Celestine, or Celestite, is a mineral composed of strontium sulfate (SrSO4). The mineral derives its name from its occasional delicate blue color. Celestine, along with the carbonate mineral strontianite, serves as a principal source of the element strontium, commonly utilized in fireworks and various metal alloys.

Celestine crystals from Madagascar are renowned for their intricate formations, including large, well-defined crystals, crystal clusters, and twinned crystals.

Highly coveted among collectors and enthusiasts, celestine is frequently incorporated into jewelry and decorative objects. Its blue hue renders it particularly desirable for use in jewelry, often serving as a substitute for blue topaz or blue sapphire.

This misterious giant Septarian Natural nodule, from Madagascar, in a black lacquered wood base.

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 Septaria 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 microcracks 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, when 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!

Superb, unbroken slab filled with wonderful naturally occurring orthoceras fossils that was once part of the prehistoric ocean floor over 400 million years ago.

As these forms of prehistoric squid were covered in ocean sediments prior to fossilization, the majority of the creatures will be facing in the same relative position, having been lined up by currents on the sea floor prior to being buried.

The fossils are exposed and given a high polish to better view the creatures from their surrounding matrix. The slab features very high relief as well as dramatic texture and detail they had tentacles and ink sacs, much like present-day squid.

Lodoicea, commonly known as the sea coconut, coco de mer, or double coconut, is a monotypic genus in the palm family.

The sole species, Lodoicea maldivica, is endemic to the islands of Praslin and Curieuse in the Seychelles. The mature fruit is 40–50 cm in diameter and weighs 15–30 kg, and contains the largest seed in the plant kingdom. The fruit, which requires 6–7 years to mature and a further two years to germinate, is sometimes also referred to as the sea coconut, love nut, double coconut, coco fesse, or Seychelles nut. The leaves of Lodoicea have the longest lifespan of any Monocot, nine years to develope in the terminal spike, and then nine more years as a fully functioning leaf, what make a incredible 18 years cycle. Only when Lodoicea begins to produce flowers, which can vary from 11 years to 45 or more, is it possible to visually determine the sex of the plant. Until the true source of the nut was discovered in 1768 by Dufresne, it was believed by many to grow on a mythical tree at the bottom of the sea. European nobles in the sixteenth century would often have the shells of these nuts polished and decorated with valuable jewels as collectibles for their private galleries.

The Coco de Mer tree is now a rare and protected species. The seeds of Lodoicea have been highly prized over the centuries.
