Silver Sky Imports sells variety of Crystal Singing Bowls. If you are collecting those stuff then you are lucky that you came across my blog.

Anyway, what is Singing Bowl?Most people use bowls for Buddhist spiritual meditation or to create a great art or conversation piece. Hand-made in a wonderful combination of 7 different metals which create 7 different distinct tones. These seven metals correspond with each of the planets, gold for the Sun, silver for the Moon, mercury for well, Mercury, copper for Venus, iron for Mars, tin for Jupiter, and lead for Saturn. Since the Tibetan singing bowls have a very mysterious history in them. It is sometimes hard to find information about them,and there is literally no mention of them in the Tibetan Buddhist canon
