11g of waterworn amber from the beaches near Homer, Alaska; this town is situated on the shores of the Cook Inlet on the western half of the Kenai Peninsula, south of Anchorage. A few geological Formations (Kenai Group) in the nearby area contain coal reserves, but mainly the Beluga Fm. is exposed along the beaches of Homer to Anchor Point: this Formation is of freshwater origin, and comprises layers of sandstone, siltstone, and coal. The Pliocene-aged Sterling Fm. is located slightly farther inland, with numerous streams cutting through it and emptying into the Cook Inlet, however this Formation does not contain much coal. There were a few coal mines north and south of Tustumena Lake, back in the late-19th to mid-20th centuries: the Bluff Point Mine, west of Homer, was active from 1899-1951.© Kaegen Lau

Small specimen of red-skinned blue amber from the La Toca Mine. Piece weighs 2.4g and measures 26x18x16mm. There are a few dendritic inclusions of moss, and as a whole, the piece is free of fractures and quite clean. The blue fluorescence is caused by certain hydrocarbons (i.e., perylene) that formed within the resin over its millions of years of burial; fluorescent hydrocarbons in amber are believed to be formed due to several possible factors: fire, geothermal or volcanic heat, prolonged submergence in a marine or lacustrine (lake) environment, etc. This specimen was partially polished and illuminated with 140 lumen LED light (yellow phosphor).© Kaegen Lau

A sizeable specimen originating from the La Toca Mine, Cordillera Septentrional, Santiago Province, Dominican Republic; specimen weighs 145.0g and measures 120x88x40mm. There are numerous visible flow lines, which are evidence of successive resin flows, each previous layer being slightly oxidized (discoloration): most of the layers in this piece are coated in small particulates. This piece is a transverse section of what was once a massive flow of resin-turned-amber, as evidenced by the raw outer "crust" with slight matrix on its three sides; the flow was likely formed as resin traveled downward along a deep groove in the resin-producing tree's trunk. There are no observable insect inclusions.© Kaegen Lau

Incredible blue fluorescence in amber from Tiger Mountain, Washington State, U.S.A. No longwave UV light has been used here; these select pieces fluoresce in the same LED light conditions as Dominican blue amber, and with a strikingly similar coloration. Commercial quantities of blue amber have been officially described to be found in the Dominican Republic, Indonesia, and Mexico (Chiapas); to my knowledge, blue amber has never been described, much less documented, from North American deposits. Total weight is 0.4g, each piece measuring only a few millimeters in length. In the fluorescent video & image, specimens were submerged in water in a borosilicate glass petri dish; also, an additional video and image of the subjects when dry. *Please note there are several condensed air bubbles on surfaces of amber and glass.

Hello, I'm thinking of adding some Dominican amber and Mexican Chiapas amber to my collection, but as always authenticity is a concern especially when buying online so I wanted to get some feedback as best as I could. Here's what I'm looking at: 1. Mexican Chiapas Amber with leaf. Seller has provided image under UV/black light so likely real? Also shipping directly from Mexico and the seller has a bunch of other authentic-looking ones. 2. Dominican amber with Ponerine winged ant and flies, 1.4 cm wide. I asked for photos under UV light and seller didn't provide any but instead said this is not a reliable test so I'm a bit concerned. Specimen itself also looks almost too clear/clean, though I'm aware Dominican amber is generally much clearer than other ambers. What do people think? Thanks.

Ethiopian Amber (Debre Libanos Sandstone; 23-16 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
4.7g polished specimen of amber from one of several deposits near Alem Ketema, Amhara Region, Ethiopia; piece measures 35x24x17mm. This view of the specimen displays organic detritus inclusions: in particular, a long fibrous subject (at center, beneath fluorescent layer) can be seen. The green coloration is partly due to the amber's autofluorescence initiated by the LED light (transmitted) during photography; the clear portions of this specimen present a yellow-green base color in incandescent light, and emit a greenish fluorescence in sunlight or LED light. Ethiopian amber deposits have been described relatively recently (2010), and the amber occurring in the siltstone layer of the Debre Libanos Sandstone was initially believed to be Cretaceous in age; later studies have proven the initial determination to be false, and further study of palynomorph and insect inclusions have provided a new estimated age of Early Miocene. The amber-bearing layer is over- and underlain by basaltic layers, some of which display columnar jointing; volcanic-derived pressure and heat has naturally changed the base color of some of this amber to varying shades of green. This amber is also believed to possibly have been produced by a member of the Hymenaea genus.© Kaegen Lau

From the album: Fossil Amber and Copal: Worldwide Localities
4.7g polished specimen of amber from one of several deposits near Alem Ketema, Amhara Region, Ethiopia; piece measures 35x24x17mm. There is a thin vein of transparent material, while the rest is heavily included with organic detritus; some small fragments of plant material are seen in the transparent portions (see associated photo). The green coloration is partly due to the amber's autofluorescence initiated by the LED light (transmitted) during photography; the clear portions of this specimen present a yellow-green base color in incandescent light, and emit a greenish fluorescence in sunlight or LED light.

