See how the 'points' look ragged? This is a major sign that these were made in India. They are made by assembling wedge shaped strips of glass. The result is imperfect points where the design fails to line up.

The Venetian method is to mold the molten glass cane prior to dipping new glass layers. There might be bending or rounding of the tips, but they will have single points, not the raggedy look of your chevrons from India.
