Petite Theory Jewellery Co.

A younger line under The Crystaling Company. We create unique sterling silver and gold vermeil pieces designed to empower our clients, while remaining versatile and comfortable enough for everyday wear. Featuring Natural Gemstones in vibrant, candy-like colours, each piece is sweet, playful, and made to shine. Currently available in Aberdeen Marina Club and our online store.

Hydrojewels

The Original waterproof jewellery line. Hydrojewels can withstand sweat, freshwater, and lotions without fading. Our jewellery is made from top-quality medical-grade steel, the type of luxury steel that Swiss watchmakers use.

Our Hydro Lab ensures our pieces are durable, corrosion-resistant, hypoallergenic.
