SI: Refined Obsidian
Refined Obsidian adds a full set of obsidian building blocks, styled after the deepslate family, to the game through Fabric, Forge and NeoForge.
What it does
The mod gives obsidian its own family of decorative blocks: cobbled, polished and bricked variants, tiles, stairs, slabs and walls, plus a chiseled obsidian block. The blocks resemble the deepslate set in shape and their colors follow obsidian's dark purple tones. Players craft them from obsidian to build with a consistent material.
A new armor trim material called obsidian dust is also added. It applies to armor the same way vanilla trims do, so an obsidian trim can be placed on any suitable piece. Required dependency: Fabric API, which must be installed on Fabric. Environment: the server and every player need the mod. Released under a custom license and not open source; the files cover 1.20.1, 1.20.4 and 1.21.1.

Obsidian armor trim
Obsidian dust becomes a trim material that armor can use in the smithing table, like other trims.
Deepslate-style set

How it compares
Colored Obsidian is a Fabric-only mod for 1.20.1 – 1.20.4 that is server-side only and not open source, so clients need nothing installed. Dynamic Trim is open source under the MIT License and runs on Fabric, Forge and NeoForge for 1.20 – 1.21, but only on the client. Refined Obsidian needs both sides and covers the 1.20.1 – 1.21.1 range.
