birthstone_for_month

compare_gems
Compare two gems
Side-by-side physical properties of two gem species with a plain verdict on which is harder, and a note on toughness — the half of durability the hardness scale does not show. Good for "sapphire or diamond for an everyday ring".

define_gem_term
Define a gemmological term
Look up a gemmological term in The Gem Lexicon of Ministry of Gems — 215 definitions verified by an FGAA-qualified gemmologist. Returns the definition, its subject section, and a citable anchor URL. Use for terms such as padparadscha, corundum, parti sapphire, unheated, or asterism.

faceup_size_estimate
Face-up size for any gem species
Approximate face-up millimetre dimensions for a stone of a given species, shape and carat weight — and, unlike diamond-only calculators, corrected for specific gravity, so a 2 ct sapphire, spinel, emerald or opal is sized correctly rather than as if it were diamond. Shapes: round, oval, cushion, emerald, pear, marquise, princess, radiant, heart, trillion.

gem_care_guide
How to clean and wear a gem
Whether warm soapy water, an ultrasonic cleaner or a steam cleaner is safe for a given gemstone, plus everyday-wear notes, from the FGAA-reviewed care table. Covers sapphire and ruby, diamond, emerald, opal, pearl, tanzanite, tourmaline and more.

gem_properties
Gem physical properties
Mohs hardness, refractive index, specific gravity, birefringence and crystal system for a gem species (diamond, corundum/sapphire/ruby, emerald, spinel, opal, tourmaline, garnet, quartz and more), from the FGAA-reviewed Gem Data Tables. Accepts trade names — "sapphire" resolves to corundum, "tsavorite" to garnet.

lab_report_check
Where to verify a laboratory report
The issuing laboratory's own verification page and a four-step checklist for confirming a gemstone or diamond grading report — GIA, IGI, GRS, SSEF, Gübelin, AGL, Lotus, GIT, HRD, GCAL and others, including the coloured-stone laboratories diamond tools omit. Explains what "FGAA" means and flags unrecognised lab names. Routes to the lab; does not verify the report itself.

sapphire_price_guide
Sapphire price per carat (AUD)
What natural sapphires actually cost per carat in Australian dollars, from Ministry of Gems' published price guide: bands by origin (Australian, Ceylon) and size, with the stone count behind each band and the date the bands were computed. Answers "how much is a 2 carat sapphire" honestly, as a house guide rather than a market index.

verify_gem_passport
Verify a Digital Gemstone Passport
Cryptographically verify a Ministry of Gems Digital Gemstone Passport by stone ID. Recomputes the SHA-256 digest of the signed record and checks its Ed25519 (EdDSA) signature against the house public key, then returns the attested record: species, carat, dimensions, cut, colour, clarity, origin, treatment and certificate status. Use when a buyer asks whether a stone or its passport is genuine, or before quoting any fact about a specific Ministry of Gems stone.
