From the French for 'a thousand grains', the tiny beads of a milgrain accent can add complexity and detail to a Ruby design, as well as create a vintage or antique look. Ruby is known as the gem of courage. Wearing a ruby pendant can help you get through the trials and tribulations of life. Yellow gold brings out the bronze and golden colors inside a smoky quartz pendant. White gold will highlight the brown and grey tones of the gem. Either way, you can't go wrong.
