These necklaces use both simulated/lab-made stones and natural shell-based stones. Examples include cubic zirconia (including red/ruby-color CZ used as a July birthstone) and Mother of Pearl; some listings explicitly label stones as “simulated.”
Chains and settings use a mix of metals and platings, including sterling silver (925), brass, 18K yellow gold, 14K yellow gold, 14K gold over brass / 14K gold plated over brass, and rhodium over brass.
Some listings note hypoallergenic or low-allergen designs. Specific claims include nickel-free, lead-free, cadmium-free, and formulations described as hypoallergenic or suitable for sensitive skin.
Listed pendant sizes include a 24 mm (1") birthstone pendant; a small cross at 23 mm × 15 mm (0.91" × 0.59"); and a clover pendant around 0.72" × 0.81".
Reported closures include spring-ring clasps, lobster-claw clasps, slide closures, and some entries listed simply as a generic “clasp.”
Styles shown include birthstone pendant necklaces, clover or Mother of Pearl pendants, Y-shaped lariat necklaces, cross pendants, and small puffed-heart or other dainty pendant silhouettes with stone accents.
