✨ Extra Large Brazilian Amethyst Cathedral Geode with Calcite – 17.30kg | 18"
🌙 X Large Brazilian Amethyst Cathedral with Calcite – Spectacular 17.30kg One-Off Geode
This spectacular X Large Brazilian Amethyst Cathedral Geode is an impressive one-off natural crystal, standing approximately 18 inches / 45.7cm high, around 9 inches / 22.9cm across and approximately 8 inches / 20.3cm deep at the widest point.
Weighing an incredible 17.30kg, the Cathedral is filled with beautiful purple Amethyst crystal points, surrounded by natural agate and chalcedony edging and contrasting darker outer matrix.
Several natural Calcite deposits and secondary mineral formations have developed amongst the Amethyst, including striking white Calcite clusters together with distinctive rhombohedral and scalenohedral formations, the latter often known as Dog Tooth Calcite.
Amethyst is known for its beautiful purple colouring, from softer lavender tones through to rich deep violet, with every natural geode forming its own individual crystal points, colour variations and mineral features.
Amethyst is traditionally chosen for calm, protection, emotional balance, intuition and spiritual awareness, making a Cathedral of this size especially beautiful for a living area, healing room, meditation space or peaceful sanctuary.
This is a truly exceptional one-off Brazilian Amethyst Cathedral for collectors, crystal lovers and anyone looking for a spectacular natural centrepiece with incredible mineral detail.
✨ Why You'll Love This X Large Amethyst Cathedral
This really is a show-stopping Amethyst Cathedral, with layer after layer of natural crystal detail and one particularly spectacular feature hidden deep within its base.
The tall Cathedral opens into a glittering interior of purple Amethyst points, with softer lavender crystal around the outer areas gradually giving way to richer, deeper purple as your eye moves further inside. The polished agate and chalcedony edging beautifully traces the natural shape of the geode, while the dark outer matrix gives a striking contrast to all that purple sparkle.
Scattered amongst the Amethyst are fascinating natural Calcite formations, including bright white clusters and distinctive rhombohedral and Dog Tooth Calcite crystals nestled within the quartz matrix. These secondary minerals make the Cathedral even more interesting to explore and give this exact specimen its own completely individual character.
But one of its most incredible features is right down at the base. Peer into the lower part of the Cathedral and a deep natural cavern opens beneath the surrounding crystal points, filled with some of the deepest purple Amethyst in the whole piece. From the front it feels almost hidden, drawing you in to look further inside, while a side/rear view reveals just how large and deep that natural cave actually is.
At 17.30kg, this is a substantial piece of natural crystal that will instantly draw the eye, but it is the combination of deep purple sparkle, dramatic cavern formation, contrasting Calcite and beautiful natural geode structure that makes it so special.
This is one of those Amethyst Cathedrals you could look into again and again and still find something new — a spectacular one-off crystal cave full of colour, depth, sparkle and fascinating natural mineral formations.
