Can You Tumble Turquoise? A Guide to Polishing and Protecting This Precious Stone

Turquoise, with its captivating blue-green hues and unique veining patterns, is a gemstone cherished for its beauty and historical significance. But can you tumble turquoise, and if so, how? This question arises frequently among lapidary enthusiasts and jewelry makers, as tumbling is a popular method for polishing gemstones.

The answer, unfortunately, is not straightforward. While tumbling can be a viable option for certain types of turquoise, it can also pose risks to this delicate stone. Understanding the intricacies of turquoise and its varying characteristics is essential before attempting any tumbling process.

The Delicate Nature of Turquoise

Turquoise is a relatively soft gemstone, ranking 5 to 6 on the Mohs Hardness Scale. This means it's susceptible to scratches and abrasion. Additionally, its porous nature makes it prone to absorbing moisture, oils, and other substances, which can negatively impact its color and vibrancy.

Factors to Consider Before Tumbling Turquoise

1. Type of Turquoise:

  • Stabilized Turquoise: This type of turquoise undergoes a treatment process to enhance its durability and stability. Stabilized turquoise is more resistant to moisture and can withstand the tumbling process.
  • Unstabilized Turquoise: This type of turquoise remains in its natural state and is more sensitive to damage. Tumbling unstabilized turquoise is generally not recommended.

2. Tumbling Method:

  • Barrel Tumbling: This traditional method involves placing gemstones in a rotating barrel filled with abrasive grit and water. While effective for hard stones, the friction and pressure of barrel tumbling can be too aggressive for turquoise.
  • Vibratory Tumbling: This gentler method utilizes vibrations to polish gemstones. It's a safer option for softer stones, including turquoise, as it reduces the risk of chipping or cracking.

3. Grit Size and Duration:

  • Coarse Grit: Using coarse grit can damage turquoise, leaving scratches and dulling its surface.
  • Fine Grit: Fine grit is ideal for polishing turquoise without causing harm.
  • Duration: Short tumbling durations are essential to minimize the risk of wear and tear.

4. Water Quality:

  • Clean Water: Using clean, fresh water is crucial for tumbling turquoise. Impurities in the water can stain or damage the stone.

Tumbling Turquoise: A Careful Approach

If you decide to tumble turquoise, exercise extreme caution. Here's a safe approach:

1. Stabilized Turquoise Only: Opt for stabilized turquoise, which is more durable and can withstand the tumbling process.

2. Vibratory Tumbling: Use a vibratory tumbler instead of a barrel tumbler, as it offers a gentler polishing action.

3. Fine Grit and Short Duration: Start with a fine grit and shorten the tumbling time to minimize the risk of damage.

4. Monitor Regularly: Monitor the turquoise throughout the tumbling process. Remove any stones showing signs of wear or damage.

Alternatives to Tumbling Turquoise

If you're concerned about the potential risks of tumbling turquoise, consider these alternative polishing methods:

1. Hand Polishing: Use polishing cloths, felt pads, and fine-grit sandpaper to polish turquoise by hand. This method offers greater control and allows you to avoid excessive pressure.

2. Buffing: A buffing wheel can be used to polish turquoise to a high shine. However, it requires experience and care to avoid damaging the stone.

3. Professional Polishing: Seek a professional lapidary to polish your turquoise. They have the experience and specialized equipment to ensure a safe and effective polishing process.


Can you tumble turquoise? The answer is yes, but with caution. Tumbling can be a viable option for stabilized turquoise if you use a vibratory tumbler, fine grit, and short tumbling durations. However, it's essential to be mindful of the delicate nature of turquoise and avoid any methods that could damage its beauty. If you're uncertain, consider alternative polishing methods or seek professional assistance to ensure the safety and preservation of your treasured turquoise.
