Cherished for its exquisite craftsmanship, vibrant colors and healing properties, amethyst is a bountiful type of quartz. Although all amethyst gemstones are valuable, jewelers and collectors regard deep purple amethyst more highly than other shades of amethyst. Egyptian and British royalty wore purple amethyst jewels centuries ago. Like all gemstones, purple amethyst crystals accumulate grime and oil, which dull their radiance. Regularly cleaning purple amethyst restores its vibrant beauty and luster. Carefully clean purple amethyst rocks using mild solutions.

Fill a clean bowl with 1 qt. hot water. Stir 1 tbsp. mild dishwashing liquid into the hot water.

Submerge the purple amethyst rock in the solution. Let the amethyst soak in the solution for 15 minutes to allow the mild soap to dissolve grime from the rock’s surface.

Scrub the entire rock gently with a soft bristle brush, such as a clean toothbrush. Remove all grime residue and oil from the rock.

Rinse the amethyst rock thoroughly with distilled water. Unlike tap water, distilled water ensures no mineral deposits develop on the rock's surface after rinsing it.

Wipe the amethyst gently with a microfiber cloth or towel to absorb moisture.

Place the amethyst on a fresh microfiber cloth or towel to air-dry completely.

Store the clean amethyst separately in a box lined with soft fabric for preservation.
