These are whole, uncut lava coated volcanic bombs from Mortlake, Victoria, Australia .  The lava crust on these pieces is complete, they can be showcased as is or cut to show the interior. The lava is most likely covering green olivine crystals.

An olivine volcanic bomb is a type of volcanic rock that contains olivine crystals and has been ejected during a volcanic eruption. Olivine is a mineral that is commonly found in the Earth's mantle and is one of the first minerals to crystallize as magma cools.

Volcanic bombs are large clots of lava that are ejected from a volcano during an explosive eruption. They can vary in size, and their shapes are often streamlined due to their molten nature as they are thrown through the air. When these volcanic bombs contain olivine crystals, they are referred to as olivine volcanic bombs.

The dimensions and weight of each of these olivine bombs are as follows:

A.  32x25x17 mm / 1.3x1.0x0.7 in  |  14.2 gr / 0.5 oz
B.  37x25x22 mm / 1.5x1.0x0.9 in  |  23 gr / 0.8 oz
C.   43x34x21 mm / 1.7x1.3x0.8 in  |  37 gr / 1.3 oz

E.  66x44x33 mm / 2.6x1.7x1.3 in  |  113.5 gr / 4.0 oz
F.  79x48x38 mm / 3.1x1.9x1.5 in  |  145.4gr / 5.1 oz

Any of these Olivine Bombs would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card. 

Microcline is one of the most common feldspar minerals. It can be colorless, white, cream to pale yellow, salmon pink to red, or bright green to blue-green. Microcline forms short prismatic or tabular crystals that are often of considerable size: single crystals can weigh several tons and reach yards in length. Crystals are often multiply twinned, with two sets of fine lines at right angles to each other. This gives a plaid effect that is unique to microcline among the feldspars.  The nice patch of Quartz crystals makes this a spectacular piece. 

This is a quality specimen that would be a beautiful addition to any new or existing rock collection.

Quartz crystals are among the most abundant and well-known minerals on Earth. It belongs to the hexagonal crystal system, and typically forms six-sided prismatic crystals with a pointed termination. Its crystals can be colorless or exhibit a wide range of colors. The color variations are often due to the presence of impurities or trace elements during the crystal's formation. Quartz is transparent to translucent.

Quartz from this quarry is known as the best of its kind. These specimens have a unique brightness and surface sparkle preferred by collectors around the world.  The crystals are intergrown with many others in jackstraw groups which are not attached to matrix: giving you an unlikely-looking floater specimen. The specimen is in very good condition.

This is a beautiful and colorful specimen combining green Apophyllite, Stilbite and Laumontite.  It is a large specimen and is in excellent condition.

This crystal cluster brings harmony and emotional support to any space, encouraging heart-centered energy, mental clarity, and grounding.

Stilbite is a zeolite mineral appreciated for its delicate crystal formations and pastel hues, ranging from colorless to white, yellow, pink, and peach.  It forms distinctive tabular crystals with a bowtie or butterfly shape and exhibits a vitreous to pearly luster. 

One of the distinguishing features of apophyllite is its ability to form well-defined crystals with a pyramid-like shape. These crystals often exhibit a prismatic or pseudo-cubic habit and have a vitreous luster. Apophyllite is transparent to translucent and is commonly found in colorless or white varieties, although it can also occur in shades of green, pink, yellow, or brown.

Laumontite is a member of the zeolite group, and occurs in many of the zeolite deposits.

We have for you a small floater crystal of gypsum var Selenite in a perky box found 1962 in Ellsworth Mahoning County, Ohio U.S.A.. 

Gypsum is one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters. Since it forms easily from saline water, gypsum can have many inclusions of other minerals and even trapped bubbles of air and water.

This specimen has no damage and will ship in its protective display box.

Volcanic bombs are large clots of volcanic lava rock that are ejected from a volcano during an explosive eruption. They can vary in size, and their shapes are often streamlined due to their molten nature as they are thrown through the air. When these volcanic lava rocks contain olivine crystals, they are referred to as olivine volcanic bombs.

Mount Shadwell, a dormant volcano, was formed 25,000 years ago and is believed to have last erupted about 5,000 years ago. The town of Mortlake, which is situated at the foot of the volcano, is the self-proclaimed olivine capital of Australia.  This is where large ejected rocks from Mt Shadwell, called volcanic bombs, are found.

This huge museum piece has been cut to show the green olivine crystals which are showcased beautifully against the surrounding black lava crust.
