Amethyst Cave – Twin Cathedrals of Monumental Beauty

This amethyst cave is unlike anything found in typical retail offerings in the Aussie crystal market. If you're looking for giant crystals for sale, this pair towers above most people at nearly two meters high, and weighs a massive 318kg (combined weight of the pair). They're not just stunning display pieces, they are geological monuments. 

The deep interior reveals glittering violet crystal points, displayed in two polished halves. This is not simply a sculpture — it’s a giant amethyst geode that once existed as a single colossal formation, now revealed in near perfect symmetry.

Giant Amethyst Geode – Delivered Exactly As Shown

This listing is for the exact large amethyst geode shown (you will receive both halves). Each half of the original geode has been cleanly cut and polished along the front face to reveal the breathtaking crystal formations within. The rest of the structure remains untouched — just as it was discovered in Brazil.

The size, depth, and richness of this amethyst cave pair is impossible to miss. Each half can be displayed on either side of a feature space — framing a fireplace, doorway, console, or gallery wall to create a symmetrical and commanding presence. Some collectors place them facing outward as matching guardians; others position them with the crystal sides angled inward to recreate the sense of a complete geode cave.

As the largest amethyst cathedral we currently have available, this matched pair isn't just for show — it’s a structural element, a centrepiece, and a geological landmark all in one. It is a true one-of-a-kind treasure, chosen for its scale, natural beauty, and the unmatched presence it brings to any space.

This giant amethyst geode was sourced directly from Brazil, known worldwide for producing amethyst of exceptional depth and quality. Weighing a combined 318kg, this matched pair has been classified A Grade and selected specifically for its completeness and natural symmetry.

Featuring two halves split from a single enormous formation, this large amethyst geode stands as a testament to the Earth’s raw geological artistry. The polished faces of each half reveal tightly packed violet points, catching the light from every direction. This is one of very few matched pairs of this size to be made available outside of institutional collections.

Crystal Peak Treasures proudly offers only authentic, natural pieces. This set reflects the highest quality Brazilian mineral exports — selected not just for visual impact, but for lasting collector value.

Large Amethyst Geode - A Matched Pair of Cathedrals for Serious Collectors

This set isn’t for casual buyers — it’s for those seeking serious giant crystals for sale that go beyond size alone. This matched pair of cathedrals carries not just scale, but significance — a geological treasure formed as one, split to reveal its natural architecture, and now preserved for display. It is a centrepiece worthy of the most refined private collection or high-impact interior.

Collectors often place matched geodes like these on either side of entryways, fireplaces, altars, or gallery walls — creating a sense of balance and intention. When displayed this way, the pair doesn’t just fill a room — it reshapes it. The shimmering points within each face catch light from different angles throughout the day, offering an ever-changing display that feels alive and elemental.

Sold together as two halves of a split geode, this is the largest amethyst cathedral that we have in stock, and quite possibly the largest available on the Australian market. The pair carries a level of presence, authenticity, and visual power that few pieces can match. This matched set offers not just scale, but significance — a centrepiece worthy of the most refined private collection or high-impact interior.

Amethyst Cave – A Natural Masterpiece Revealed

Amethyst cave specimens of this magnitude are rarely seen outside of museum displays. This matched pair, split from a single formation, captures the untouched structure and natural balance of an earth-born cathedral. The crystals are densely packed and saturated with deep violet, polished just enough to reveal their inner brilliance without losing their raw integrity.

The presence of this giant amethyst geode is undeniable. Displayed as open halves or flanking a feature space, the pair brings a grounded, elemental energy to its surroundings. It's not only an object of beauty — it's a geological statement unlike anything else in the Australian crystal market.
