Every single antique dealer on our platform is individually approved by our internal team. We verify their professional trade history, ethical standards, and photographic quality to ensure a secure, high-standard buying environment. Upon joining, every dealer agrees to a strict 9-point code of conduct. While issues can occasionally arise, our dealers typically resolve them swiftly and directly with the buyer. In fact, since our founding in 2002, Sellingantiques has only had to step in to help resolve an issue on roughly five occasions—a true testament to the quality of our dealers and their dedication to your happiness.
Our dealers are highly experienced in packing and shipping fragile, high-value antiques. Because you are in direct contact with the dealer, you will be able to easily go through all available shipping and insurance options together to ensure your item arrives safely.
Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

Siebe Gorman & Co was a prominent British engineering firm that pioneered standard diving dress and deep-sea diving equipment from the nineteenth century onwards.

Standard deep-sea diving helmets were constructed primarily from heavy-gauge spun copper domes fitted with cast brass viewports, valves, and breastplates.

Authentic helmets feature heavy metal construction, stamped serial numbers on the neck ring and breastplate, and cast brass maker plaques.

A copper diving helmet serves as a focal statement piece when displayed on an office desk, mantelpiece, or bookshelf within an industrial or dark academia scheme.

Dust gently with a soft microfibre cloth and avoid harsh chemical cleaners to preserve the natural surface patina and verdigris oxidisation.
