Sumatra Blue Amber (Sinamar Fm., ~30 Ma)
Barrelcactusaddict posted a gallery image in Members Gallery
From the album: Fossil Amber and Copal: Worldwide Localities
Palm-sized piece roughly 80g in weight. There is a very thin layer of coal on the top and bottom of the piece, making it a good example of a seam-type formation. It's blue coloration is purely surface fluorescence, initiated in this case by a 140 lumen LED light; this fluorescence (especially under a non-LW UV light) is caused by the presence of an exceptionally high concentration of various hydrocarbons contained within the amber.© Kaegen Lau

Sumatra Blue Amber (Sinamar Fm., ~30 Ma)

4.3g dark, transparent blue amber from West Sumatra. After grinding and polishing, I was surprised to discover that it contains 2 ants and 2 winged ants (possibly wasps); these were a little tricky to photograph, due to the amber's strong fluorescence under 140 lumen LED light, so these inclusions had to be backlit. I used a Canon EOS 500D, Canon 60mm f/2.8 Macro Lens, and combined 2x and 4x Hoya circular magnifier lenses (8x).© Kaegen Lau

4.3g dark, transparent blue amber from West Sumatra. Lateral view of the same Psudomyrmex inclusion in the previous entry. The antennae appear to have clubbed tips, but each is actually coated/overlain by a congealed drop of resin within the amber itself (this type of suspended resin formation is characteristic of and common in Indonesian amber).© Kaegen Lau

4.3g dark, transparent blue amber from West Sumatra. This inclusion is most likely a winged ant of the Pseudomyrmex genus, although it may possibly be a wasp. A positive identification of both winged subjects is challenging, due to their deteriorated state and their position within the piece.© Kaegen Lau

1.2 gram amber from Tiger Mountain, King County, WA. Smaller inclusions consist mostly of slightly darker, congealed resin positioned along natural flow lines; this feature is by far most commonly seen among the Indonesian ambers. The few large, dark masses are botanical debris. Image taken under approx. 10x magnification with a Belomo Triplet loupe. This amber is middle to late Eocene in age (about 41.3-33.9 Ma), and comes from coal seams along the boundary between the upper Tukwila/lower Renton Formations.© Kaegen Lau

Two exceptionally fluorescent pieces of amber from Tiger Mountain, King County, WA. These were illuminated with a 140 lumen LED penlight, not a long wave UV light; this is a surprising feature for amber of this locality, as blue amber is only well-documented to come from the Dominican Republic, Indonesia, and Chiapas. This amber is middle to late Eocene in age (about 41.3-33.9 Ma), and comes from coal seams along the boundary of the upper Tukwila/lower Renton Formations.© Kaegen Lau

Two pieces, roughly weighing 7 and 4 grams respectively. Both are mined from the Rivne region of Ukraine's Rivne Oblast, and had a little to no oxidized layer, in comparison to amber mined from the nearby (roughly 50 km) Klesiv Deposit.© Kaegen Lau

Roughly 12g specimen of amber mined from the Klesiv Deposit of the Rivne region in the Rivne Oblast of Ukraine. It was originally coated in a 2mm red oxidized crust, typical of this locality. It is believed that the presence of this crust is an indicator that amber from this particular locality underwent little to no re-deposition throughout its diagenesis, and oddly contains the majority of described insect-included Rovno material.© Kaegen Lau

19.0g specimen of hand-polished amber from the Rivne region of Ukraine. It contains numerous botanical debris, although I have not observed any definitive insect inclusions. It is what would be termed a "run"; this specimen has over 12 successive layers that would have run down the side of the tree (the depicted piece would be properly-oriented if rotated 90˚).© Kaegen Lau

Rough amber from an old site near Coalmont, British Columbia. The original site is now closed to collecting, since a mining company somehow got a court injunction and has "jumped" the owner's legal, active long-standing claim. The claim owner has informed me that he is not able to collect larger specimens (>3g fraction), as he had been able to in the past.© Kaegen Lau

Small (5-8g) partial nodules of raw blue amber from the east flank of the Bukit Barisan range of West Sumatra. These pieces are clear as glass, and fluoresce very nicely under a 140 lm LED light. *This Sumatra material (and Indonesian amber in general) is believed to have been produced by a parent tree belonging to the Dipterocarpaceae family; it's spectroscopic signature is also incredibly similar to Bitterfeld amber (also produced by a dipterocarp source tree). **This blue amber's particular locality is part of the Sinamar Fm., and the layers containing the resin are dated to be approximat© Kaegen Lau

83.8g raw amber mined from the Rivne region in Ukraine. The "eye hole" was likely formed when the organic matter (i.e., tree branch) the resin encased, was likely dissolved/washed away during the resin's diagenesis and redeposition (Baltic and most Rovno material is generally believed to have been redeposited).© Kaegen Lau
