Materials¶

The Metals module tracks your raw metals — gold, silver, platinum, palladium, and other metals. It manages inventory levels, market prices, and how metals are used in your products.

Gem Logic comes with pre-defined metals for common alloys (9kt, 14kt, 18kt, 22kt, 24kt gold, silver, platinum, and palladium variants), each with their purity coefficient.

Creating a metal¶

Navigate to Stock ‣ Metals and click Create metal. Fill in:

Name: Metal name (e.g., “18kt yellow gold”)
Type: Metal or gemstone
Price: Your price per weight unit
Currency and Weight unit: How the metal is measured (gram, carat, troy ounce, etc.)
Profit margin: Percentage used when calculating buying prices
Sync with market: Automatically update the price from live market data

Metal detail page¶

The detail page has three tabs:

Details: Current inventory levels, metal edit form, and a market price chart for base metals showing price history.
Inventory movements: A log of all stock changes — every addition, deduction, sale, purchase, and conversion is recorded with quantity, type, and date.
Products: Products that use this metal in their cost breakdown.

Inventory management¶

Each metal tracks its total stock weight. Inventory can change through several actions:

Adding stock: Click Add inventory on the detail page to manually add metal.
Stock in: Receive metals from a supplier via stock in.
Product consumption: When Manage metal stock is enabled on a product’s cost line, metal is automatically deducted when product stock increases.
Order usage: Metals used in repairs, creations, and sales are tracked and deducted.

Client metal deposits¶

Customers can deposit their own metal (e.g., old gold for a custom creation). Deposited metal is tracked separately per client. From an order, you can:

Use client metal: Deduct from the client’s deposited inventory, with an optional loss percentage.
Return client metal: Return unused metal back to the client.

Sending and converting metals¶

Use the Send action on an inventory record to:

Send metal to a contact (e.g., an external workshop)
Convert between alloys (e.g., melt 18kt gold into 14kt gold) — the system uses purity coefficients to calculate the correct output weight
Apply a loss percentage to account for metal loss during processing

Market price sync¶

Gem Logic fetches live market prices for gold, silver, platinum, and palladium. When Sync with market is enabled on a metal, its price updates automatically. Alloy prices are calculated from the pure metal price using their purity coefficient.

Price linking¶

Non-base metals can link their price to another metal with a percentage adjustment. This is useful for custom alloys that should follow a base metal’s price.
