● 2x Sumatra‑amber (Glessite) – approx. 125 carats total – blue fluorescence – scientifically documented (Warsaw 2014)

Note in advance: Through complete scientific documentation and the unequivocal assignment to a tested batch, the buyer receives two clearly identifiable, rare, collectible individual pieces, which, in this form, are relatively rarely seen on the market.

● Description:

Offered are two extraordinary pieces of Sumatra amber (Glessite) with a total weight of about 25 g (≈ 125 carats) and an impressive size of each around 4 × 3 cm. The pieces show blue fluorescence under UV light – a rare natural authenticity feature that occurs only in a small portion of the fossil resins from the Neogene strata of Sumatran Miocene.

Under normal light, clearly discernible structures of fossil wood are also visible. These textures are typical for resins of the tree family Dipterocarpaceae, from whose fossil resins Sumatra amber was formed millions of years ago.

These rarer specimens originate from a batch that was scientifically studied in 2014 in Warsaw (Poland). The analysis was conducted at the Polish Academy of Sciences – Museum of the Earth in Warsaw, one of the world's leading institutions for the study of fossil resins. The examination was performed using infrared spectroscopy (IRS) – the internationally recognized standard method for the unequivocal identification of fossil resins.

The analysis was conducted by Prof. Dr. hab. Barbara Kosmowska‑Ceranowicz, one of the most renowned amber experts worldwide and a long-standing specialist of the International Amber Association. The IRS spectra unequivocally confirmed that the examined samples came from the same batch:

• from Neogene strata (approx. 20–40 million years old)

• formed from fossil resin of the Dipterocarpaceae

• clearly assignable to the Glessit group

The scientific inspection report will be provided to the buyer in paper form as an authentic quality certificate. This report documents origin, age, botanical assignment, and the scientific methodology used.

The additional transmission photos in the gallery reveal deep red and orange regions as well as the glowing yellow zones of the fossil resin and show the internal structure of the Glessit in impressive clarity.

Besides the clear collector features, the exceptional material quality of these premium Glessits also opens up the possibility of professional further processing into very high‑end jewelry.

● Special features of this piece:

• Strong blue fluorescence – rare natural authenticity feature
• Glessit type – scientifically documented assignment to fossil resins of the Dipterocarpaceae
• Age: approx. 20–40 million years
• Clearly visible fossil wood structures
• 2 pieces with total approx. 125 carats and each 4 × 3 cm in size
• Scientifically documented batch (2014)
• Analysis conducted by one of the world’s leading amber experts
• Laboratory certificate included

● Origin & credibility:

The pieces come from the stock of an officially registered German dealer who has been active in the gemstone and fossil trade for many years. High customer satisfaction is demonstrably evidenced by numerous documented customer surveys. The batch from which these pieces originate was sampled and tested in a laboratory in Warsaw, thereby scientifically securing the authenticity of the entire shipment.

● Value & rarity:

Blue-fluorescent Sumatra amber has been sought after for years due to its natural rarity and has already traded on the collector market at significantly higher prices than ordinary Sumatra amber without fluorescence.

● Conclusion:

Sumatra amber with blue fluorescence, visible wood structure, scientific documentation, collectible size, and about 125 carats weight are extremely rare on the market. The combination of:

• Size (approx. 4 × 3 cm)

• Weight (≈ approx. 125 carats)

• Blue fluorescence

• Glessit type

• scientific analysis

• proven provenance

makes these pieces comparatively rare collector objects that stand out clearly from typical raw material.
