Heavy duty 500kg Crane Scale

Best for Jewelry: Look for scales with a readability of 0.01 gram (g) or 10 milligrams (mg). This precision is suitable for weighing most gold, silver, and average-sized gemstones.

Professional/Diamond Use: For weighing tiny diamonds or very high-value items, you might need a scale with 0.001 gram (mg) readability, often called a milligram scale.⁴

Common Capacities: The most common pocket sizes are 200g, 500g, or 1000g (1kg).

• A 500g / 0.01g scale is a great, versatile choice, offering high precision while still handling multiple rings or small batches of material.⁶

   

Gram (g): Standard unit.

Carat (ct): Essential for gemstones ($text{1 carat} = 0.2text{ grams}$).

Troy Ounce (ozt):⁹ Used for precious metals like gold and silver.¹⁰

Pennyweight (dwt):¹¹ Used in the dental and jewelry industries.

Tare Function: Allows you to place a small tray or container on the scale and “zero out” its weight, so you only measure the weight of the items placed inside.¹²

Calibration: High-precision scales require periodic calibration to maintain accuracy.¹³ Many models come with a small calibration weight (e.g., ¹⁴$50text{g}$ or ¹⁵$100text{g}$) and a simple calibration button.¹⁶

Protective Cover: The scale usually includes a flip-top lid that protects the delicate weighing platform and sensors when carried in a pocket or bag.¹⁷
