If you want sparkle, but prefer an understated look, then marcasite gemstone jewellery may be perfect for you. These semi-precious stones are a type of mineral, which range in colour from silver-yellow to bright white silver. When faceted and set into jewellery, they create a subtle sparkling effect, rather than a full on glitz – perfect for adding a hint of shimmer.
Above, a varied selection of vintage marcasites, harvested from old broken jewellery. Notice how some are flat-backed (near the back), and some are the traditional ‘diamond’ shape, depending on the setting of the jewellery they came from. Marcasites generally vary in size from approx 0.5mm to 1.5mm. They are seriously tiny!
Marcasites next to my pinky finger!
Marcasites can be set into all types of jewellery, and were a popular gemstone to be used in art deco rings.
Marcasite necklaces have been worn since the 19th Century, and are still hugely popular today. This vintage beauty dates from around the 1960s.

Marcasites can sometimes develope a yellow/ brown colour over time, as seen in this adorable vintage circa 1970s bow brooch – this is simply age and nothing to worry about 🙂
Had normal glitzy glass paste rhinestones been used to frame this lovely carved shell cameo, they would have detracted from its beauty. Marcasites however, are perfect for giving a crisp finish without over awing the jewellery itself.
Flower basket brooches were hugely popular in the 1950s – some were plain or set with rhinestones, while others were encrusted with diamonds and coloured gemstones (depending on your budget!). Marcasites are the happy medium between costume jewellery and fine jewellery, and suit most budgets.
This outstanding marcasite flower brooch has been ‘cold painted’ with enamel (ie, using a paintbrush and enamel paint, rather than more complex true vitreous enamel work which involves firing powdered glass in an oven). Cold painted marcasite enamel jewellery was popular during the 1950s to 1970s, and on a personal note, is one of my all time favourite types of vintage jewellery – it transcends ‘accessory’ and becomes ‘art’.

These marcasite bird clip on earrings look like they could have been made recently – but they actually date from the 1950s. Cuteness never goes out of style 🙂
While a couple of stones missing from vintage marcasite jewellery is quite normal, any more and I consider it damaged and in need of repair (with prices to reflect this.
Repairing marcasite jewellery yourself is tricky, but can be done with a steady hand and the right tools. Firstly, you need a good stock of marcasites harvested from other broken jewellery (or buy some online). Match up the sizes to the rest of the marcasites in the jewellery you wish to repair. Next, get yourself some proper ‘jewellery cement’ such as “GS Hypo Cement” – it’s a strong clear specialist jewelry glue that has a super fine nozzle – perfect for tricky work (never use superglue – it dissolves marcasites, as I found to my horror many years ago at my first attempt at marcasite fixing!). Put a tiny dab of cement in the hole you which to place the stone in, and then pick up the marcasite by pressing your finger on it – the natural moisture on your finger will temporarily hold it on. Finally, place it in the hole, and adjust with a pin if needed. This is tricky work, and it may take a few attempts before you get it right.

Spotting faux marcasite jewellery can be hard work, especially because modern real marcasite jewellery can look very similar to vintage faux marcasite jewellery! A good giveaway is the weight – vintage faux-marcasite jewellery, as seen in this cute pony brooch, was made from a metal called Eloxal (a type of aluminium) which was very light in weight – almost weightless! (Vintage Eloxal jewellery was usually made in West Germany and occasionally East Asia, and was popular during the 1960 and 70s because it never tarnished or discoloured). Grab a magnifying glass and have a good look at the stones – if they appear too ‘perfect’ and flush set, it could be faux marcasites (real marcasites are a pain to set straight, and are often even purposely set slightly crooked to give better sparkle and depth to the whole piece of jewelry).
A beautiful Celtic inspired vintage circa 1970s faux marcasite panel Eloxal metal bracelet. Two give-aways in identifying the jewellery was its weight (almost weightless when held – a signature of vintage Eloxal metal), and the uniform shape and settings of the ‘stones’. Vintage Eloxal jewellery is a collectable in its own right, and I absolutely love this bracelet!
