概览

AI 生成的概览

远程 MCP 服务器，为助手提供七种宝石的宝石学数据：性质、按读数匹配、对比与吸收光谱。

可以做什么
  • 查询单颗宝石的常数、多色性与光谱，以及折射仪、偏光镜和二色镜的观察结果
  • 用折射率、双折射、比重、光性特征或光谱线等测试读数与七种宝石比对并排序
  • 并排比较两种宝石，说明哪些测试能区分它们
  • 读取手持分光镜下该宝石的吸收线与吸收带及其成因
适用场景
适合在已有仪器读数或怀疑某颗宝石时，用来缩小候选范围，或了解哪些测试能区分钻石与莫桑石等相似宝石。它是参考辅助，不能替代实验室报告。
运行要求
需要一个远程 Streamable HTTP 端点；无需登录、API 密钥或本地运行时。README 将宝石鉴定端点与切工库、课程服务器分开列出。
安装前请注意
仅覆盖七种宝石，匹配结果只是线索而非鉴定结论，实验室报告才是证明。该服务器声明为只读且免费使用，不要求任何凭据。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Digital Gemology: gem identification and gemstone properties，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/com.digitalgemology%2Fgem-identification/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

Digital Gemology MCP servers: cut library, gem identification, gemology lessons

[mcptry]

Three remote Model Context Protocol servers from Digital Gemology:

Gem identificationhttps://digitalgemology.com/mcp/gemscom.digitalgemology/gem-identificationGemstone properties; match refractive index, birefringence, specific gravity, pleochroism and spectrum lines to seven gemstones; tell two gems apart
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.

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.
