Harkness jewellery is crafted from high-quality metals and precious stones and is meant to be enjoyed, worn every day and treasured as future heirlooms.We use a lot of precious stones in our designs and the settings are designed to hold each stone in place securely. If the product becomes disfigured (through knocks or abrasive contact) it can alter the setting. This opens up the risk of stones falling out. We have chosen to use 9K gold in our designs a the combination of pure 24k gold and other alloys makes it a highly durable gold and the most resistant to wear and tear. Please note, no matter the karat or type of precious metal, signs of wear will appear as you go about your daily life, inevitably collecting markings along the way. To keep your pieces in the best possible condition and ensure a long life, we recommend:Treat with care and avoid activities that expose your jewellery to knocks and scratches (such as sports, gym, lifting heavy objects and gardening).Remove your jewellery before bed, showering, swimming and washing your hands.Avoid exposing your jewellery to perfume, chemicals and cosmetics.Cleaning: To preserve the brightness of your pieces, it is important to clean them often. We advise you to use a very soft toothbrush and a small amount of neutral-pH liquid soap and gently brush over stones. Rinse with fresh warm water and dry with a soft cloth. Rhodium plated designs: For these designs we advise you to submerge the product in neutral-pH liquid soapy water and then rinse with fresh warm water and dry with a soft cloth. Do not brush directly onto the rhodium plating.Storage: Jewellery should be stored separately so your items do not rub against each other and cause scratches. We advise that you store each piece in its original box, or alternatively wrap each piece in a soft cloth and store in a dry, cool place to prevent it from being tarnished, scratched or tangled. We want these pieces to be the last you’ll ever buy, so double-check the security of your gems (which can shift or become loose after prolonged exposure to the elements) and clasps before wearing.All our pieces are produced by hand, our coloured stones will vary slightly and no two pieces are identical.
