Costeira Diamond Strata, this eagerly anticipated collection, stands proud in form and precision. Distinctive and striking alone or layered together as in the Strata pictured here - creating an intriguing interlocking formation. This piece comprises a mesh of perfectly shaped kite frames, each enclosing a pair of meticulously micro-set stones. Modern and daringly different, Costeira — the Portuguese word for coastal — breathes adventure into every day, as if catching the light of the sun whilst dancing in the tenacious Atlantic winds.

The individual ring is available fully or half set - please enquire for half set prices. When layered together, the collection is metamorphosed into a look so wonderful and full of power.

SPECIFICATION:

Fully Set. Four separate rings, each perfectly crafted in precious metal holding bright white diamonds. Pictured with two in platinum with one each in 18ct yellow and 18ct rose gold. The stacking image only shows this combination although other variations are available. To view and purchase the rings separately click here.

COLLECTION OPTIONS:

The sensational Costeira is available in a host of precious stones set in platinum or 18ct rose, or yellow gold. It can be a full or half-set band or as a plain band. Other collection pieces will be developed throughout the year.

FAQ

Who is Andrew Geoghegan? +
An award-winning jewellery designer, my journey began in a humble garden shed – today I create inspired, unique and beautiful pieces for clients across the world, each one a testament to technical mastery. I split my time between the UK and Portugal, drawing inspiration from nature, life experience, and ancient artefacts. Read more in the About page.
Where are the pieces made and are the materials ethically sourced? +
The majority of AG pieces are made in the UK, and we also work with a trusted Portuguese workshop. All of our suppliers are members of recognised industry bodies that promote ethical trading. We use trusted UK and international partners to source the finest materials, and all our diamonds come from suppliers who comply with the Kimberley Process.
How can I view your pieces in person? +
If you’d like to view a piece before ordering, please get in touch. We’ll advise you on the best way to see it in person – whether via private consultation or another option that suits you.

Can I customise one of your designs? +
Absolutely – collection pieces can be tailored to your preferences, from stone type and size to metal choice. For something entirely personal, explore our bespoke service.
What about engraving? +
We offer both hand and laser engraving on most designs, available for an additional fee.
How does your bespoke service work? +
We’ll guide you through every stage – from your first idea to the finished piece. It begins with a conversation and unfolds through sketches, stone sourcing, and ultimately the creation of your one-of-a-kind design.
Do you ship internationally? +
Yes – we ship worldwide. Please note that if you're outside the UK, duties, taxes, and VAT may apply and will be your responsibility. If you’d like an estimate or advice, we’re happy to help.

What is your warranty and returns policy? +
We take great pride in our craftsmanship. If a manufacturing fault arises within 12 months, we’ll repair the piece free of charge.

Unworn cufflinks may be returned within 90 days in their original condition and packaging. Return shipping is the customer’s responsibility.
