A single line of pear-cut blue topaz runs around this tennis bracelet, and every stone points the same way, the tip of one pear leading into the rounded end of the next, so the row reads like a string of falling drops. Each pear sits in its own slim frame of gold-plated silver, held by small prongs at the tip and sides and joined to its neighbor by a tiny link. That makes it a pear tennis bracelet that bends link by link and follows the curve of the wrist.

The blue is even and clear from one stone to the next, without a rainbow sheen and without changing between daylight and lamp light. Yellow gold plating frames each stone, so this is a blue topaz bracelet in a warm gold tone rather than in white metal, and the two colors keep each other bright. As in an eternity bracelet, the stones carry on all the way round, stopping only at the clasp.

The stones are synthetic blue topaz, grown rather than mined, and faceted as small pears of 4 × 3 mm, which keeps this gemstone tennis bracelet narrow on the wrist. Topaz is the November birthstone, and blue topaz is also listed for December, so this topaz birthstone bracelet suits a birthday in either month.

We cast the bracelet in 925 sterling silver in our workshop, finish it by hand, polish it and plate it in gold. With stones this small it weighs about 4.6 grams: a gold-plated tennis bracelet thin enough to wear every day and to stack with fine chains or a watch.

It measures 20 cm, about 8 inches, and closes with a lobster clasp. A short extender chain beside the clasp makes it an adjustable tennis bracelet, since the clasp can catch any of its links. This classic tennis bracelet for women is a simple gift for her: one color of stone, one color of metal, and a shape that has been worn for decades.
