Green Onyx: Green Onyx is a smooth, opaque to translucent green stone and a member of the Chalcedony family. The green color is typically achieved through dyeing natural Agate or Chalcedony, which is a standard and accepted industry practice. Sourced primarily from India, Brazil, and Pakistan.

Tourmaline: Tourmaline is a group of boron silicate minerals occurring in the widest range of colors of any gemstone, including pink, green, blue, yellow, black, and watermelon. Color is caused by varying trace elements and is natural, though some varieties are heat-treated to improve saturation. Major sources include Brazil, Afghanistan, Nigeria, and Mozambique.

Gold Plate Recycled Brass

Our jewellery is demi-fine and deserves a little care. 

Jewellery goes on last, comes off first — after perfume, moisturiser, and hairspray, and before you shower, swim, or work out.

Avoid prolonged exposure to moisture, chlorine, and harsh chemicals. These will wear down gold plating over time.

Store pieces individually in the pouch provided. For sterling silver, an airtight bag reduces tarnishing.

Clean gently with a soft cloth after each wear. For a deeper clean, use a silver polishing cloth. Never use alcohol-based or abrasive cleaners on plated pieces or gemstones.

Every gemstone used in our pieces is natural and one of a kind. Variations in colour, tone and inclusions are part of their inherent character, not flaws.
