🌌 Rare green-black Rainbow Amethyst Cutbase – 6.5 cm · 150 g · Uruguay ✨

A truly unique piece from the depths of Uruguay: this Rainbow Amethyst cutbase showcases an extraordinary combination of greenish-black crystals , delicate purple banding , and a rare double crystallization . Measuring 6.5 cm tall and weighing 150 g, it is a powerful collector's item of mesmerizing beauty.

🌿⚫ Unique color & structure

The mysterious green-black hue is created by fine inclusions of hematite or chlorite during the growth process. These minerals give the crystals their dark, mystical depth and make them shine in contrast to the violet amethyst. The purple banding , the fine color zones within the crystal, is typical of amethyst and is caused by changing conditions during crystallization.

💎 Double crystallization & “sugary” surface

This piece exhibits a rare double crystallization —meaning that tiny crystals have grown on top of an existing crystal layer. This second generation of crystals forms the so-called "sugary" surface : a fine-grained, glittering structure that looks as if the amethyst has been dusted with sugar.

Such a fine double formation is extremely rare and is highly valued by collectors because it only occurs under very specific geological conditions.

🌈 Rarity & Value

The combination of green-black coloring , violet banding , and double crystallization makes this piece a true rarity. Such amethysts are among the most sought-after forms of the rainbow amethyst varieties —they are not only aesthetically valuable but also highly valued for their energetic properties.

💫 Effect

Rainbow Amethyst is considered a crystal of transformation and inner harmony . This special green-black variety combines the clarifying energy of amethyst with the protective and grounding power of dark minerals. It is said to:

🌌 give inner balance and spiritual clarity,

🌿 Promote healing and protection,

🕊 and gently bring the soul into harmony.

🎁 A mystical gift of nature

The fascinating formation of crystals

The formation of crystals is a fascinating process that takes place deep within the Earth over millions of years. It begins with a highly concentrated solution of minerals in rocks or liquids. Under specific conditions such as high pressure and high temperature, these minerals react and arrange themselves, forming the first crystal nuclei. Gradually, other molecules attach themselves to these nuclei, forming a crystal lattice. The composition of the minerals, the cooling rate, and environmental factors influence the size, shape, and clarity of the crystals.


During this slow crystallization, breathtaking shapes and colors emerge, giving the crystals their characteristic beauty. Rock crystals, amethysts, and rose quartz (to name a few) are the result of this impressive natural creation process. Each crystal is a unique work of art from nature, bearing the history and conditions of its formation within itself. The variety of colors and structures reflects the various geological processes that have taken place over millions of years, making each crystal a fascinating testament to the natural world.
