Thoughts will turn to romance when the fine jewellery and jadeite collection at Bonhams Autumn Auction goes on display. Nothing says love like a cluster of diamonds or a classic sapphire, and lasting symbols of true romance will be on offer in many hues and forms. Among the highlights of the 220 lots are a stunning 55.29ct necklace with 49 heart-shaped diamonds (HK$2,540,000 - HK$2,800,000) and a beautiful 36.83ct unheated Sri Lankan sapphire ring enhanced by an intricate diamond surround. Other pieces feature dazzling rubies, rare unheated Burmese sapphires, and fine translucent jadeite. Each is exquisite and will stand forever as a heartfelt token of love and devotion. Similarly attractive is the range of vintage timepieces and modern wrist watches going under the hammer. Collectors and connoisseurs can bid for limited editions of modern designs by some of the world's best regarded names, as well as for classic favourites with special rarity value. Of the 15 Patek Philippe watches on offer, one is an 18k rose gold perpetual calendar chronograph, with an estimated sale price of HK$1 million to HK$1.3 million. Another exceptional timepiece is a ladies' Piaget Limelight with more than 9 carats of sparking colourless diamonds set on 18k white gold (HK$250,000-HK$350,000). The auction will also feature fine clocks and pocket watches from different eras.
