Ruby_part_5

I reloaded this video (14-08-11) using different setting to export it. Hop it will work better...
Here is the part 5 where I show macro photography and imitation, treaded rubies, synthetic rubies inclusions, glass past. I finish with posting few pictures of natural stones that could be used for ruby simulant and their prices and some pictures of natural rubies no treated with their price on the retail market.
