Sapphira Gemweaver had fifty-eight days left to open her shop, and this morning her workbench sat empty again. Three apprentices should have been polishing garnet, stripping silver wire, feeding the outdoor hearth. Instead she found their aprons folded on the stools and the back gate swinging on its hinge. She heard the music then, thin and sweet, drifting from the trees past the garden wall. It was the same tune that had stolen them yesterday, and the day before. She walked out to her forge platform and banked the fire higher. The hearth she used was not a shop forge. It sat under open sky, ringed in carved runes, stacked with crucibles and vials of quenching oil. She fed it until the coals ran white, hotter than any other jeweler in Nightbloom would risk. At that heat, a gem sank into its setting and became one thing with the metal. It was the trick that had built her name, and the reason a widow had slept through the night wearing her black opal. She had chosen this city because it held enough darkness to want light. She did not miss deadlines. Above the workyard, her display frame swayed under finished pieces: pendants, rings, a collar of moonstones that made passersby glance over their shoulders. It was meant to draw customers. Now it only creaked while the shop stood still. She followed the music to its source. In a clearing past the wall stood a small pavilion of stained glass, panels humming, notes leaking through the seams like colored smoke. Her three apprentices stood inside with their palms on the glass. A mushroom sprite crouched on the roof, gray-skinned, sharp-toothed, watching the road. When it saw her, it grinned and played on. Two strangers wandered in from the far path and pressed their hands to the glass beside her apprentices. Sapphira understood then. The song did not want workers. It wanted anyone who walked near. She went back to the forge. She chose granite for the body, and from her scrap tray she picked every stone that answered heat: ruby, tourmaline, jade, a chip of the same black opal. She worked through the night. She carved a standing figure, a witch in a wide hat with a staff, and she fused each gem into the stone at a temperature that would have cracked another maker's work. She cut runes along the base for silence, for shelter, for a mind that stayed its own. By dawn the figure stood taller than she was, and the stones in it caught the first light. She hauled the idol to the edge of the clearing on a plank cart. The moment she set it upright, the music thinned. Her apprentices blinked, stepped back from the glass, and looked at their hands as if they had forgotten them. The strangers wandered off down the road. On the pavilion roof, the sprite bared its teeth and vanished into the trees. Sapphira turned her apprentices toward the workyard. Fifty-seven days. She had a shop to open.

By noon her apprentices were back at their stools, polishing garnet as if nothing had taken them. Sapphira crossed the workyard to her shop. The building stood finished at the front of the lot, timber and stained glass, ivy already climbing the porch beams. Lanterns hung from the eaves, unlit. Fifty-seven days on the list, and the sign above the door read her name in painted letters. Inside, the display cases were empty. She had rings and pendants enough to fill them, but nothing that would stop a wealthy stranger on the street. She stood in the doorway and did the math. Nightbloom had six other jewelers within a short walk. Two of them served the palace. A shop opened without a centerpiece to draw the eye would open to no one. She needed one piece large enough to pull the rich down her lane, and she needed it before the wood of the counters lost its new smell. She went out to the forge platform and laid her scrap tray on the runed table. Ruby, tourmaline, jade, a spray of small sapphires, three cut emeralds she had saved for a commission that never came. Not enough. Not for what she meant to build. She thought of hiring out for stones and dismissed the cost. Then she thought of the beetle. The Gemwing lived in the rotted stump behind her woodpile. She had left it there the winter before, when she found it half-drowned in a rain barrel. Its shell grew small stones as it fed. She had never harvested from it. Now she carried a cloth and knelt at the stump and coaxed it out with a smear of honey. It climbed onto her palm, shell bright with new growth. She pinched the ripe stones free one at a time. The beetle did not flinch. When she was done she had a handful of gems no jeweler in the city could match for color. She worked two days at the forge. She chose granite again, because granite had already proved it would hold her heat. She carved a standing witch, taller than the one that broke the sprite's song, and she set every stone the beetle had given her into the robe and the hat and the base. She cut runes for welcome, for trust, for a room that felt safe to open a purse in. She fused each gem at the temperature only she used. When the figure cooled it stood in the front window of the shop, one hand raised, eyes closed. By the third morning a small crowd had gathered on her lane. A woman in silk stepped inside and asked the price of the pendant at the witch's throat. Sapphira named a number. The woman paid it. By dusk two more buyers had come. Then a man in a gray cloak stopped at her window. He did not come in. He studied the idol a long time, and then he turned and walked back the way he had come.

