The new interest in this collecting, mainly from Russians, made it possible to describe two new ants in 1996 and 15 other bugs in 2000. This was followed by a continuous edition of paper that described new types from the US and London collections. Over the past few years, Chinese interest in Myanmar has grown and many new deposits have opened up in Myanmar to meet market demands.
As a result, this type of bird is now easily accessible and many researchers around the globe are investigating its pockets. There has been a surge in the number of new research projects that describe new types. You can find a complete listing of all types in Burma Bernstein here. Most of these were exhibited in the 2013 Amazon Rainbow Show.
Some of the new varieties have been identified from this compilation and are shown here.
Identification of springs among Burma's jewels
Summary: There are two main wells of ruby in Myanmar (Burma)--Mogok (Mandalay Division) and Mongshu (southern Shan State) - and several smaller springs Nawarat/Pyinlon (near Namkhan, Shan State); Tanai and Nayaseik (Kachin State); Katpana (Kachin State); and Sagyin and Yatkanzin stoneware treaties (Madaya Community) near Mandalay. The mogok and the smaller occurrences are also in pure marmor with a great variety of jewels from each wing and close resemblances between the two.
Mongshu, although associated with Metasedimenten and Murmeln, result clearly different roughened and processed rocks. The Mongshu rocks are easy to distinguish from those from Mogok and the smaller mines. Fundamental properties of the smaller springs are described, but further research is needed to evaluate the criterions for the distinction between these and Mogok.
Hundreds of roubles from these springs in Myanmar were investigated for characteristics that could normally be photographed with a Mark 6 Gemolite with a 10X ocular at maximal enlargement (~60x). Mogok' classical ruby contains typically small, delicate rutil pins - so-called satin. Clouding occurs either as a total haze, in spots or in different zones.
In general, long, slim rutilated pins in net-like designs are more often in pink and reddish ruby. Böhmit-pins are limited to double planers and other lamellas in ruby. Other most commonly included in mogok ruins are colourless calcite yolomite (sometimes yellowish) - both show inner twins and/or cleft surfaces - price volatile avatite, spathic, pyrrhotite, titaniumite, magnetized, micas, spinel and possibly tourmalin, diopsid and many other mines.
Inclusion of fluids in the case of broken springs (healing feathers) are also characteristic characteristics of Mogok-Rubins. The Mogok ruby is known for its intensive "pigeon blood" colour, intensified by natural light fluorescent, but its satiation reaches to rose. Distinct crystallographical colour zonation is uncommon, but slight bands and small "vortices" of colour zonation, known as syrup, are the custom.
Pyinlon stones on the Nawarat rock wing are found in a crystal like Mogok. The entrapment mineral in these robinies is dominant in calcareous, dolomitic and ruby with less avatite, and probably phyrrhotite and spinel. 2. It tends to be less marked (thinner or dustier) than Mogok ruins.
Self-adhesive banderoling is not unusual, but colour banderoling, if present, is not pronounced. Nawarat crown is 5. 45 carats ruddy with an extraordinarily delicate blood-red colour, but the most of the rudiments have a middle colour with a slight violet hue. Nayaseik and Tanai are located in Kachin State in the north of Burma.
They seldom have silks or plumes and are usually very translucent. Incorporations are frequent, dominant of Calcite, Dolomit, Apatite and Mikas as euhedrale to subedrale granules with pronounced faces. Very-small, pronounced roughage particles were seen. Pink and reddish colours are characteristic; very few of the precious dark ruby have been found.
In the Sagyin stony wing jewels were extracted from colluviae sediments which were eroded from granite during the rule of King Thibaw (1878-1886). The colour ranges from pink to middle reds, although some rocks of intensive dark reds have been recorded. The rocks are relatively free of silt, but can contain dust sediments of debris and clear calcitic pockets of sub-hedral to round shape.
Catpana ruins vary from purple-pink to pink-red, less desired colours in Myanmar. Densely woven silks are usual and result in many delicate ruins, so that the fabric is usually used as cabochon or as small earring beads. The Mongshu ruby is characterised by a centre blue-violet nucleus in intensive scarlet crystal, curative plumes, several pronounced growing zone pattern and very thin crystalline pins on inclusion in non-treated rocks (Peretti et al. 1995).
Mogok ruins are less frequently found in translucent calcitic pockets and thick areas of satin. Almost all Mongshu materials are heat-treated to eliminate the blue or purple hue and thereby enhance the colour of the skull. In Myanmar, topical treatment includes a temperature of 700-1200ºC, probably without the use of solder, which is not sufficient to make fluxed springs in fissures.
Soft, veil-like liquid trapping springs or "fingerprints", dissolved vibrating pins and snowflake-like fines are some of the diagnosis characteristics of the rocks used. Cometary stringer silks, as seen in Kashan synthesis ruby, were found in Mongshu ruby treatments. Dissolved granules of broken stone and white remedies create a blurred or "sleepy" look in polished stone.
Enclosures surrounded by disc-shaped tension springs and enclosures that are white or bubble-like with high reliefs are usual for heat-treated masonry. Hughes, R.W. (1997) Burma (Myanmar) 300-343.
