About this game
Management · Lovecraftian · First-personAbyssal Lapidary is a first-person workshop management sim from Light Worm, published by XD. Set in Fathomholm, a Victorian-inspired underground city, you inherit Vermilion House — the fading jewellery shop your missing sister left behind. Buy rough stones of unknown quality, appraise them, strip the host rock, cut facets, set the gems, and sell the results to an increasingly strange clientele.
- 01
Gambling on rough stone
Ore merchants sell lots of mixed quality. Inspect the stone with the monocle before you pay; cheap rough is not automatically worth processing.
- 02
Appraisal and extraction
Rough stone has hardness, toughness, fractures and internal structure. Hammers, chisels, fretsaws and hand drills suit different minerals, and the wrong tool raises the breakage rate.
- 03
Facets and jewellery
The faceting table controls shape, cut and value. The jewellery bench lets you swap mounts, metals and ornament styles, then compare the piece against the commission.
- 04
Commissions and auctions
Commissions are steady income; auctions can fetch a premium. Display cabinets and shop allure gate later progression.
- 05
Awareness and anomalies
Handling strange ores and cutting abnormal crystals raises awareness. Past the threshold, Vermilion House gains whispers, blackouts, tremors and hallucinations.
- 06
The secrets of Vermilion House
Hidden passages, sealed rooms, old ledgers and a room that beats like a living heart point to your sister's disappearance and a buried crime.

FAQ
Can I play Abyssal Lapidary now?
Yes. A free Steam demo launched on 16 October 2026. The full game still shows as coming soon.
How long is the demo?
The community estimate is four-plus hours, roughly 25% of the full game. Actual length depends on how quickly you buy and process stone.
When does the full game release, and how much will it cost?
Neither the release date nor the price has been announced; Steam only says coming soon. Wishlist it and be sceptical of guides quoting a price.
Does it support Chinese?
Yes — Simplified and Traditional Chinese are both supported for the interface and subtitles. The store page does not list full voice-over.
What are the system requirements?
Minimum: Windows 10 64-bit, i5-8400 / Ryzen 5 2600, 8 GB RAM, GTX 1650 / GTX 1060 6GB / RX 570, DirectX 12 and 10 GB of space. Recommended: i5-10400 / Ryzen 5 3600, 16 GB RAM, RTX 4070 / RX 7900 XT.
Will demo saves carry over to the full game?
Not announced. Playtest saves did not carry into the public demo, and there is no official statement yet about demo-to-full saves.
Is it a horror game? Does it use jump scares?
The store page frames it as Lovecraftian psychological horror: pulsing veins, faces in stone, whispers and hallucinations. It does not advertise jump scares, but players sensitive to mounting dread should watch gameplay first.
Is there multiplayer?
No. Steam lists it as a single-player game.
What is awareness?
A hidden value that rises when you handle strange ores and cut abnormal crystals. Past the threshold, Vermilion House gains tremors, blackouts, radio interference, late-night visitors and hallucinations. The exact threshold and any way to lower it have not been published.
