So, what exactly does obsidian look like?Obsidian is a glassy-looking, very fine-grained (aphanitic) rock that is usually black but may also be translucent, rust-red, dark green, or iridescent. Inclusions of white ‘snowflakes’ are common. Obsidian is very smooth, with scoop-shaped conchoidal fractures that often result in sharp edges when broken.ObsidianPro Tip: I have created the best rock identification system you’ll find anywhere. It’s made to help everyone from brand new hobbyists to university Geology students, and includes an eBook, digital tools, a video tutorials. Find out more here!While all obsidian meets this general description, there is a pretty wide spectrum of obsidian that can look significantly different from one another. Their differences in appearance are primarily driven by the impurities contained within the silica-rich magma at the time of formation.Color is Driven by ImpuritiesObsidian primarily consists of silica which, given more time to crystallize, would become quartz crystals. A typical obsidian specimen contains about 70% silica, with the remainder consisting of other elements like aluminum, sodium, and oxygen. It is these impurities that give obsidian its color, and depending on their relative amounts that color can vary from location to location.Black obsidian, which is the most common and well-known variety, occurs when there are relatively large amounts of tiny inclusions of mafic (dark) minerals like hornblende, pyroxene, and magnetite. Even black obsidian is translucent – meaning light will pass through it. If you hold up a small flashlight behind a piece of obsidian you can see through even the darkest.

Most people are familiar with obsidian thanks to its distinct glassy appearance. It is very popular with collectors, and it has plenty of practical applications. It can be found in specific locations all around the world, making it relatively accessible to collectors.When most people think of obsidian they picture a black, glassy volcanic rock. While this is generally accurate, there is a lot more intricacy and variety when it comes to obsidian which can sometimes make it more difficult to identify. However, identifying obsidian and its many varieties is a relatively simple process once you know what to look for.Obsidian is a glassy, extrusive igneous rock with a felsic composition, and is typically black in color but may also be rust-red or display whiteish ‘snowflake’ inclusions. It often displays conchoidal fracturing with very sharp edges. Obsidian is made from the rapid cooling of silica-rich lava.While obsidian is a clearly defined rock type, there are many different varieties that can appear quite different from one another. I’ll walk you through how to identify obsidian, what different varieties look like, and where it can be found.What Does Obsidian Look Like?Most people with a passing knowledge of geology are familiar with obsidian (or at least the most common variety of obsidian). However, sometimes obsidian isn’t as readily identifiable as you might think. It can grade into other rock types, making it difficult to distinguish. Perhaps you have found a less common variety that doesn’t match your preconceived notion of what obsidian looks like.Black Glassy Set by Thvg on DeviantArt
Obsidian specimens.Red or rust-red obsidian occurs when there are microscopic crystals of minerals like limonite or hematite. It is common for rust-red coloration to be mixed with black, giving the obsidian a splotchy appearance. This variety is often referred to as ‘mahogany obsidian’ due to its resemblance to the wood of the same name.Other colors of obsidian are possible based on the types of impurities in the cooling lava. Rainbow obsidian (one of my favorites) is likely the result of various types of microscopic feldspar crystals aligning themselves preferentially during cooling and solidification.Pro Tip: To get a better look at the crystals in your rocks and help with identification I highly recommend picking up a good geologist’s hand lens. I use this one that I got on Amazon.Transparent or nearly clear obsidian is very rare, and requires an extremely silica-rich lava with little to no impurities.The white coloration seen in snowflake obsidian is a result of a secondary process that occurs after the obsidian’s original formation. The glassy texture of obsidian is very unstable, and over millions of years, the silica will reorganize itself to form radial quartz crystals that look like snowflakes. Over enough time this causes the obsidian to lose the glassy appearance over much of its surface.Texture of ObsidianOne of the defining features of obsidian’s appearance is its texture. All obsidian is glassy and very fine-grained, meaning that you cannot see the individual crystals in the rock, even with high-powered magnification.Glassy texture is a sub-texture of ‘aphanitic’,Glassy Starter Set (black) - Sodafresh

