Autumn is here, and this gorgeous bouquet of jewellery is sure to inspire some spirited accessorising for the season.

Tiffany & Co.

This bracelet (above, price available upon request) from the most recent Blue Book Collection from Tiffany & Co. is layered with fine, palm-like fronds, each covered in bright green tsavorites and yellow sapphires — it would be perfectly paired with a colourful, tropical-print dress at a springtime fête.

Suzanne Syz

They might be called the "Heartbreaker" earrings (price upon request), but we've got nothing but love for this exquisite Suzanne Syz creation — a dazzling cascade of hand-carved peridot leaves hang from two mandarin garnets, their subtle movement calls to mind a cool springtime breeze.

It's part of Hardy's Cinta collection — the Balinese word for "love." (johnhardy.com)

Each design from Roberto Coin's Garden Collection captures a dynamic springtime moment. This ring, $US29,000 (about $A38,040); available by special order) highlights a luscious morganite stone surrounded by a menagerie of garden creatures, from golden caterpillars and black spinel-studded butterflies to amethyst-dotted berries.
