Milligram-Level Precision for Diamonds, Jewelry, and Fine Materials

The Superior Balance® I-Diamond Digital Scale is designed for highly detailed weighing applications that require exceptional accuracy. Featuring a 20-gram maximum capacity with 0.001-gram readability, this precision scale is ideal for diamonds, gemstones, precious metals, jewelry components, coins, collectibles, laboratory-style samples, and other small lawful items.

Its compact tabletop design provides a stable weighing surface without requiring excessive workspace. A clear digital display, tare function, and calibration capability make the I-Diamond a practical choice for jewelry counters, hobby workspaces, collecting, and professional precision weighing.

Benefits of Use

The Superior Balance® I-Diamond measures in precise 0.001-gram increments, allowing users to detect extremely small differences in weight. This milligram-level readability is especially useful for diamonds, gemstones, fine jewelry components, and other lightweight items that require more detailed measurements than standard pocket scales can provide.

The 20-gram capacity is well suited for small, high-value items and precision materials. Its compact size makes it easy to position on a jewelry counter, desk, workbench, or dedicated weighing station.

The tare function allows the weight of a lightweight tray or container to be subtracted from the displayed measurement. This makes it easy to measure only the contents placed inside.

Calibration capability helps maintain dependable performance and accurate readings over time.

Capacity and Precision

The I-Diamond provides a maximum weighing capacity of 20 grams and displays measurements in precise 0.001-gram increments.

This combination of capacity and readability makes the scale suitable for weighing:

• Diamonds and gemstones
• Gold, silver, and other precious metals
• Jewelry and small components
• Coins and collectibles
• Craft and hobby materials
• Laboratory-style samples
• Other small lawful items requiring milligram-level precision

How to Use

Place the scale on a flat, stable, and level surface away from vibration, strong airflow, moisture, and static electricity.

Turn the scale on and allow the digital display to return to zero. Place the item directly on the weighing platform, or position a lightweight tray or container on the platform.

Press the tare button to subtract the container’s weight, then add the item or material being measured. Wait for the displayed reading to stabilize before recording the result.

Calibrate the scale periodically using the correct calibration weight and the manufacturer’s instructions. Because the I-Diamond reads to 0.001 gram, even slight movement, air currents, temperature changes, or an uneven surface may affect the measurement.