Up with new lines marking the routes of our European bike tours. Maybe someday we’ll have a wall big enough to display it again, and I’ll fill in the blanks for all of our tours since then. And finally there’s this priceless item, the hand written set of essays I started writing in 1975, the year Carol, Shawn and I moved down to a farmhouse in the middle of the grass fields northeast of Salem, me apparently envisioning myself as some sort of 20th century Thoreau. Now that should make an interesting read on a cold winter night. It was the 70’s, remember? Cut me some slack. And there’s this, my oldest belonging, picked up in the summer of 1956 when I found a crusty, rounded boulder in the woods high on Mount Rushmore and smashed it open. I’m wandering around in the woods while the rest of the family was waiting beside our black 1949 Chevy. We’re on our way back to the PNW from West Virginia, and they’re waiting because the car has overheated and its radiator is steaming. I can still feel the thrill of viewing its bright pink, glassy interior. Rose quartz. I pocketed this small chunk, and kept it for 68 years now,.

Topaz is a favorite mineral for many and it makes a great substitute for cheaper and an alternative gemstone for jewelry. It has a little more complicated chemical formula at Al₂SiO₄(F,OH)₂ than some other silica type minerals. The mineral topaz in its raw form is also quite a collectors item for rock and mineral collectors. Most identifying traits of topaz will be while it is in its raw state and not cut into gemstones. Some Key Visual Looks of TopazWhen it comes to identifying the mineral Topaz there are some distinguishing features that can set it apart from other minerals. If you have examined topaz enough, these features can end up being easier to note. You can visually identify topaz by the following looks it will have:Its surfaces: Topaz has vitreous, glassy, and shiny surfaces.Its crystal shape: The mineral topaz is in the form of a crystal.Uniformity: The crystals are uniformly structured throughout its length until the part where it goes to a point. Distinct number of sides: Its crystals typically have 4 sides which have the shape of a diamond. Formation: It can form within clusters around bits of host rock from all sides.Its colors: Topaz is commonly found as a clear and colorless crystal, but can come in colors such as black, blue, brown, brownish-yellow, gray, green, orange, pink, red, yellow, and white.Host Rock: Its surrounding host rock is commonly granite and rhyolite that is rich in silica.Streak: When running a streak, or scratch test, it has a streak of white.The way it breaks: It can easily break along the horizontal axis of weaker parts in the crystal. There are some common features that make it difficult to identify topaz from other minerals. One being that there are many different types of minerals out there that are in crystal form. The items I have listed above should help in better distinguishing topaz from those other crystal type minerals. Some Different Looking Topaz VarietiesTopaz can come in a few different varieties. Those varieties are generally based upon the different colors that topaz can take on. A few colors of topaz can be quite rare and have even received some unique names. Some topaz varieties that have a different look will include:London Blue Topaz: A very popular and deeper blue type of topaz.Sherry Topaz: A very light brownish and orangish topaz. Sometimes looks a little yellowish.Glacier Topaz: This topaz is.

And it forms when lava cools very quickly on or near the Earth’s surface, denying the crystals enough time to nucleate and grow before becoming completely solidified.As long as the specimen is clean and free of dirt or dust, the surface of obsidian will feel very smooth and even slippery to the touch. The exception is snowflake obsidian, that can sometimes feel a bit rougher due to the re-organized quartz crystals (snowflakes).How to Identify ObsidianObsidian is so distinct looking and relatively recognizable that you might think that identifying it is a trivial matter. While that is often the case, that mindset often leads people to misidentify other rock types as obsidian. It is important to take a more methodical approach when identifying obsidian.To identify obsidian, first look for a glassy texture with no visible grains in the matrix, even under magnification. Observe the surface of the rock and look for conchoidal fractures and sharp edges. Finally, hold the rock to a light source to check that it is translucent, allowing light to pass through.A rock must meet all of these requirements to be considered obsidian:Igneous – Formed from cooling lava, with interlocking crystal grains.Very Fine-grained – Glassy and aphanitic texture with crystals invisible even under magnificationFelsic Mineralogy – High quartz and feldspar contentConchoidal Fracturing – Scoop-shaped surface when broken, common to all glassesSnowflake ObsidianIf your rock meets all of those criteria then it is very likely obsidian, or at least something very closely related. People sometimes make the mistake ofComments
