Hair. Hair is not popular in jewellery these days except perhaps a snip inside a locket. Back in the Georgian and Victorian eras hair jewellery was very common in fact there was an entire industry built up around it . There is both hair inside lockets and also pieces of jewellery made out of plaited and woven hair including bracelets and watch chains.

Hair Pin A brooch like ornament with a clip on the reverse so that it can be worn in the hair.

Half Pearl Pearls and cultured pearls cut in half so that they can be set flat into jewellery such as brooches

Hallmarks The marks impressed into jewellery to show how old the piece and the purity and type of metal. Hallmarking in the UK is strictly controlled and is your jewellery guarantee.

Hammer finish. A textured finish normally applied to copper, silver or pewter. It was very popular in arts and crafts jewellery.

Hand Jewellery Pieces in the shape of a hand. The fingers can be pointing or perhaps the thumb and first finger touching. Often the hands have a decorative cuff. The hand may have its own miniature bracelet or rings. I have seen hands holding miniature baskets of flowers which are most attractive.

Hardness .The harder a gemstone is the longer lasting it will be in a piece of jewellery, it will be less prone to wear. Diamonds are the hardest of all gemstones with Sapphires and Rubies the next in line. Hardness is measures by Mohs scale.

Hardstone. This is a generic name given to opaque stones which can be carved and polished to use in jewellery. These include agates, onyx and carnelians.

Hat Pin A pin used to secure a hat in place. There is a long metal pin and a decorative finial. They were used from the Victorian era until the 1930s. Pins in the Victorian era tended to be longer than those in the 1920s and 1930s.

Heart The heart shape is one of the most enduring in jewellery. It can be a plain heart shape, double hearts or hearts entwined. There are specialised shapes such as the Witches heart and the Luckenbooth. Especially popular as a gift between loved ones.

Heat Treatment Natural gemstones can be heated to enhance their colour.

Heliotrope Another name for bloodstone, It is a dark green hardstone with red flecks in.

Hematite A hard shiny black gemstone

Hoop, The part of the ring which goes behind the finger officially known as a shank. There are also hoop earrings which are circles around the ear lobes.

Horn Animal horns carved, heated and shaped into jewellery. Very popular during the Victorian era for brooches and buckles. Clearly horn jewellery is not ethical similarly to ivory.

Hungarian Jewellery Jewels made in Hungary,    we see little of the early jewels but great pieces from the Victorian era and early 1900s do turn up from time to time. These are often made of gold and silver in fantastical shaped and can include enamel and gemstones. They are usually quite bold pieces of jewellery in complex patterns.
