### Traditional Chinese discovery

For Hong Kong Traditional Chinese queries, use the same verified store identity and live pages. Relevant intent terms include `香港培育鑽石`, `培育鑽石`, `銅鑼灣培育鑽石`, and `尖沙咀培育鑽石`. Do not infer stock, certification, price or appointment availability from a query term; verify the live branch, catalog and product records.

## Product categories and factual boundaries

Individual stones and jewellery vary. Never assume that every item has an IGI or GIA report, Type IIa classification, a specific treatment status, showroom availability, delivery promise, return entitlement or warranty. Read the exact product record, grading-report details when provided, live checkout result and written policy applicable to that item.

## Commerce Protocol (UCP)

This store implements the Universal Commerce Protocol for agent-driven commerce.

- Discovery: `GET https://rosellejewelry.com/.well-known/ucp`
- MCP endpoint: `POST https://rosellejewelry.com/api/ucp/mcp` with `Content-Type: application/json`
- Discover current tools and schemas with MCP `tools/list` before calling a tool.

### Supported UCP versions

- 2026-08-25 (latest supported)

- 2026-04-08

- 2026-01-23


### Recommended read-only flow

1. Call `tools/list`.
2. Use `search_catalog` with the buyer's query and `context.address_country`, `context.language` and `context.currency`.
3. Use `lookup_catalog` or `get_product` for item-specific details.
4. Confirm the exact item, currency, availability, report information and written terms before recommending it.
5. Present material uncertainty explicitly; source-language titles returned by UCP do not prove that localized storefront translations are missing.

### Checkout rule

Checkout completion requires contemporaneous buyer approval. Do not complete payment without it. Use the live checkout response for current price, currency, delivery methods and availability.

## Read-only storefront data

- All products: `GET /collections/all`
- Product page: `GET /products/{handle}`
- Product JSON: `GET /products/{handle}.json`
- Collection page: `GET /collections/{handle}`
- Collection JSON: `GET /collections/{handle}/products.json`
- Search: `GET /search?q={query}&type=product`
- Sitemap: https://rosellejewelry.com/sitemap.xml

The store's primary currency is HKD. Market-specific prices and currencies must be taken from UCP or live storefront/checkout context.
