• A beautiful and striking one-of-a-kind collector’s specimen

This large and impressive flower-like Flower Amethyst is a dark-toned amethyst quartz formation, with occasional violet nuances typical of amethyst. Hundreds of small quartz crystals form fan-like and petal-like groups, giving the stone an almost floral structure. Its form reflects unusual crystallisation conditions, in which small quartz crystals grew in dense, radiating groups to create a nearly petal-like whole.

The overall colour of the piece is very dark, almost blackish grey. Its surface reveals both glassy crystal faces and paler, more translucent areas of quartz. The tones shift depending on the light: in dim light the stone appears almost black, while in bright light individual crystals reveal violet and smoky shades. Among the quartz crystals, and sometimes glowing through them, are mossy green tones associated with the celadonite present in the stone.

Origin of the amethyst cluster – Ametista do Sul

Ametista do Sul is located in the state of Rio Grande do Sul in southern Brazil and is known worldwide for its large amethyst geodes. The amethysts of this region formed in basalt cavities of the Serra Geral Formation, where minerals crystallised in layers: greenish celadonite, chalcedony/agate, clear quartz and finally violet amethyst. For this reason, amethysts from Ametista do Sul may show not only purple amethyst, but also green, grey, clear and smoky tones. Geodes can develop over millions of years as mineral-rich hot water fills cavities formed within the basalt.

Celadonite

The green mineral visible in the cluster is celadonite. Celadonite is a green potassium- and iron-bearing phyllosilicate, a mineral belonging to the mica group, which often forms in cracks and cavities of volcanic rocks such as basalt as a result of hydrothermal processes. In the amethyst geodes of Ametista do Sul, the green celadonite layer occurs on the walls of the geode before the crystallisation of clear quartz and amethyst. Its presence both in the host rock and as a green tone glowing through the quartz therefore fits well with the geology of the region.

Historically, celadonite is also known as a natural green pigment. The green earth or terre verte pigment, based on celadonite and glauconite, has been used in art since antiquity, including in frescoes, icon painting and early European painting.

Symbolic meaning

In crystal tradition, amethyst is regarded as an exceptionally powerful and protective stone, and is believed to carry a high spiritual vibration. It is traditionally thought to transform negative energies into love. Its calm presence is associated with higher states of consciousness. In meditation, amethyst is believed to draw the mind away from everyday concerns and towards tranquillity, harmony, deeper understanding and other dimensions. It is considered one of the most spiritual stones. Amethyst is associated with the crown chakra and is also traditionally linked with Pisces.

The green colour of celadonite, in turn, has been associated with the cycles of nature, renewal, balance and vitality.

Please note: Symbolic meanings associated with stones are based on cultural traditions and personal experience. Each person may experience the same mineral in a different way, and its effects have not been demonstrated by scientific research. As crystals are natural products, every specimen is unique in its structure, colour and crystallisation.
