Glass bangles are mostly produced in only one Indian city called Firozabad in North India. Bangles that were made from plastic started replacing the glass bangles. Glass bangles are usually smooth, with some texture or set with stones.
However, in many cultures, especially in the Arabian Peninsula and in South Asia, bangles have evolved into various types in which different ones are used at different occasions. In India, Hyderabad has a historic market for bangles named the Laad Bazaar. In Pakistan, glass bangles are almost all produced in Hyderabad, Pakistan. Glass bangles are found in many colors.
A diamond is a form of carbon
A diamond is a form of carbon that was created deep within the core of the earth more than 3 billion years ago and brought to the surface by volcanic eruption. In diamond, each carbon atom is bonded to four other carbon atoms in a tetrahedral structure, like a pyramid. Each link or bond is the same length, and the tetrahedral formation is therefore completely regular.
Theoretically a perfect diamond crystal could be composed of one giant molecule of carbon. After the magma cooled, it solidified into kimberlite, where the precious rough diamond is still found today. It is the strength and regularity of this bonding which makes diamond very hard, non-volatile and resistant to chemical attack.

And that has made them so highly prized throughout several centuries. Diamonds continue to hold a deep fascination. As the diamonds is world’s ultimate symbol of love.
