Handcrafted Medieval Banner Necklace in Recycled Sterling Silver with Colour Change Stone | One of a Kind

A medieval banner in recycled sterling silver, hanging from a bar and swinging freely the way a real one does, hand engraved with stars and set with a pear cut stone that changes colour depending on the light you stand in. The sterling silver necklace is included and fixed to the piece, 45 cm and complete. There is one of her, and she will not be made again this way.

The Essence

Stars engraved by hand.
A stone that will not commit to one colour.
The house that never gives you a straight answer.

Inspiration & Story

The Mystics Guild Banner belongs to the Nox Ex Libris collection, a realm built from books, medieval revival, knightcore and the kind of fantasy you disappear into on purpose.

Where her sister banners carry swords or a moon, this house carries a stone that changes its mind. Engraved stars scatter across the field, with a pear cut colour change stone set at the centre. Which is the correct arms for a guild of mystics, because you can look straight at it twice and get two different answers.

The stone is alexandrite coloured synthetic corundum, and we would rather use the long name than the short one. Corundum is the mineral family that contains ruby and sapphire, and this is lab-grown corundum engineered to imitate the colour change of natural alexandrite. It is not alexandrite, which is a different mineral entirely, chrysoberyl, and one of the rarest and most expensive coloured stones on earth. Almost everything sold as affordable alexandrite is exactly what this is, and most sellers simply write alexandrite and let you assume. We are telling you.

What you get is genuinely lovely. The colour change effect is real: the stone reads cooler and more violet-blue under daylight and shifts warmer and more purple-red under lamplight and candlelight. The physics is the same as in natural alexandrite, just achieved deliberately rather than by geological accident. Held under one light it is one stone. Walk into another room and it is another. And because it is corundum, it sits at 9 on the Mohs scale, second only to diamond, which makes it far tougher than most stones you could put here.

She is a banner, built properly. The silver field hangs from a horizontal bar and swings on it, which is the whole reason she works: a banner that cannot move is a plate. She turns as you walk and catches light differently every time.

Heraldry was never decoration. A banner told you, from a distance and often before anyone spoke, whose side someone was on. In a period when most people could not read, a field with a mark on it was a functioning identity. Wearing one is a small declaration of allegiance, which is why it belongs in a bookish collection. Everyone who reads deeply has a house, an order, a guild they would have joined.

All of the engraving is done by hand, cut into the metal with a graver, and it carries the variation of a hand rather than a machine. That is deliberate and historically correct: a real medieval banner was painted or stitched by a person, so no two lines matched and no two banners from the same house were identical. A perfectly uniform line would be the anachronism. Hand engraving is also the one process on our bench with no second attempt, because a graver removes metal and metal does not come back.

Everything is made in our own atelier in the Netherlands, in real recycled 925 sterling silver. No plating, no filled, no vermeil, explained honestly in solid gold vs gold filled vs vermeil vs gold plated. If you want the wider case for why readers wear their books, bookish jewelry, why romantasy readers wear their stories is the one, and how to spot genuinely ethically made handcrafted jewelry will make you considerably better at reading listings, including ours.

Perfect for lovers of heraldry and medieval banners, colour change stones, celestial jewelry, knightcore and medieval revival, romantasy and bookish jewelry, hand engraved work, LARP and RPG aesthetics, renfaire and castle festivals, and one of a kind sterling silver jewelry.

This is a One of a Kind creation. There is one of her and she will not be made again in this form. Her sister banners are The Midnight Guild Banner with a sapphire, The Bloodletter Guild Banner with a garnet, and The Lunar Guild Banner with a labradorite. Four houses.

Crafted using in-house digital and traditional techniques: 3D designing, 3D printing, casting, sawing, shaping, soldering, hand engraving, bezel forming, stone setting, blackening and polishing.

