The UV spectre of sun rays is invisible by the naked eye. Uniqueness of Blue Amber is in that UV is completely absorbed and does not penetrate or pass through the amber (this phenomenon is called the Usambara Effect).
So blue amber «catches the sun». I.e. what is normally invisible - becomes visible. You effectively see the sun on your own hand, chest and ears.
Rarity of this set is in combination of wonderful grape-like transparency, "champaign" effect inclusions (also called «full snowfall») and magnificent deepest blue surface hue. Amazing deep blue hue seen under normal light and eye-catching on sunset or under the direct sunlight. The blue reflections caused by natural sulphur inclusions are extraordinary: when you look at it (reflecting light) it appears blue, but when through it - displays various hues and here "full snowfall" or "champaign" effect - very rare.
The Blue Amber cabochons were carved from the raw material hand-picked by myself from the old stocks. As a raw material - this Blue to multicolour Amber is no longer available (Sumatra coal mines of Bukit Burisan mountain range where sourced - exhausted in 2015 - check it online).
Gold work and personalised design craft ordered on special commission to the renowned goldsmiths of Celuk village, Bali - no other set exactly like it exists or would exist. See our Catawiki feedback from the buyers of our deep Blue Amber.
No flash or filters used when taking pix. UV light test pix included, amber passed salt water test before putting in solid silver. Pics taken in various times of day to show the natural play of colours.
Solid gold is 14k hallmarked in Celuk and chemically/acid tested afterwards for authenticity.
Please take a note: highly skilled craftsmanship required for the high water pressure/bore polishing/carving of this material with no flaws or flakes. Approx. 80%-90% of material must get wasted to produce one cabochon. I.e. for the cabochon of 10-12 grams in weight - approx. 100 grams of Blue Amber required.
US Gemological Institute of America’ study revealed the deep Blue colour surface hue of the Sumatran Amber is the result of it's surface fluorescence stimulated by UV light. Study of the origins concluded Sumatran blue were produced by the extinct tree species Hymenaea Protera 20 to 40 million years ago
