7.5 x 8mm - Generally for younger women, 26 to 29 years This is our #1 best-selling size, and the last size in the lower bracket of more readily available sizes -- a jump to the next size, 8 x 8.5mm, more or less doubles the strand's price. It's really the only size one could call neither "too small" nor "too big." It's a staple of any woman's wardrobe; she can dress it up or dress it down. It's not too showy, and it very tastefully exudes an image of importance -- a classic for the upwardly mobile career woman. It also suits very well as a wedding-day gift or a wedding anniversary gift through the fifth year of marriage. This necklace features the American Pearl 18K yellow gold designer clasp. Also available in 18K white gold.