Every engraved line and star was cut into the metal by hand with a graver, with no way to correct a cut once made. The bezel was formed around this particular stone, the banner is built to hang and swing on its bar rather than being fixed flat, and the blackening was worked into the engraved lines and polished back off the surface so the stars read clearly.

Style & Wear

A heraldic statement for medieval revival, romantasy and celestial baddies.

At 25 x 21 mm on a 45 cm chain she sits high on the chest, roughly at the collarbone, which is where a banner should be: visible, and reading like something worn on a tabard rather than hanging low as an ornament.

At 10.24 g she is the heaviest of the four banners, so she has real substance to her in the hand.

Because she swings on her bar, she wants a bit of open neckline rather than being flattened under a high collar. And she is genuinely a different necklace depending on where you are. Cool and violet-blue in daylight, warmer and more purple-red under a lamp or candlelight. Which makes her the one to wear somewhere you will move between rooms.

That also means she does not lock into a palette. Cool light pairs her with silver and blue, warm light pairs her with gold and red.

She is one of the easiest pieces on our site to give, because there is nothing else to buy. The chain is on her.

Perfect for renfaires and castle festivals, romantasy fairs, LARP weekends, a book release you queued for, and every day you want your allegiances visible and slightly ambiguous.

Questions & Answers

Is the necklace included?
Yes. Unlike our pendants, the sterling silver necklace is part of this creation and is fixed to the piece. It arrives complete at 45 cm, with nothing further to buy.

Is this real alexandrite?
No, and we would rather say so plainly. It is alexandrite coloured synthetic corundum: lab-grown corundum, the same mineral family as ruby and sapphire, engineered to imitate the colour change of natural alexandrite. Natural alexandrite is chrysoberyl, a completely different mineral, and one of the rarest and most expensive coloured stones in the world.

Why do so many listings just say alexandrite then?
Because it sells better and most buyers do not know the difference. Almost all affordable alexandrite on the market is exactly what this is. If you ever see natural alexandrite at a low price, the honest assumption is that it is not natural alexandrite.

Does it really change colour?
Yes, and the effect is genuine. It reads cooler and more violet-blue under daylight and shifts warmer and more purple-red under lamplight and candlelight. The physics is the same as in natural alexandrite, engineered deliberately rather than formed by geological accident.

Why does a stone change colour at all?
Because different light sources contain different mixes of wavelengths. Daylight is richer in blue, incandescent light is richer in red. A stone with the right chemistry absorbs light unevenly enough that the balance tips one way in one light and the other way in another.

Is it durable?
Very. Corundum sits at 9 on the Mohs scale, second only to diamond, which makes this stone tougher than the garnet, amethyst or labradorite in her sister banners.

Does the banner really move?
Yes. It hangs from its bar and swings freely, so it turns as you walk and catches light differently each time. A banner that cannot move is a plate.

What is heraldry actually for?
Identification. A banner told people from a distance whose side someone was on, which mattered enormously in a period when most people could not read. A field with a mark on it functioned as an identity.

Is the engraving machine made?
No. Every line and star is cut into the metal by hand with a graver, which is why they carry the variation of a hand rather than the uniformity of a machine. That is deliberate and historically right, since a real medieval banner was painted or stitched by a person and no two were identical. Engraving also has no second attempt: a graver removes metal and metal does not come back.

Is there a matching piece?
Yes, three. The Midnight Guild Banner carries a sapphire, the Bloodletter Guild Banner a garnet, and the Lunar Guild Banner a labradorite. Four banners, four houses, all built the same way.

Will sterling silver tarnish?
Yes, all sterling silver does. Normal reaction to air and skin, not a fault. On an engraved piece it helps, since tarnish in the cut lines is what makes the stars read. Your upkeep document explains how to clean her without lifting the blackening out of the lines, and a soft brush is better than a cloth here.

Can you make me one of these?
Not this one. If you want a banner with your own arms or engraving on it, that is exactly the sort of thing our Custom Realm exists for.