By the end of the week the front room stayed busy from open to close. Sapphira sold three rings, a pair of earrings, and a garnet cuff to a merchant's wife. Then a footman in palace livery came to the door. He looked at the counters, at the apprentices, at the open floor, and asked where a lady might be measured in private. Sapphira had no answer. The footman bowed and said his mistress would send word. He did not come back that day. She stood in the shop after closing and saw the problem plain. The stone witch pulled people in from the lane. The stained glass and the lanterns held them at the window. But once inside, every eye in the room could see every finger and every throat. No woman with a title would let a stranger watch her try a necklace. Fifty-three days on the list. Six other jewelers in the city, and two of them already served the palace behind curtained doors. She walked the shop and measured with a string. The back wall held a storeroom she used for crates. She pulled the crates out onto the workyard that night. By lamplight she and her two steadiest apprentices tore down the shelves and swept the boards clean. The room was small but square. A door, a window high in the wall, four walls of good timber. She worked the next two days at the forge platform. She built a fitting cabinet from oak and stained glass, tall as a man, with a hinged panel that opened to a padded bench and a mirror. She set small stones along the frame, cut from the beetle's shell that morning, and burned runes into the wood for quiet and for trust. She fused each gem at her own heat so none would fall. She hung a velvet curtain across the storeroom door and set a brass bell on the counter for the front. On the third morning a carriage stopped at her lane. A woman in a hooded cloak came in with two guards. She did not give a name. Sapphira rang the bell, sent the apprentices to the yard, and led the woman past the curtain. The woman opened a pouch and poured six loose stones onto the bench. She wanted a collar, she said, for a wedding no one would announce. Sapphira named a price and a date. The woman paid half in gold and left by a side gate the guards had already found. By dusk two more veiled clients had come and gone. Sapphira wrote the commissions in her book. Then she looked at the list of stones the first woman had left, and at the seal pressed into the wax of the deposit purse, and understood she had taken work the crown would not want done.

Sapphira spread the six stones from the hooded woman's pouch across her forge table. She sorted them by weight and by fire. Two garnets, a pale sapphire, a chipped topaz, and two clouded quartz. None of them belonged on a royal throat. The wax seal from the deposit purse sat beside them, pressed clean with the crown's mark. Fifty days left on her list. A wedding collar without a center stone was no collar at all. She wrote the client a short note asking for one more stone, worthy of the piece. The answer came back within the hour by the same silent footman. There was no more coin, no more time, and no more stones. The client had brought what she could steal from her own jewel box without being noticed. The rest was Sapphira's problem to solve. Sapphira went to the back yard and lifted the lid off a wooden crate lined with damp moss. The jeweled beetle climbed onto her palm and turned its shell to the lamp. She had already harvested from it once for the stone witch in her front room. She had promised herself she would let it rest a full season. She broke that promise now. She fed it honey and crushed mica and waited while the shell brightened. By midnight a single gem pushed up through the beetle's back, larger than any it had grown before. The stone came out deep blue, cut clean by its own growth, heavy as a plum. She set it beside the client's six stones. Next to it, the pale sapphire looked like glass. She worked the rest of the night at the forge. She laid the blue stone at the center of the collar and ringed it with the client's garnets and quartz. She brought the metal up past the heat other jewelers used. The gems sank into the silver and fused. When she lifted the collar from the block, nothing rattled and nothing shifted. It held as one piece. At dawn she carried the finished collar through the velvet curtain and locked it in the cabinet behind the fitting mirror. The apprentices came in and swept the front. A veiled client rang the bell for a bracelet fitting. Sapphira served her, took the deposit, and wrote it in the book. The shop ran as it should. She went back to the yard at noon. The beetle lay on its side in the moss, shell dull, legs curled. It was not dead, but it would grow no more stones for her. She closed the crate and stood with her hand on the lid. The collar was finished. The center stone was the last she would ever pull from the creature that had built her shop. She had spent something she could not replace to keep a secret she was not sure she wanted to keep.
