I would be careful and use a reputable guide to show you where to get gems

I think every Monday and holidays are closed.

Hmmm not exactly sure but I think about 10:30 each day. Definitely closes at 5pm. Try google

Out of my experience I would say, it will be closed as most of the city/daily life gets to standstill during Thingyan. It's the same in the city, where almost ALL shops are closed. But this answer is not 100% updated. . .

I do not think so. The Market is well under a roof.

There are ATMs in the market

Oui mais je recommande de prendre son temps, visiter plusieurs vendeurs pour faire sa propre estimation et systematiquement demander une réduction (discount). Pour la région, les prix sont intéressants et la qualité des produits bonne.

The market will close from 12 April till 18 April 2016.

Hi! Yes, Myanmar does sell real genuine local rubies including other gems :) Myanmar is well known for the quality and price of the gems! As the market for gems is now booming, many unethical people will try to earn quick bucks out of you by selling you fake goods. A few way I know of to identify the quality ones from the fake ones are: 1. Check out their return policy. // normally the shops selling you genuine gems will offer reasonable and good return policies. The fake ones dont normally offer good return policy. 2. Ask for certificate of authenticity.// You should ask for this even though a fake copy could be made, its just an extra mile to make sure 3. Check the gem itself.// -Fake gems have scissor cuts and glass gems have rounded edges on cuts. -Genuine gems are lighter than the fake ones (this is because chemicals are added to make it seem more realistic). -Fake gems have more sparkle than real gemstones and there is a possibility that fake gems could either be a glass stone or a lab-created stone which glass gems might have tiny bubbles inside or scratches on it buy hardly flaws could be seen in lab-created stones are covered up. -A fake gemstone will have uneven colour as it could be possible that the stone was dyed to hide flaws. -Pressed or molded glass beads may have visible seam lines. 4. It is said that you can put it in your mouth to check but I think that's really gross..... hahaha so let's cancel out 4???// "An old test was to put the piece in the mouth. Glass will soon feel warm. Gemstones feel icy for a lot longer because they have higher thermal conductivity than glass. They take heat from your mouth so they themselves feel cold." - taken off the net of beadinggem. I learnt the above from the net so you can actually simply google " differentiating fake and real gems " and a list of useful links should appear :) I hope what I have shared helps! x
