Myanmas (ex Burma) is one of the most famous source for gemstones. Some of the most beautiful rubies comes from the famous Mogok Valley. But several extremely rare gems also come from Myanmar, as Hibonite or Poudretteite…
Poudretteite is one of the rarest gems on Esrth. The gem was first disacovered in Canada, but crystals were extremely small. In 2000 a pinkish gem is discovered in Mogok Valley. Ten more in 2004, and 30 more in 2007. It gives a good idea of the rarity of these gems. This crystal is terminated and has an exceptional clarity (flawless).
Johachidolite is an extremely rare gem from Mogok, Myanmar. Rarely found on the market, this specimen has a top color and is flawless.

Painite is a very rare borate mineral. First only one crystal was known at British Museum, then a new source was discovered in Myanmar and cristals various qualities were found. Faceted gems are extremely scarce (see link to article). The two sources are Ohngaing and Kyauk-Pyat-Thet villages, in Mogok valley. The color is a bit open but clarity is great.

Hibonite is one of the rarest among rare gems. If some opaque rough is found in Madagascar and Russia, the gem quality was found only in Tha-Yet-Pin-Pyint, west of Mogok, Myanmar, in 2011. Only a view stones had a gem-grade and it is estimated that only a dozen faceted gems exists, even probably a vew more exist now. This specimen has a honorable size and a very good clarity for the specie.

These small pinkish red rubies come from Burma. If 90% of all rubies are heated to improve color, that one is not heated. But more of that, it present an amazing color change, never seen in rubies. With cold light it becomes vivid purple. I is being tested with Raman spectroscopy.
The colorless grossular garnet or Leuco Garnet is the rarest of all garnets and an extremely rare gem. Like 99% this one display a very light yellowish color, otherwise a good clarity despite some beautiful negative crystals. It comes from Myanmar.
