Blue is the colour of communication and self-expression. The clear, voluptuous colour of Blue Topaz certainly speaks for itself. From the pure pastel blue of an Alpine glacier, to the glow of the mid-summer sky, to the aquatic hue of the deepest ocean, refreshing Blue Topaz brings a breath of fresh air to contemporary jewellery designs.

The ancients prized Topaz as a stone of divinity that could dispel enchantments, detect poisons — even render the wearer invisible at will. Today it is claimed as the state gemstone of Texas.

Blue Topaz rivals Aquamarine in colour and charm. Found in greater abundance, it offers superb clarity and luminous colour at a fraction of the cost.
