它能做什么

gem_propertiesEverything Digital Gemology measures about one gemstone: refractive index (both rays for doubly refractive stones), birefringence, dispersion, specific gravity, hardness, crystal system, critical angle, what a refractometer, polariscope and dichroscope show, its pleochroic colors
identify_gemMatch a stone's test readings against the seven gemstones Digital Gemology covers and rank them, saying which reading fits and which does not. Give any of: refractive index, birefringence, specific gravity, optic character, pleochroism, a spectrum line, or that the refractometer
compare_gemstonesTwo gemstones side by side, and the tests that tell them apart: refractive index, birefringence (doubling of back facets, polariscope), specific gravity, dispersion (fire), hardness, pleochroism and spectrum, each with the free tool that shows it. For questions like 'how do I tel
absorption_spectrumWhat a hand spectroscope shows for one gemstone: each absorption line and band with its position in nanometres, its cause (for example Cr3+ in ruby) and what it looks like, from Digital Gemology's Spectroscope.

Digital Gemology MCP servers: cut library, gem identification, gemology lessons, glossary
Four remote Model Context Protocol servers from Digital Gemology:
| Server | Endpoint | Registry name | What it does |
|---|---|---|---|
| Cut library | https://digitalgemology.com/mcp | com.digitalgemology/cut-library | Search 40 gem cuts and 5 Platonic solids; ray-traced brilliance, fire and scintillation in seven gemstones; compare cuts; recommend a cut; 3D models and GemCad faceting diagrams |
| Gem identification | https://digitalgemology.com/mcp/gems | com.digitalgemology/gem-identification | Gemstone properties; match refractive index, birefringence, specific gravity, pleochroism and spectrum lines to seven gemstones; tell two gems apart |
| Gemology lessons | https://digitalgemology.com/mcp/learn | com.digitalgemology/gemology-lessons | Search, read and quote 53 gemology lessons: the four Cs, diamond anatomy, grading reports, diamond vs moissanite, historic cuts, bow-ties |
| Gemology glossary | https://digitalgemology.com/mcp/glossary | com.digitalgemology/gemology-glossary | Define 328 gemology terms: every word on a diamond grading report, the four Cs, clarity characteristics, treatments, gem testing, colored gemstones, and how brilliance, fire and scintillation are measured |
- Transport: Streamable HTTP, stateless
- Registry: official MCP Registry
- Sign-in: none. Read-only and free to use.
- Protocol versions: 2026-07-28, 2025-11-25, 2025-06-18, 2025-03-26
This repository holds the servers' public description, their registry listings and the open data they serve. The servers run on digitalgemology.com.
Cut library tools (/mcp)
| Tool | What it does |
|---|---|
search_cuts | Search the cut library by name, style, shape or use ("square step cut", "round brilliant for moissanite", "historic cushion"). Returns each cut's page, facets, size, price and checkout links; give a gemstone to sort by brilliance, fire and scintillation in that stone. |
get_cut | Everything about one cut: measured specifications (facets, angles, depth, size, index gear), brilliance, fire and scintillation in all seven gemstones, prices and checkout links. |
best_cuts_for_gemstone | The top ten brilliants and top ten jewelry cuts in one gemstone, with the stone's optical constants. |
cut_in_gemstone | How one cut performs in one gemstone: eight measured scores against the T73 round brilliant, with pros and cons. |
list_gemstones | The seven gemstones (diamond, moissanite, cubic zirconia, ruby, sapphire, emerald, amethyst) with refractive index, critical angle, dispersion, hardness and specific gravity. |
get_cut_scores | The Cut Performance Index: overall, brilliance, fire, scintillation, tilt, symmetry, spread, shape-norm and leakage, in all seven gemstones. |
compare_cuts | Two cuts side by side in one gemstone: place in the index, every figure, which cut is ahead on each, and links to buy. |
recommend_cut | The best cuts for a gemstone, ranked by overall, brilliance, fire, scintillation, spread, tilt or leakage; filter by category or shape. |
Gem identification tools (/mcp/gems)
The values that Digital Gemology's free Refractometer, Polariscope, Dichroscope and Spectroscope use, for diamond, moissanite, cubic zirconia, ruby, sapphire, emerald and amethyst. A match is a lead, not an identification: a laboratory report is the proof.
| Tool | What it does |
|---|---|
gem_properties | One gemstone: refractive index, birefringence, dispersion, specific gravity, hardness, crystal system, and what each instrument shows. |
identify_gem | Give any readings (refractive index, birefringence, specific gravity, singly or doubly refractive, pleochroism, a spectrum line, over the refractometer limit). Returns which of the seven stones fit each reading. |
compare_gemstones | Which tests tell two gemstones apart (for example diamond and moissanite), and which do not. |
absorption_spectrum | The lines and bands a gemstone shows in a spectroscope, with their cause. |
Gemology lessons tools (/mcp/learn)
| Tool | What it does |
|---|---|
search_lessons | Find lessons on a topic or question ("what is fire in a diamond"). |
get_lesson | The full text of one lesson as Markdown, by title or URL. |
explain_term | Short passages from the lessons that explain a term ("critical angle", "pavilion angle"), each with its link. |
list_courses | Every course and its lessons. |
Gemology glossary tools (/mcp/glossary)
328 terms, each with its own page under digitalgemology.com/learn/glossary. Grading report terms follow GIA, with IGI where it differs.
| Tool | What it does |
|---|---|
define_term | One term ("crown angle", "feather", "fluorescence", "scintillation"): a short definition, more detail, where it appears on a grading report, how Digital Gemology measures it, related terms, and its page. |
search_glossary | Find terms by a word or a question ("what do the girdle words mean", "why does a diamond sparkle"). |
list_glossary | Every term, or every term in one of 15 topics, with a one-line definition and its page. |

Data
data/ holds the Digital Gemology Cut Performance Index: ray-traced light-performance scores for 40 gem cuts and 5 Platonic solids in seven gemstones, diamond, moissanite, cubic zirconia, ruby, sapphire, emerald and amethyst (315 rows; 37 cuts are scored, and the rest are listed with the reason). Ruby and sapphire are both corundum, so they share one set of figures; color and absorption are not part of the trace. The method and every column are explained on the index page.
