Fossilised Wood with Blue-Green Highlights
Located in London, GB
This striking fossilised wood cross-section, dating to the Miocene epoch (23-5 million years ago) and featuring paint-like streaks of greens, blues and browns, is a beautiful natural history specimen and impactful display piece. This is a magnificent example of the results of permineralisation, a process through which buried wood tissue, permeated by minerals transported in water, can transform into vibrant fossils. This particular example has fossilised over a copper deposit, resulting in the bright inclusions of copper minerals that manifest as impressive streaks of blue, green and red. This distinctive colouration is unique to Colla wood...

Seafoam Green Fluorite Crystal Mineral Specimen – Dongpo Ore Field, China
Located in Edison, NJ
This is an attractive example from the Dongpo Ore Field of China. The best Dongpo fluorites are known for translucent crystals with great form and an attractive light green tone. This is a prime example featuring three sharp, cuboctahedral crystals in a saturated, seafoam green tone. The fluorites have multi-stepped faces along their sides and central faces that are smooth, acting like windows into the translucent crystals. The crystals’ lustrous sheen further highlights their intricate structure. They have formed atop a contrasting matrix (host-rock) of bladed, beige dolomite crystals. The dolomite is sharp and has formed in dense intergrown rosettes. Peeking out from under the dolomite and fluorites is a shimmering matrix of druzy, white quartz that frames the piece overall. The juxtaposition of textures, colors, and species makes the already colorful fluorite crystals...

Large Polished Labradorite Freeform
Located in Wormelow, Herefordshire
A spectacular large polished labradorite freeform sourced from Madagascar. Characterised by its iridescent colours, principally blue, this huge high grade labradorite is a stunning specimen, the lustrous colours fluctuating as it is observed from different angles. It is freestanding, making a striking sculptural piece for an interior, with a polished face to one side and a naturalistic reverse. Labradorite is named after the region of its discovery at Paul Island in the Canadian province of Labrador, first discovered here in 1770. Madagascar is currently the main source of labradorite. To expose its stunning colours, the stone is highly polished, revealing its natural beauty. This in itself is a talented skill, with only a small percentage of labradorites yielding positive results, making this specimen a rare discovery. We also have two other large labradorite...

Sculptural Oriented Meteorite
Located in London, GB
Oriented Chondrite Meteorite Circa 4.56 Billion y/o Chondrite 24 x 20 cm, 28 cm tall on base 7.1 kg A sculptural and beautifully weathered chondrite meteorite; upon entering the atmosphere, this extraterrestrial stone would have heated the surrounding air to a temperature of over 1700 C, higher than that of the hottest lava on the planet, and enough to melt away its outer layers, leaving its surface rippled with regmaglypts, thumb-shaped impressions formed as superheated rock streaked off of the main body as it careened toward the earth. The last layer of the rock to melt would have re-solidified as the meteorite made impact, forming a charcoal coloured fusion crust, which has taken on a deep ochre-tinted patina. Chondrite meteorites such as this example were formed at the very beginning of our solar system, by the accretion of various types of dust and small grains, adrift in the vacuum of space and, as such, provide important clues about the birth of our own planet. This piece is an especially rare specimen, known as an oriented meteorite...
