Platinum and Diamond Brooch
When you search for a platinum and diamond brooch, you enter a world of fine craftsmanship defined by period elegance and precious metals.
Platinum and Diamond Brooch
A platinum and diamond brooch combines the strength and white sheen of platinum with the brilliance of cut diamonds, often taking the form of bar brooches, floral clusters, or geometric Art Deco shapes. These pieces span several decades, including Edwardian, Victorian, Art Deco, and mid-century periods, reflecting the shifting tastes in jewellery design from delicate lacework patterns to bold, streamlined geometry.
The most common examples you will encounter on this page date from the 1920s and 1930s, embodying the geometric symmetry and fine millegrain work characteristic of the Art Deco era. Alongside pure platinum settings, many pieces integrate combinations of 18ct white or yellow gold, sometimes paired with gemstones such as emeralds, rubies, sapphires, onyx, or pearls.
Beyond standard dress pins, the selection includes versatile pendant brooches, convertible double-clip designs, and themed motifs ranging from equestrian racing scenes to flying ducks and crescent moons. These jewels were originally pinned to lapels, evening gowns, or hats, serving as both ornamental focal points and status symbols for their wearers.
Materials and Techniques
Platinum emerged as the preferred metal for fine jewellery during the Edwardian and Art Deco periods because its remarkable tensile strength allowed goldsmiths to forge delicate, wire-like settings that held stones securely with minimal visible metal. Craftsmen frequently combined platinum with 18ct gold or platinum-topped gold bases to harness the structural benefits of both materials.
Gemstones were cut by hand, yielding old mine cuts, old European cuts, and transitional cuts that exhibit softer light dispersion than modern brilliant cuts. Artisans accented these diamonds with contrasting materials including black enamel, calibre-cut onyx, deep red rubies, and green emeralds, often finishing edges with precise millegrain beaded borders.

Platinum and Diamond Brooch: Frequently Asked Questions
How do I wear a vintage brooch today?
These pieces pin securely onto jacket lapels, heavy wool coats, scarves, or the shoulders of evening dresses. You can also thread certain designs onto a chain to wear them as pendants.
For convertible items like double clips, you can separate the components to wear on two lapels simultaneously or join them back together for a statement centrepiece.
Are these brooches suitable for daily wear?
Platinum is an exceptionally durable and wear-resistant metal, making these items robust enough for regular use. However, the delicate settings and antique gemstones require mindful care.
You should avoid wearing them during physical activities or housework to protect the delicate millegrain work and prevent stone loss.
How do I tell an Edwardian brooch from Art Deco?
Edwardian pieces date from the early 1900s and lean towards organic, garland, and lace-like motifs inspired by nature, utilising platinum-topped gold and old-cut diamonds. They often feel lighter and more ethereal in their construction.
Art Deco items emerge in the 1920s and 1930s, favouring strict geometric lines, symmetry, strong colour contrasts with onyx or enamel, and pure platinum settings.
What is a platinum-topped gold brooch?
This construction method involves bonding a thin sheet of platinum to the front of an 18ct gold base structure. Goldsmiths used this technique before platinum working techniques were fully developed or to reduce the overall weight and cost of the item.
The front face presents the bright white surface required for diamonds, while the gold reverse provides hidden structural support.
