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.
This piece has been cut to showcase the beautiful green olivine crystals. It would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card. Stand is not included.

Tanzanite is renowned for its intense blue and violet colors, but can also be golden, green, lilac and peacock (blue and green). The sole source of tanzanite is the Merelani Hills in northern Tanzania. Discovered in the 1960s, tanzanite is considered rarer than diamonds due to its single-source origin. The mines in Tanzania are exhaustible, adding to the gemstone's allure.
With a hardness of 6.5 to 7 on the Mohs scale, tanzanite is relatively soft compared to some other gemstones. As a result, it requires gentle care to prevent scratches or damage.
Tanzanite is believed to aide with spiritual awareness, insight, and communication. Some attribute it with calming energies and the ability to enhance psychic abilities.
These are cabinet-sized Hourglass Selenite Crystals from Salt Plains, Oklahoma. Oklahoma designated the unique hourglass selenite crystal as the official state crystal in 2005 after elementary school students from Bryant and Red Oak School petitioned the state legislature. Hourglass selenite crystals are found only on the salt plains of Oklahoma, a unique 11,000-acre geological area. The salt plains were formed by repeated flooding by sea water millions of years ago.
Selenite (hydrous calcium sulfate) is a crystallized form of gypsum, a common mineral in sedimentary environments that can take on a great variety of crystal forms and shapes. Crystals take on the characteristics of their environment - iron oxide in the soil gives the hourglass crystals their chocolate brown color.
Hourglass Selenite is thought to amplify energies, aid in achieving balance and harmony, and align the crown chakra. Its protective qualities are believed to ward off negativity, and it is often used to enhance communication and promote emotional stability.

Crackle quartz, also known as fire quartz or ice quartz, is a type of quartz that has been treated to create a distinctive cracked or shattered appearance within the crystal. This treatment is done by heating the quartz crystals and then rapidly cooling them, which results in the development of internal fissures. The cracks within the quartz can vary in size and pattern, creating a shattered or broken appearance. The fractures often resemble ice or fire, giving rise to the alternative names ice quartz and fire quartz.
Crackle quartz is available in various colors, and the treatment process can enhance or alter the natural color of the quartz. Common colors include clear, white, smoky, or even vibrant hues like pink, blue, or green.
