Medieval Gemstones

 Medieval people valued gemstones.  They were widely used metaphorically, as, for example, the Heavenly Jerusalem had its walls studded with gems, or a larger-than-life hero in an epic tale would have jewels set in the hilt of his sword.  But they also used both precious and semi-precious stones to decorate everything from Bible covers to royal crowns to reliquaries to communion cups.

Although these days few churches would stud their holy objects with gems, medieval people did so regularly.  Just as crown jewels marked the high position of a king or queen, so gemstones attached to the reliquary that held the bones or other relics of a saint marked this saint as something very special.

The above image is the twelfth-century reliquary of Sainte Foy, patron saint of Conques, apparently at origin a Roman statue of a man (Foy was a woman), repurposed to hold Foy's relics and covered with gems to show her value.  Many of these gems may have come from jewels people donated to show their gratitude to Foy when she healed them (she was particularly known for healing blindness and diseases of the eye).  In the stories, if someone came to be healed but carefully left their rings at home (so Foy wouldn't claim them), their hands would swell unbearably the next time they wore the withheld rings.  A quick return visit to Conques would be needed.

Gemstones could also have what we would call magical powers.  The proper gem placed under the tongue, or dipped in liquid that one then drank, or placed on the body could supposedly heal disease, or reveal a secret (like adultery), or protect travelers, or help a mother in childbirth.  It was agreed that these gems might lose their potency with time, so there are accounts of priests blessing them or putting them on the altar or anointing them with special herbs to revive their power.

The powerful had much of what we would call their liquid wealth tied up in gemstones.  Women wore highly valuable necklaces, and rings set with jewels were frequent gifts from the wealthy to their closest associates, or gifts made in response to a special service.

Diamonds were extremely rare in the Middle Ages and highly valued; most diamonds in more modern times have come from deep African mines.  Other precious stones included rubies, emeralds, sapphires, opals, and amethysts, plus pearls, which are actually not stones at all, although they are minerals.  Most of these precious jewels can now be created in the laboratory, but of course they were not then.  Medieval people also valued what were considered semi-precious stones (the distinction between precious and semi-precious went back to antiquity), like topaz, lapis lazuli, jade, beryl, and tourmaline.

Medieval jewelry

 Without easy access to African diamond mines, Asian pearl fisheries, and the like (if these even existed then, which they didn't), medieval people had far fewer jewels accessible than do modern westerners, who can walk into a jewelry store and pick something out.  If you like, you can even pay heed to the Diamond Sellers of America (or whatever they're called) and spend six months' salary on an engagement ring.

But medieval people valued jewelry and precious metals just as much as we do, for a combination of their beauty and their rarity.  They had gold and silver but in small amounts, the silver mostly from German mines, and a lot of it old, constantly reused material that went back to the Romans.  Coins were officially silver, though there was always a certain amount of "baser" metal mixed in.  Gold, valued more than silver then as now because it doesn't tarnish, was used for jewelry but rarely for coins.

We tend to think of diamonds, emeralds, rubies, and sapphires, but there are a lot of other jewels out there, a lot of which medieval people valued.  You don't hear as much these days about tourmaline, beryls, chalcedony, peridot, and carbuncles, but these are perfectly good kinds of jewels.  For that matter, carefully cut colored class made a nice jewel equivalent (and still does).

Jewels were worn decoratively by the very rich (as they still are), by both men and women.  Rings were highly valued, both as signs of display and as gifts.  We treat rings today as symbols exchanged between engaged or married couples, but they were also given in the Middle Ages to friends, to faithful followers, and to people who performed a special service.  Jewels could also be made into necklaces, but jeweled rings and brooches were more common, because you needed far fewer stones.

Jewels as signs of prestige of course decorated crowns and diadems.  In the stories, jewels were set into the swords of the elite, but this seems very unlikely.  Every piece of jewelry was of course unique, being hand-crafted from whatever stone or stones the jeweler had to work with.

Both precious metals and precious gems were used to honor God and the saints.  An exceptionally fine Gospel book would be decorated with images using thin layers of gold leaf.  Reliquaries would be decorated with jewels.  As I have discussed before, poverty in emulation of the humility of Christ was considered (potentially) holy, but when it came to glorifying the King of Kings, medieval people didn't hold back.

Reliquaries were embossed with gold and silver, as in this arm reliquary, and precious stones adorned them.  In the post-medieval period, a lot of reliquaries were robbed of their jewels or were melted down for their gold and silver, but we still have some of them in more or less pristine form.

These days churches have gone in a much simpler look, but in the Middle Ages they were meant to take your breath away with their beauty and decoration, including statues, paintings, and jeweled reliquaries.
