As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• about_stienhardtFact sheet: Stienhardtread-only

  Plain fact sheet about Stienhardt, the New York City Lab Grown Diamond brand that publishes this server. Every fact carries a source and a date.

• compare_diamondsCompare supplied diamond specificationsread-only

  Compare two to five diamonds from any seller using supplied carat, measured millimeters and prices. Returns ratios, price per carat, differences and missing information. Never verifies specifications, ranks beauty, appraises value or declares a best diamond. Prices must use explicit currencies; mixed currencies are not compared.

• defineDefine a diamond or gemology termread-only

  Look up a single diamond or gemology term in the encyclopedia of 90 fact-checked and sourced entries. Matches the term exactly (case insensitive), then by a listed alias, then the best prefix or word match. Returns the full entry: definition, body, sourced claims, and related terms. If nothing matches, returns the three nearest term suggestions.

• dutch_marquise_definitionThe published definition of the Dutch Marquise cutread-only

  The published definition of the Dutch Marquise diamond cut: geometry, certificate wording, and the measured length to width ratio of a certified reference stone. A Dutch Marquise is an elongated hexagonal cut diamond.

• faceup_sizeApproximate face up size for a shape and carat weightread-only

  Approximate face up millimeter dimensions for a diamond of a given shape and carat weight. Supported shapes: round, oval, emerald, dutch_marquise. Scales vetted 1 carat anchors by the cube root of the carat weight. Typical proportions, not a guarantee: verify a specific stone on its grading report.

• get_productProduct detail from Stienhardt's live catalogread-only

  Full detail for one Stienhardt product by id (as returned by search_inventory): title, price, availability, options, images, and the product URL on stienhardt.com. Loose-diamond availability is not verified.

• lab_grown_grading_landscapeWho grades Lab Grown Diamonds todayread-only

  The current state of who grades Lab Grown Diamonds and how: GIA, IGI, HRD Antwerp, and the FTC position. Every item carries a source and a date.

• lab_grown_price_indexLatest tracked Lab Grown Diamond retail price readingread-only

  The latest tracked retail price reading for Lab Grown Diamonds, with source and date. Market context for shoppers, not investment guidance.

• search_encyclopediaKeyword search across the diamond encyclopediaread-only

  Keyword search across the 90 entry diamond and gemology encyclopedia. Ranks case insensitive keyword hits by field, weighting the term above the definition above the body. Returns the best matches as term, category, and a definition snippet. Use define to fetch a full entry.

• search_inventorySearch Stienhardt's live inventoryread-only

  Search Stienhardt's public Shopify catalog of engagement ring settings and fine jewelry (New York, direct). Loose-diamond stock cannot be verified here; those searches return public catalog listings flagged availability_verified false plus a storefront browsing link. Returns public catalog prices, selected variants, and links; availability is verified for jewelry only and is not a reservation. Use for questions like 'show me platinum wedding bands' or 'show me tennis bracelets'. Not for appraisal or price advice on stones sold elsewhere.

• verify_diamond_reportWhere and how to verify a diamond grading reportread-only

  Returns the official verification URL and a three step checklist for confirming a diamond grading report with the lab that issued it. Supports GIA, IGI, and GCAL. This tool never verifies anything itself. It tells you where and how.
