This beautiful polished septarian egg, from Madagascar, shows its interior crystallization in contrast with exterior colors, in a brass stand.

Septarias are prehistoric marine nodules of bio sedimentary origin followed by dehydration during diagenesis, which today are found as large pebbles in clay soil. The creation of a Septarian is a succession of events along millions years, they form around a core of organic matter (plant or animal).

Sediments continue to settle on the nodule, compacting it under their weight which will flatten it and expel water, while inside micro-cracks begin to form, amplified by tectonic movements. It is in these shrinkage slots that over time dissolved minerals will crystallize.

Its name comes from the Latin "septum" which means partition, barrier, indeed, the polishing of the nodule reveals and sublimates its elegant marbling of black calcite, millions of years that offer these sumptuous minerals, each piece is unique!

Microcline is an important igneous rock-forming tectosilicate mineral. It is a potassium-rich alkali feldspar. It is common in granite and pegmatites. Microcline forms during slow cooling of orthoclase. Microcline may be clear, white, pale-yellow, brick-red, or green; it is generally characterized by cross-hatch twinning that forms as a result of the transformation of monoclinic orthoclase into triclinic microcline.

Bismuth Cathedral crystals that truly command attention. Bismuth, a fragile yet crystalline material, finds itself within the realm of semi-precious semi-metals, naturally adopting captivating geometric forms that are utterly distinctive. Infused with refractive properties, it dazzles with an opulent, iridescent sheen reminiscent of an enchanting oil-slick spectrum. Historically sourced as a by-product from the depths of copper, lead, and tin mines, it once confounded ancient observers, often being mistaken for lead or tin due to its beguiling appearance.

When ignited in the presence of oxygen, bismuth dances with a sapphire-blue flame, releasing ethereal yellow fumes as its oxide is formed—an intriguing testament to its chemical nature. As rare as precious silver and possessing the heftiness akin to lead, a cubic foot of bismuth would staggeringly weigh over 600 pounds, attesting to its density.

These extraordinary Bismuth crystals, nurtured within laboratory environments in the United Kingdom, emerge as a rarity, as their naturally occurring counterparts remain elusive treasures. Their unique kaleidoscope of hues and mesmerizing contours positions them as sought-after ornamental pieces, gracing spaces with unparalleled allure. Beyond their aesthetic significance, these crystals also find pragmatic roles in medicines, cosmetics, inks, paints, and even fire sprinkler systems—a testament to their versatile utility.
