概覽

AI 產生的概覽

遠端 MCP 伺服器，為助理提供七種寶石的寶石學資料：性質、依讀數比對、比較與吸收光譜。

可以做什麼
  • 查詢單顆寶石的常數、多色性與光譜，以及折射儀、偏光鏡與二色鏡的觀察結果
  • 用折射率、雙折射、比重、光性特徵或光譜線等測試讀數與七種寶石比對並排序
  • 並排比較兩種寶石，說明哪些測試能區分它們
  • 讀取手持分光鏡下該寶石的吸收線與吸收帶及其成因
適用情境
適合在已有儀器讀數或懷疑某顆寶石時，用來縮小候選範圍，或了解哪些測試能區分鑽石與莫桑石等相似寶石。它是參考輔助，不能取代實驗室報告。
執行需求
需要一個遠端 Streamable HTTP 端點；無需登入、API 金鑰或本機執行環境。README 將寶石鑑定端點與切工庫、課程伺服器分開列出。
安裝前請注意
僅涵蓋七種寶石，比對結果只是線索而非鑑定結論，實驗室報告才是證明。此伺服器聲明為唯讀且免費使用，不要求任何憑證。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Digital Gemology: gem identification and gemstone properties，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/com.digitalgemology%2Fgem-identification/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

Gemology lessonshttps://digitalgemology.com/mcp/learncom.digitalgemology/gemology-lessonsSearch, read and quote 53 gemology lessons: the four Cs, diamond anatomy, grading reports, diamond vs moissanite, historic cuts, bow-ties
  • 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)

ToolWhat it does
search_cutsSearch 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_cutEverything 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_gemstoneThe top ten brilliants and top ten jewelry cuts in one gemstone, with the stone's optical constants.
cut_in_gemstoneHow one cut performs in one gemstone: eight measured scores against the T73 round brilliant, with pros and cons.
list_gemstonesThe seven gemstones (diamond, moissanite, cubic zirconia, ruby, sapphire, emerald, amethyst) with refractive index, critical angle, dispersion, hardness and specific gravity.
get_cut_scoresThe Cut Performance Index: overall, brilliance, fire, scintillation, tilt, symmetry, spread, shape-norm and leakage, in all seven gemstones.
compare_cutsTwo cuts side by side in one gemstone: place in the index, every figure, which cut is ahead on each, and links to buy.
recommend_cutThe 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.

ToolWhat it does
gem_propertiesOne gemstone: refractive index, birefringence, dispersion, specific gravity, hardness, crystal system, and what each instrument shows.
identify_gemGive 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_gemstonesWhich tests tell two gemstones apart (for example diamond and moissanite), and which do not.
absorption_spectrumThe lines and bands a gemstone shows in a spectroscope, with their cause.

Gemology lessons tools (/mcp/learn)

ToolWhat it does
search_lessonsFind lessons on a topic or question ("what is fire in a diamond").
get_lessonThe full text of one lesson as Markdown, by title or URL.
explain_termShort passages from the lessons that explain a term ("critical angle", "pavilion angle"), each with its link.
list_coursesEvery course and its lessons.

Data

data/ holds the Digital Gemology Cut Performance Index: ray-traced light-performance scores for 45 gem cuts in seven gemstones, diamond, moissanite, cubic zirconia, ruby, sapphire, emerald and amethyst (315 rows). 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.

gem_properties

Gemstone properties

Everything 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 and the lines and bands a hand spectroscope shows, with links to the free tools.

輸入參數gemstone必填

identify_gem

Match gem test readings

Match 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 read over the limit. A match is a lead among seven stones only, not an identification.

compare_gemstones

Tell two gemstones apart

Two 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 tell diamond from moissanite?'.

absorption_spectrum

Absorption spectrum

What 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.