I thought I had seen the whole gamut of shapes and materials from the Lee Creek mine spoils, but this tiny (2cm) specimen has me stumped. It looks like a tiny brain with “folds” radiating away from a central seam. The “bottom” has a deeper seam, like the meeting of two halves of a walnut. I have found blocks of milky amber in North Carolina before, but nothing with any symmetry. if it’s a coprolite, what’s the seam? Could it be a little skull cast? I have been staring at this thing for a year. Please help. Frank

I found these two pieces on a gravel road along with bucket loads of other petrified wood. It was brought in with other large rock and put on a dirt road near my home. (West Monroe, Louisiana) Therefore, I’m not sure of the exact location from which this came. I was wondering if this was amber that had been petrified with the wood somehow? If it’s not amber, any suggestions as to what it is? Second piece

I found this piece while looking through a kilo of Amber and it's a bit different to the usual - there is something distinctly fibrous inside. Usually its the internal patterns of the Amber but this isn't. Unfortunately, its super hard to photograph. I think its probably something like mold or pollen, although I can't see any distinct seed pods etc - going to clean it up a little more tomorrow. I'd appreciate any input. Thanks, John

Hi everyone, I haven’t been on in a while, how is everyone? I am posting today in hopes of getting an ID. Backstory, a while ago, I was able to purchase a piece of “polished amber with insect,” on online. When it got here, I was skeptical about whether it was real amber or not. I did a LOT of testing. It passed the float test, the UV test, and I was able to calculate its specific gravity successfully. I am pretty sure it’s real amber. Today, I took the amber out and looked at the insect under my microscope. At 40x magnification I saw so much TINY detail, I now believe it is not fake at all. I doubt anyone can make details this tiny. Now the question, is it possible to ID this insect? I am currently looking for an old email that has the details on where it was found and what type of amber it is. Any help will be appreciated, Jared

Hey everyone, I need your help! I recently bought a mystery box with some ambers and i got this one with...something inside. So I took my microscope and took some photos (don't remember the magnification but i think 80-100x) and...still didn't know what it could be! Help please? Age of the amber: 49 mya (Middle Eocene) Origin: Lithuania (sorry for eventual bad photos, my microscope isn't that good)

Hello, I recently purchased this piece of Baltic amber with an insect inclusion. Don't have it in hand yet so can't do the more exhaustive tests, but I was wondering if someone could help identify the insect inclusion, and at least visually assess if it seems legit? Regarding ID I'm thinking it might be a Caddisfly, as it is quite large (~1cm) and seems to have 2 pairs of hairy wings and very long antennae. Regarding authenticity I don't see any visual red flags, and it also doesn't seem to be an inclusion fabricated in real amber as afaik there would be faint swirls around the inclusion where it was melted in with molten resin or copal. The seller also sells a variety of other amber products and jewelry so they seem quite legit. Thoughts? Thanks.

Hey-O! This mid western fossil hound is heading to Punta Cana for a vacay with the wife but the fossil hunter in me needs more to do than let the ladies gaze at my miraculous beer belly! haha I'm doing research into the area we are staying and I'm wondering if this would be a good area to sift for fossilized teeth or bone. I know PC is guarded by a reef, so modern shark teeth are unlikely but I'm not sure where this land mass sat throughout our eras. Any advise would be appreciated. I know the Dominican Republic is know for their Amber mines (which would be cool). Any feedback would be appreciated! Thanks all! Steve D!

Hey guys new to the forum! I have a piece of petrified wood that looks to have both copal and amber veins in it. I know how almost impossibly rare this can be but this has passed every test for amber that could be done outside of a lab. I am getting it verified in a few days. Would like to get the communities opinions on this piece. Thanks.

From the album: Fossil Amber and Copal: Worldwide Localities
Triple-phase inclusion and a few in-focus single and dual-phase inclusions nearby. The triple-phase bubble is a narrow chamber, possibly part of a methane termite (incomplete, heavily oxidized); there are two organic solids, the larger preventing the migration of the gas bubble. These inclusions are contained within the 5.4-4.7g specimen depicted in the four related photos. This image was captured using a Samsung WB35F while holding a BelOMO 10x loupe between the lens and specimen.© Kaegen Lau

Dominican Amber (La Toca Fm., 20.43-13.65 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
4.7g piece of amber from the La Cumbre Mine, measuring (mm) 25x22x15. Seen at the base of the specimen is a natural fracture that was infiltrated and completely coated by marcasite during the resin's diagenesis, in a thin film that began at the previously rough, unbroken exterior (underside of specimen in picture). There are dozens of visible dual-phase, countless single-phase, and at least two triple-phase bubbles. These are easily seen in the other four related photos of the finished specimen. "Pyrite disease" is a major concern with this specimen; even with preservation in an airtight container, oxidation is still possible, given the presence of gas/liquid inclusions, and the fact that water and gases do penetrate and migrate within amber over time. Portions of the piece may be doomed, but it is interesting while it lasts.© Kaegen Lau

4.7g piece of amber from the La Cumbre Mine, measuring (mm) 25x22x15. It has a couple marcasite inclusions: seen here is a protruding portion (one half remains inside the piece) that was perhaps a gas bubble, but later infiltrated with iron and sulfur in solution during burial, migrating via a fracture/microfracture; or it may be a permineralized organic/inorganic inclusion (shell, quartz pebble, etc.), which are documented in amber from the La Cumbre deposit, and is called "double fossilization": while this occurs in tiny grains of younger La Cumbre amber which were deposited after the older amber seen here, it is possible it is seen in this older La Cumbre material. Another example of double fossilization is known from fully pyritized insects with marcasite interiors, recorded from cretaceous amber in NW France. There are dozens of visible dual-phase, countless single-phase, and at least two triple-phase bubbles. "Pyrite disease" is a major concern with this specimen; even with preservation in an airtight container, oxidation is still possible, given the presence of gas/liquid inclusions, and the fact that water and gases do penetrate and migrate within amber over time.
