What it is Filled

A mineral, rock or organic material cut and polished for jewellery or ornament, valued for beauty, durability and rarity, such as diamond, sapphire, ruby, emerald and opal; synthetic and treated stones are common.

Why it exists Filled

Let an agent handle gemstones by identity, properties, treatments, grading, ethical sourcing and valuation, recommending laboratory reports.

Distinguishing features Filled

  • Valued for beauty and durability
  • Natural, synthetic or treated
  • Graded by laboratories
  • Ethical sourcing concerns

What robots and AI may and may not do Filled

Must not

  • Sell or describe a treated, synthetic or imitation stone as natural and untreated.
  • Help move gemstones in breach of sanctions or certification schemes for conflict stones.
  • Invent grading reports, weights or origin claims.
  • Disclose who holds valuable stones and where they are kept.

Only with a human decision

  • Valuing a gemstone for sale, insurance or inheritance.
  • Buying or selling a stone on someone's behalf.

May

  • Describe a gemstone's species, treatments and grading from a recognised laboratory report.
  • Record the provenance and certificates of stones held by an owner.

Moral aspects Filled

  • Gem mining has funded armed conflict and relies on dangerous, poorly paid work.
  • Gemstone sales depend on trust; misdescription transfers loss to buyers.

Who is affected

  • Miners and mining communities
  • Buyers and owners
  • Honest traders

Owners Filled

Steward

The owner of the stone; gemmological laboratories issue reports but do not own it.

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.gemstone
  • Wikidata: Q83437 (https://www.wikidata.org/wiki/Q83437)

Direct properties required Filled

  • Stone mass: metric carat - Mass is measured with a calibrated gemstone balance, with one metric carat equal to 200 milligrams.
  • External dimensions: millimetres - Length, width and depth are measured with suitable gauges or optical instruments without damaging the stone.
  • Scratch hardness: Mohs scale - Hardness depends on mineral identity and is assessed by comparative scratch resistance, although scratching can damage a finished gemstone.
  • Refractive index: dimensionless - Refractive index is measured with suitable gemological equipment where transparency, surface geometry and instrument limits permit.

Recognition required Filled

  • Cut, colour, clarity and carat
  • Laboratory report numbers
  • Imitations such as glass look similar
  • Cut and polished coloured or colourless stones in settings.

Capabilities and actions required Filled

  • identify gem species and varieties
  • understand treatments and synthetics
  • read laboratory reports
  • check ethical sourcing

Hazards and failure modes required Filled

  • Undisclosed treatments or synthetics
  • Conflict-sourced stones
  • Agents giving investment advice

Standards and interfaces required Filled

  • Kimberley Process Certification Scheme
  • CIBJO Blue Book nomenclature
  • Consumer protection on disclosure of treatments

Context of use required Filled

  • Jewellery, ornament, investment and heritage objects.
  • diamonds
  • corundum (ruby and sapphire)
  • beryl (emerald and aquamarine)
  • organic gems such as pearl and amber
  • engraved and seal stones (historical)

Sources Filled

  1. Wikidata item Q83437: gemstone - identity and sense of the item
  2. Wikipedia: Gemstone - general description of the item

Open questions

  • Should gem species be separate entries?
  • How should laboratory reports be linked?
  • How should historical seal stones be linked?
