Is this a full diamond tennis bracelet?

No. It is a station bracelet: diamonds are set at intervals along the gold, not edge to edge. A true diamond tennis bracelet carries far more carat weight and continuous sparkle.

What quality are the diamonds?

Roberto Coin states it uses only full-cut diamonds, with G/H color and SI clarity as the minimum grade. That is a solid mid-to-upper range for fine jewelry.

What is the hidden ruby?

A small ruby is set on the back of the piece, a Roberto Coin signature meant as a wish for health, happiness and longevity. It is not visible when worn.

Will a 7-inch bracelet fit me?

Seven inches is a common women's bracelet length and fits most average wrists with a little drape. Measure your wrist and add about half an inch for comfort before deciding.

Station bracelets are hard to resize because the diamond spacing is fixed. Removing links would break the pattern, so treat the 7-inch length as final.

How should I care for it?

Store it separately to avoid scratches, clean with mild soap and a soft brush, and have a jeweler check the prong settings once a year. White gold may need rhodium re-plating over time.
