I don’t know from which locality this specimen originated. I found it among my late grandfather’s property. From what I can gather, this is an extremely large specimen of amber. It weighs approximately 110 lbs, measures approximately 22” x 18” x 11” and features many interesting inclusions from what i can see. I’ve performed a scratch test, hot needle test, acetone test, smell test, saltwater test, UV light test, and specific gravity test… all of which seem to confirm its identity as amber. If this is true, however, based on the information I can find, it would seem that I’ve come

6.4g specimen measuring 40x25x14mm (see related entry). This is incredibly-rare material, with next to no information available on it; this copal originates from sandstone deposits and can be found both in-situ and ex-situ. This particular specimen was recovered from a farmer's field in rural Costa Rica many years ago, and is part of a small lot of similar material; unfortunately, the specific location of the deposit this specimen came from is unknown. This material is noticeably harder than Colombian copal, but still reacts to acetone; the exterior of this piece has a slight layer of sandston© Kaegen Lau

This specimen weighs 8.5g and measures 34x29x20mm. It contains several dual-phase bubbles (some with mobile gas bubbles), with one being quite large; a translucent layer surrounds most of the chambers. The piece originated from the La Guajira Department of Colombia, and was recovered from deposits/diggings several miles south of the Cerrejón Coal Mine; the depth(s) of these diggings, and the copal-bearing sediments' geological age are unknown, though some sources claim it comes from the same Paleocene strata found in the Cerrejón mine to the north.

Indonesian Red Copal (Subsoil to Surface Horizons, Late Holocene)
Barrelcactusaddict posted a gallery image in Members Gallery
From the album: Fossil Amber and Copal: Worldwide Localities
This specimen weighs 36.0g and measures 65x40x25mm; several small fragments of plant material are contained within its translucent, reddish mass. Originating from the island of Java, this variety of copal is a fairly recent discovery; it is recovered from various soil levels, near to or on the surface of the rainforest floor. Rough specimens usually exhibit a thick, whitish exterior crust; Indonesian red copal is very soft, reacts readily with acetone, and can be scratched with a fingernail. -

Hand polished piece of Madagascan amber Copal. This Copal has not had a definite date put upon it yet, but it is thought to be a similar age to the Columbian Copal, so that would place it in the Pleistocene age until more accurate dating. It is thought that similar environments around the world at that time created amber copal that has formed almost identical to each other and the insects are similar too, if not the same, just like today. Copal Size: 5.5cm -
I recently obtained this piece of amber, which was described as being from Myanmar, and therefore of cretaceous age. I got it very cheaply, I'd say (from a well known auction site), and this led another collector to rather rudely assert that it was fake. I have no reason to assume that it is fake, but at the same time, I'm having trouble proving that it's authentic. When I poke it with a hot needle, the needle makes an impression but doesn't slice straight through it. Dark grey smoke rose from it, which didn't smell of plastic. When I rub it vigorously with a soft clot

I’m a fisherman and I’ve just done a trip on a Beamer trawler. We were fishing 20 miles south of lizard point in Cornwall and caught this in one tow. The skipper and his father both said they’ve seen this before but it’s not common, neither knew what it is exactly. It was in one lump but my fellow crewmen hit it with a rail pin and it split. Can anyone tell me what it is? It’s very pretty and I can see loads of inclusions when I hold fragments up to the light. It also smells strongly of pine.

Hello everyone! I was just curious as to what you think of this specimen. I'm aware users here are (understandably) very sceptical of lizards in amber/copal, so I'd love to hear what you have toto say about it. Here are the details: Species is unknown From Colombia, thought to be from Pliocene/Pleistocene The lizard measures 30 millimetres. Total measurement with copal is 50 x 40 x 0.50 mm Full image: Base - partial tail and leg, with one foot visible on the right Torso - possible predation? Also note the little stump where th

I was encouraged to share this in the forum so here it goes. I was given a pile of "amber" and two pieces that may or may not (most likely not) have something inside. After the "amber" failed the saltwater float test it was proposed that I may have copal, NOT amber. I tried my best to take as clear of pictures as my camera phone would allow. The first piece supposedly it has a "bug or stick or something" inside. The copal, if it really is copal, does not appear very clear, even with a light source behind it. The second piece is a little more transparent when the light shines throug

I bought this bit of Madagascar copal a year ago, then finally got a decent microscope to see the bugs this week. They are less than a mm each. Now I'm stumped. I am a certified *modern* naturalist. I know something about insects. This one fits all the defining characteristics of an adult insect - probably Coleoptera - except that I only see four legs and may or may not have had antennae at some point. The heads are not very clear at any angle. On the bottom view, there are nubs at the end of the abdomen that *could* be legs, but that is the wrong place for insect legs. On the side views, it l

I inherited a friend's mineral collection. Lot's of interesting specimens of turquoise, petrified wood, crystals, etc. He lived in New Mexico and I know some of the pieces are from U.S. southwest area. That's about all I know. This one's a mystery, and he really didn't have any idea either where it came from. Has a strangely organic look to it though. Any insight or thoughts will be appreciated. Thanks!

