Anything worn by Madonna and Sarah Jessica Parker gains instant cachet. Pieces by Bali-based designer John Hardy have adorned both women and his new cocktail Lavafire ring collection is sure to satisfy their followers. Inspired by the colours of an erupting volcano, look for stones - including topaz, aquamarine, garnet, citrine, pink tourmaline and amethyst - set in seven unusual colour combinations in sterling silver. The inner band of each handmade piece is engraved with a design depicting an erupting volcano. For a feminine look, slip on the Silver Kali Lava Berry ring set with pink tourmaline and rhodolite (below; HK$13,000). Or, opt for the Silver Kali Black Sapphire ring for a tougher style (HK$8,500). The collection is available at Lane Crawford, IFC Mall, Central, tel: 2118 3388.
