Tools

browse_collection Browses the web · ~407 tokens
Browse one collection/category page deterministically — the same product set, ordering, and filters a shopper sees on the site. Pass the collection permalink from list_collections (e.g. 'wedding-rings/womens/eternity'). Filter by style tags, metals, or sort; paginate 24 per page. Prefer search_produ
get_product ~295 tokens
Full detail for one product: metal variants with live starting prices, the complete customization matrix (ring sizes, widths, thickness, color, finish, stone type, engraving rules) with the ids to echo into price_product, stone specifications, physical dimensions, size-group siblings, matching piece
get_product_images ~210 tokens
Every gallery image for a product with high-resolution URLs. Each image lists only renditions that actually exist, largest first — modern photography is 2048x2048 WebP at the 'original' size — plus the metal tone, band width, and finish the photo shows, and descriptive alt text. Identify the product

25karats brand facts and policies for answering shoppers: who we are, shipping and production times, returns, warranty, resizing, engraving, financing, and contact details. Call this before answering policy questions rather than guessing.

The navigable catalog taxonomy: every public collection with its permalink (for browse_collection), title, and product count, as a tree. Call once to orient; results change rarely.
price_product ~1044 tokens
Exact live price in USD for a fully configured item — the same number the customer pays on 25karats.com (computed from current metal market pricing, not a cached feed price). Identify the item by variant_id (from get_product) or style_code, optionally with metal. For wedding bands pass ring_size/wid

Search 25karats' in-stock IGI/GIA-certified lab-grown loose diamonds (center stones for engagement rings) by shape, carat, color, clarity, cut, and price. Prices are the live customer price in USD. Each stone includes certificate details, measurements, and image/video links when available. A chosen
search_products ~588 tokens
Search the 25karats made-to-order catalog (wedding bands, engagement rings, his & hers sets, fine jewelry) by keywords or a style code.
