggested ages (for example, 8–17 years or 9 years and up). One listing notes third-party lab testing and compliance with CPSIA and ASTM F2923 standards for children’s jewelry.

Some listings include gift packaging, mentioning a custom or branded gift box or explicitly stating that a gift box is included. Packaging varies by seller, so check the product details if gift-ready packaging is required.
