Who We Are
Jewellery with a Modern Twist
Sterling Diamond is ideally located in the heart of Mayfair, within the iconic Burlington Arcade. We specialise in exceptional quality, hand-made jewellery using only the finest materials — including certificated diamonds from the world's leading gemological laboratories.
Our Master Jeweller designs and creates bespoke pieces to an exceptional standard. Whether it's an engagement ring, a statement necklace, or a unique piece to mark a special occasion, every creation tells a story crafted with precision and passion.
We offer complimentary jewellery and watch valuations. Bring your pieces to us and we will provide same-day quotes for cash purchase, trade-in, or consignment. We pride ourselves on offering the most competitive prices in London.

Watch Specialists

Our watch division specialises in pre-owned luxury timepieces from the world's most prestigious manufacturers. Every watch undergoes rigorous authentication and quality inspection by our certified horologists.
We deal exclusively in Rolex, Patek Philippe, Audemars Piguet, Richard Mille, Omega, and other leading Swiss brands. Whether you're looking to buy, sell, or trade, our specialists provide expert guidance and competitive pricing.
We also offer specialised watch sourcing for clients seeking specific references. Our extensive network allows us to locate rare and discontinued models that others cannot.
