British designer Stephen Webster (www.stephenwebster.com) uses the latest laser-cutting techniques to perfect his collection, including the Crystal Haze Classic white-gold bracelet with turquoise and diamonds ($17,000). Theo Fennell, the eccentric creator of silver Heinz ketchup and Smirnoff bottles (theofennell.com), shows he is about more than gimmickry with his delicate Cradle range of rings in 18-karat white gold. From the marquise aquamarine to the mint-green octagon tourmaline model (both from $12,000), his creations are redolent of summer.
