Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.

Condition

This stunning antique sapphire and diamond line bracelet is excellent quality, set with impressive sapphires displaying fine colour and brilliance; under magnification some surface wear is visible, this does not detract from the aesthetically pleasing appearance.

The diamonds display a fine white colour and brilliance.

The bracelet is an excellent gauge of platinum and is in excellent condition, with a clear hallmark to the tongue.

Reflections in photographs may detract from the true representation of this stunning example of antique sapphire jewellery.

This Art Deco line bracelet dates from 1930 and belongs to the period of 1930s sapphire jewellery. The piece is fashioned in platinum with a silver colour finish, displaying a repeating alternating pattern of deep blue square faceted cut sapphires and white Old European round cut diamonds set within box settings. Fine decorative elements include milgrain borders framing the stones and an integrated push fit clasp secured with a hinged safety catch. The hallmark reads PT on the tongue. Surface wear is visible under magnification. The bracelet measures 17.4 cm deep, 0.333 cm wide, and 0.307 cm high. In a modern home, this line bracelet is worn for everyday luxury and formal evening occasions as part of a personal jewellery collection. The piece functions as a wearable heirloom accessory that secures around the wrist. It suits dressing tables and jewellery boxes for storage when not in use.

Art Deco line bracelets, popularised during the 1920s and 1930s, feature a continuous linear band of repeating, symmetrically set gemstones. These pieces emphasize clean geometric lines, platinum mountings, and square or calibre-cut stones.

1930s line bracelets were primarily crafted from platinum due to its strength and neutral colour, paired with diamonds, sapphires, rubies, or emeralds. Gemstones were frequently cut into square, baguette, or calibre shapes to fit precise geometric mountings.

Authentic period pieces feature hand-cut calibre gemstones fitted tightly into individual box settings, fine milgrain detailing along the edges, and period-appropriate platinum hallmarks or makers marks.

When not being worn, an antique line bracelet can be displayed on a dark velvet jewellery tray inside a glass cloche or placed atop a dressing table vanity dish.

Clean the bracelet gently using warm water, mild dish soap, and a soft-bristled brush to clean around the settings. Store the piece flat in a soft fabric pouch to avoid scratching adjacent gemstones or metalwork.
