CARING FOR YOUR JEWELLERY

We generally recommend using a soft jewellery polishing cloth once a week to wipe the surface of your jewellery. This will help to prevent tarnishing of the metal but also to remove any dust, perfume or other particles that daily wear can attract. Brands such as Town Talk Polish Co. offer excellent polishing cloths, specifically for jewellery and can help prevent the gradual dulling of your jewellery. We would discourage using commercial liquid
polish, as these can sometimes be too abrasive, and when used too liberally, can also remove any deliberate oxidisation detail. Most diamond and precious stone jewellery (with the exception of opals, pearls and emeralds) can be cleaned in warm water, using a mild detergent such as washing up liquid. You can also use a soft toothbrush to reach underneath any claws or backs of pieces. Always dry your jewellery after cleaning with a soft cloth. Porous gemstones such as pearls, opals and emeralds should be cleaned using an untreated, dry, soft cloth. We do not recommend the use of any jewellery polishing cloths which have been impregnated with polishing agents for pieces with these gemstones in.We would also recommend removing rings when washing your hands or moisturising. Additionally, it is always advisable to avoid wearing jewellery when doing manual labour (such as gardening
or home DIY), cleaning, doing exercise or playing sports. We suggest that your jewellery receives periodic professional maintenance. This would include checking all of the claws (in gemset pieces) and generally giving the niece a full service and clean. You should store all jewellery in an enclosed and separate space to prevent pieces scratching against each other. A jewellery pouch or inside a jewellery box will suffice.

A SPECIAL ORDER

All of our fine collection pieces and bespoke pieces are handmade in our
London workshop in small quantities, which means that sometimes not all pieces are held in stock. We can, however, create a special order for you and this normally takes between around 3-4 weeks to complete, depending on the complexity of the piece. The piece can be personalized through engraving; adding initials, or a secret message to a loved one. We can also change the colour of the gemstones we use, or even the metal.

BESPOKE

Each bespoke creation is an exceptional experience and journey for both client and designer. A full bespoke service is offered in-house and our creative director, Ana de Costa works closely with clients to understand their tastes, style and ultimately the piece they wish to be designed and crafted. By understanding these simple objectives, Ana is able to guide you through the design process and technicalities; these include the types and qualities of gemstones, preference of metal, time-frames and the budget. Once created, each piece is accompanied by a professional photograph of your piece, any relevant gemstone certificates and an insurance valuation from the house. If you would like to discuss your idea for a bespoke commission, or have any questions regarding the process, please contact Ana de Costa,

THE QUALITY AND PROVENANCE OF OUR GEMSTONES

We are committed to sourcing the world’s most beautiful and ethically sourced gemstones; only using those from established suppliers. Ana de

Costa adheres to the Kimberley Process, never buying or trading rough or cut loose diamonds from areas where it would encourage conflict or human suffering. Every Ana de Costa diamond bears the hallmark of quality, accountability and provenance. The majority of Ana de Costa diamonds are laser inscripted with a unique Gemological Institute of America (GIA) tracking number, that whilst invisible to the naked eye, allows for its origin to be traced- all the while protecting the perfection and beauty of the stone. Coloured gemstones are also sourced in a stringent ethical fashion. Important gemstones are often supplied with laboratory certificates to verify their provenance.

THE PURCHASE OF GEMSTONES FOR INVESTMENT

As part of the bespoke service we are also able to purchase loose gemstones for clients as investment pieces. This is predominantly done with diamonds, due to the value increases that have been seen over the last decade. However, we are also able to purchase other valuable gemstones for clients, such as rubies, emeralds and sapphires. We have also worked closely with international clients to arrange secure storage of these valuable gemstones in safety deposit boxes.

VALUATIONS

A full valuation is supplied with each bespoke piece created and also with fine collection pieces from Ana de Costa. This valuation is in accordance to information required by insurers. Valuations for non Ana de Costa pieces can be supplied, however, these are charged at a standard cost of 3% of the value of the piece.
