What it does
This server exposes moissanite grading reference data and density-corrected conversion tools for carat-to-millimetre calculations, ring sizing across US/UK/EU standards, and jewellery fitting estimates. It is for developers building jewellery tools or e-commerce applications who need accurate moissanite specifications.
- Convert between carat weight and millimetre diameter for moissanite, accounting for its different density than diamond.
- Look up GIA grading scales for colour and clarity, and retrieve optical properties for moissanite, diamond and cubic zirconia.
- Convert ring sizes across US, UK, and EU (ISO 8653) standards, and estimate how necklaces and studs appear on the wearer.
Tools this server exposes
| Tool | Does |
|---|---|
| carat_to_mm | Convert carat weight to millimetre diameter for a specified stone type (moissanite, diamond, or cubic zirconia). |
| mm_to_carat | Convert millimetre diameter to carat weight for moissanite, diamond, and cubic zirconia in parallel. |
| grading_scale | Retrieve GIA colour and clarity grade definitions, and optical constants for different stone materials. |
| ring_size_convert | Convert ring sizes between US, UK, EU, and millimetre inner diameter standards. |
| necklace_length | Return where a necklace of specified length sits on the body (e.g. collar, chest, waist). |
| stud_appearance | Estimate how a stud of given millimetre size appears on the ear relative to other reference sizes. |
Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
