The Maxi Silver Astrid Necklace, a standout from our 1763 Collection, captures the essence of ocean treasures. Created from recycled sterling silver, it features a stunning 12x10mm sky blue topaz gemstone, evoking the beauty of the sea. Chain length of 50cm and the pendant measures approximately 2cm in length and 1. 5cm in width. Presented in a sleek ocean blue matchbox-style box with our logo embossed in gold foil, the necklace comes with a complimentary polishing cloth to keep it sparkling. To ensure its longevity, we recommend removing the jewellery when bathing or showering, especially when near salt or chlorine-rich water, as these substances can cause discoloration and damage to the metal. Additionally, it is important to keep your Dainty London jewellery away from extreme heat as the stones may crack. Over time, all silver jewellery can become tarnished and lose its shine due to contact with air and the moisture, acid, and oils found on the skin. To minimise this effect, it is best to store your jewellery in a cool, dry, and dark place in an airtight container. We include a jewellery cleaning cloth with each order to help reduce tarnishing. Occasionally, you may need to clean your jewellery. This can be done with a soft baby's toothbrush and liquid soap. Rub gently in a circular motion until you see the shine return.
