Strictly Vetted Dealers

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.

The Sustainable Choice

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.

FAQs

A crossover ring, also known as a bypass ring, features a band that wraps around the finger with overlapping ends rather than meeting at a central point. This style emerged in the nineteenth century and gained significant popularity during the mid-twentieth century for fluid, asymmetric gemstone settings.

Jewellery from the 1960s frequently combined precious metals such as platinum, white gold, and yellow gold. Central gemstones like sapphires, rubies, and emeralds were commonly paired with structured diamond cuts, particularly baguette and tapered baguette shapes in channel settings.

Authentic mid-century pieces often display specific structural characteristics, including dynamic fluid bands, mixed-metal claw construction, and precise channel-set secondary stones. Look for period assay marks, hallmarks, and heavy wirework undercrafting typical of 1960s manufacture.

A vintage crossover ring serves as a focal statement piece due to its architectural form and vibrant colour. It pairs effectively with clean-lined modern tailoring, neutral evening wear, or stacked alongside minimal fine metal bands.

Clean gemstone rings using warm water, mild detergent, and a soft-bristled brush to remove accumulation under the settings. Periodically inspect claw settings and channel tracks with a jeweller to ensure stones remain securely mounted.
