Celtic inspired and Scottish glass agate costume jewellery is very distinctive , with the designs often based on earlier Victorian and pre-antiquity pieces. Made from glass stones (created to imitate the agates) which are set into non-precious mixed metal, they are a beautiful mix of intricate patterns and bold statement features.
Notable makers are Miracle and Heathergems (who ingeniously use compressed real heather found on the Scottish moors to create stones,) though collectors might also come across vintage producers no longer in business, such as Jacobite and Hollywood; look for ‘signatures’ and makers stamps on the back of the jewellery as often (but not always) jewellery might be signed.
Telling the difference between modern Celtic inspired and Scottish costume jewellery and older ‘real’ antique agate jewellery can be tricky at first. As a general rule, antiques tend to be more delicate and intricate in nature; look for fine etching, flush stone settings and top quality scroll patterns. T-bar pins and long pins are a sign of antique brooches too (see here for my guide to dating antique brooches for more info). Antique Celtic inspired and Scottish jewellery is made from real agates and gemstones.

More modern Scottish costume jewellery dates from circa 1950s to today, and is usually made from glass, enamel or other imitation ‘stones’. The pieces tend to be much chunkier, and often include thistles and Celtic knot work patterns (surprisingly, real Victorian antique Celtic and Scottish jewellery rarely shows thistles or Celtic knot patterns, instead using popular Victorian era scroll patterns of the time instead).

ABOVE: a more modern costume jewellery circa 1980s glass agate brooch. Notice the chunky stone settings, Celtic patterns and ‘mottled’ stone colours of the glass (which is trying to imitate agates.
Here are some of my favourite Celtic inspired and Scottish costume jewellery designs:

Beautiful simple Celtic cross brooch, with brown banded glass stone, made circa 1980s. A sign of more modern Celtic inspired and Scottish jewellery is the use of the cross in the design, along with Celtic patterns.

Some costume Scottish or Celtic inspired brooches do have gemstones set into them (such as this quartz), though note the metal is still mixed/non-precious, as seen in this lovely modern brooch.

Gorgeous circa 1970s Scottish inspired brooch. Whilst the patterns are intricate, the stones (made from glass) are glued in quite crudely, and not flush set.

Unusual Celtic glass agate brooch, set into imitation gold colour metal.

Chunky, bold and vivid colourful design – a hallmark of more modern Scottish agate glass inspired brooches.

Stunning circa 1950s glass stone brooch.

Lovely penannular style brooch, made from mixed metal and glass. Genuine penannular brooches are a type of cloak fastener rather than decoration brooch – though note the costume jewellery designs (such as this one) are decoration only, and don’t work!

Magnificent Scottish glass agate costume jewellery brooch, set in bronze colour metal.

Whilst brooches are the most popular type of Scottish and Celtic inspired costume jewellery, pendants, bracelets and rings are made too.