This is my fossil collection please show us yours!!! These are my display fossils only The first picture is a large unidentified fossil shark tooth I recently bought from a local fossil store. The second is my display collection I put fossils in once they have been prepared or bought. The next photo is Madagascar copal it is about 9 million years old and it has multiple inclusions including fly's, wasps, and spiders. The next is an unidentified fish fossil in good shape but not too valuable. The fifth fossil is a trilobite (paralejurus) in Devonian limestone it is 385 m

I newely collected this copal. But, there are lots of crazing on it't surface. I can sure it is copal because i do acetone test so this is more weak then amber. I thinking about grinding this nicely with soft cloth and tooth paste. I want to know it is ok to copal, and how to store it without crazing. Thanks for your help, and apologize to my short English...

From the album: MY FOSSIL Collection - Dpaul7
Copal SITE LOCATION: Columbia TIME PERIOD: Recent Era (several hundred to several thousand years old) Data: Copal is a name given to tree resin from the copal tree Protium copal (Burseraceae) that is particularly identified with the aromatic resins used by the cultures of pre-Columbian Mesoamerica as ceremonially burned incense and other purposes. More generally, the term copal describes resinous substances in an intermediate stage of polymerization and hardening between "gummier" resins and amber. The word copal is derived from the Nahuatl language word copalli, meaning "incen -
I bought this a few years back and I was wondering if it was amber, copal or plastic. It was labeled as Baltic Amber and it has a spider inclusion in it. Are there any tests I can do to it that are pretty reliable and will not ruin it. I put it in salt water and it sunk to the bottom. Not sure if the mixture was correct. I have a saltwater fish tank and I used water from it for the test because it is the same mixture as ocean water. Thanks for any help.

I have been doing some recent work with Columbian Amber/Copal and thought I would throw this out for a general discussion. It is fun, if nothing else Most of my life I have believed that there is no difference between Copal and Amber. I know chemically there is no difference between the two. Amber/Copal from the same plant from different time periods, even millions of years apart are identical. Fossil resin's molecular make-up is mostly carbon and hydrogen atoms that form hexagonal rings. Molecular bonding between the rings increases over time (called polymerization, as in moder

I really want to collect mammal fossil. i can trade basilosaurus fossil, trilobite, nice copals, korean plant fossils and others. i want mammal skull fossil, jaw bone, and bone(can be from anyone). if you want to trade, send PM to me. thanks + l'm from South Korea. +i attached some my fossils pictures.

i bought this piece a while ago, it was listed as "amber" but is actually copal. there are a lot of insects in the piece including an ant, some weird fly-like insects, another weird insect, some kind of roach, etc. it was quite hard, and was about NZ$7. i don't know what kind of copal it is and i am hoping someone may be able to shed some light on this.

Massive Kauri Copal Find With Bark Injury Attached!
NZ_Fossil_Collecta posted a topic in Fossil Hunting Trips
today i found a virgin copal site, A.K.A i found another creek in the forest. this creek in particular was more ideal than others i had hunted in before because is had eroded more steeply. what i mean is that the creek bank was quite sheer in some places, which is perfect for finding kauri copal because your digging is done for you. this particular piece was spotted while i was getting into the creek to look for kauri copal, i saw it and gave it a slight kick with my gumboot (wellingtons for the non kiwis out there) and saw the copal underneath. after a good heave and tug to get it out of the -
Ok, so a few of you have heard me rambling on about that Kauri gum i found a while ago but up until now i haven't got around to giving you pictures. well, here is a picture of a polished piece of the stuff. ~90% of the lump we found was milky and mostly opaque but there was a large pocket of clearer copal in one part, the piece in the picture is a piece of that pocket. i then polished it up with Brasso and a rag, and now it shines beautifully. me, and occasionally my friends, will be hunting for some more of the copal so you can expect to see more pictures in future. Insects, you ask? as of ye

hi, so me and my brother and my friend went into the small forest behind my house, and we were digging around in a muddy stream (the mud is very gloopy and your feet can sink in it a bit) , we found this MASSIVE stone (that's what we thought) it had something that looked like wood sticking out of it, although the wood's sides were straight and it looked like some kind of fence post. we smashed open the 'stone' with our spades and behold: a cream-coloured, hard, glass-like substance. it has a strong, almost chemical-like aroma, similar to the aroma of a root we split while digging. it was irreg

i bought a piece of amber from a shop for $7 (NZ) and it was in a little tray with other pieces all called 'amber' and not specifically listed as having bugs in them. i tried the fingernail test and on one side it scratched a really tiny bit and on the other side barely at all. i think it was baltic becuase it was sold alongside gems. it has lots of insects inside and is irregular both outside and inside. is a little misty on one side, has an ant, some kind of fly larva, maybe a couple of midges, another fly. it was with other pieces with no inclusions. is it copal or amber?
