This is an authentic Burmese Amber Gemstone, 98.8 million years old. This specimen has been examined by paleo entomologists at the American Museum of Natural History in New York City.
Amber from northern Myanmar has been commercially exploited for millennia, and it also preserves the most diverse palaeobiota among the worlds' seven major deposits of Cretaceous amber. Recent estimated ages vary from Albian to Cenomanian, based on palynology, an ammonoid, and Mesozoic insect taxa preserved within the amber. The burmite-bearing rock is sedimentary and consists mainly of rounded lithic clasts (0.03 ∼ 0.15 mm in diameter), with minor fragments of quartz and feldspar. Among the lithic clasts are mostly volcanic rocks. Zircons separated from the amber matrix form two groups: Group-I zircons are overgrown and have variable CL patterns, experienced slight geological disturbances after they formed, and their Ion microprobe 206Pb/238U ages fall into a very narrow range of ∼102 Ma–∼108 Ma; Group-II zircons are typical magmatic ones with rhythmically flat zones, inferred to be derived from volcanic rock clasts, and yielded a concordia 206Pb/238U age of 98.79 ± 0.62 Ma. The dating on Group-I zircons is only for their interiors, thus hiding what age excursion might come from the overgrowth. Considering the nearshore marine environment and 1-m thickness of the burmite-bearing sediments, and the syn- and post-eruption deposition of volcanic clasts, the age of 98.79 ± 0.62 Ma therefore can be used as a maximum limit for the burmite (either at or after), establishing an earliest Cenomanian age for the fossilized inclusions. The age also indicates that volcanic eruption occurred at 98.79 ± 0.62 Ma in the vicinity of the Hukawng Valley.
Burmese Amber or Burmite
Burmese Amber (Burmite) from northern Myanmar, called Burmese amber or merely “burmite”, is the only Cretaceous amber deposit in the world that is exploited commercially, as well as the first to have been studied scientifically. The history of its use has been reviewedby Zherikhin and Ross (2000), Grimaldi et al. (2002), Cruickshank and Ko (2003), and Ross et al. (2010). Briefly, burmite had been used primarily in carvings for at least two millennia by Chinese people, for which the material is ideally suited (Grimaldi, 1996).
The deposits in the Kachin state, northern Myanmar, are productive (an estimated 83 tons were exported between 1898 and 1940), and some amber pieces are very large (the largest is 15 kg, in the Natural History Museum, London). Moreover, colours vary from
a transparent yellow to a highly desirable deep red (Figs. 1e3), the amber resists fracturing and is relatively hard (1.2 times harder than Baltic amber), and it receives a glassy polish. Burmite mining lapsed from just before the independence of Burma from Britain in
1947, and did not resume until the late 1990s. The greatest value of burmite, however, is scientific.

We have been collecting amber in the field and prepping rough fossil amber specimens since 1993. Photographs of our specimens have appeared in National Geographic, Nature, Science, Scientific American, Discover, Time, Newsweek, The New York Times and others. We have been featured in PaleoWorld's The Amber Hunters. We offer authentic museum quality Dominican Amber display specimens of rare insects in amber and also authentic rare Dominican rough unprepared amber for sale. Our collections include museum quality rare insects in amber, unusual botanicals and flowers in amber and also rough unprepared Dominican Amber gemstones. We have traveled many times to the Dominican Republic where we have chiseled beautiful amber gemstones out of the lignite layers deep in the amber mines north of Santiago. We have excavated in the Palo Quemado and Los CaCaos blue amber mines and also in La Nueva Toca and the world famous La Toca amber mines way up in the mountains north of Santiago. For many years we have extensively collected mid Cretaceous New Jersey amber in the Raritan formation of central New Jersey and have traveled many times to collect late Cretaceous and early Paleocene amber in the Hanna formation of eastern Wyoming. We have collected mid Cretaceous amber in the Black Creek formation of eastern North Carolina and we have spent weeks collecting mid Cretaceous amber in the northern most Tundra of Alaska. Some of our most recent collecting trips have been in October of 2003 to the western Aleutian Islands some 1000 miles west of Anchorage to explore and collect Miocene amber, August of 2004 and April of 2006 we were back in the Dominican Republic to collect Miocene amber from the Palo Quemado amber mines which have recently closed due to the miners finding little amber, we were back to the Dominican Republic in April of 2006 to video in the La Toca amber mines, and most recently in August of 2007 we excavated in La Toca and La Bucara. As these specimens are examined and prepared we will post some additional photos of this new locality. We've done excavations in the Dominican Republic in 2012, 2014, and 2016. Recently we have just returned from 2 collecting trips to a Eocene amber deposit in the south in 2017.
We have donated many hundreds of amber specimens to museums in the United States and have several dozen new species of insects in amber named after us. We have examined several thousand specimens of rough Burmese amber and have prepped many new Burmese fossil amber specimens. We have traveled to Europe with colleagues to examine unusual spectacular Dominican Amber specimens in private collections and we consider the amber curators of the museums in Santo Domingo, Puerto Plata and New York City our friends. Exploring for and collecting amber along with the examination and research of amber is our passion.
