Boucheron has unveiled its new Histoire de Style, Art Déco high jewellery collection, which has been designed by creative director and visionary jeweller Claire Choisne. For the diamond-drenched line, Choisne delved into the French house’s abundant art deco archives and championed a profusion of niche techniques and materials. But it’s her Plastron Émeraudes necklace that steals the show.

Whisper-thin strands of white gold and platinum are set with 220 emerald beads that weigh a jaw-dropping 1,071.97 carats. They are secured in place by black lacquer and onyx that’s mounted with diamonds. This piece can be worn three ways and can be transformed from a long necklace into a tight choker that cinches at the collarbone, as well as a comfortable bracelet. The most expensive piece from Histoire de Style, Art Déco, this necklace will set you back over US$4 million.

Bronze-tinted sculptural pieces from the brand-new Muse collection by Forms wrap about the wrist in unique ways. Slender silhouettes made using mixed-metal designs can be layered, piled and put together so you’re ready for any occasion. Choose one with a centrestone that’s fuchsia-pink or cherry-red for extra oomph.

Hong Kong-based brand Weekdays and Weekends, which also goes by “5 + 2”, has been inspired by the Chinese art of feng shui. The company has unveiled several yin-and-yang-styled creations that have been made using white gold. Our favourite piece is the Feng Shui pendant, which features a standout lab-grown yellow diamond that weighs 3.8 carats.

Based in Los Angeles, sisters Yarden and Oren Katz are the third-generation jewellers behind Carbon and Hyde, which creates fine jewellery that’ll stay fashionable all year. The duo experiment with unconventional shapes and textures, and we particularly love their latest must-have necklace. Retro-looking links handcrafted in yellow gold are fastened with an easy-to-wear clasp, making this accessory wearable and well-suited to modern women everywhere.

This collegiate-style signet ring is sure to be a stunning addition to anyone’s jewellery collection. Named after the 18th-century botanist and explorer Jeanne Baret, the first woman to have travelled all the way around the world, this sparkler is by Singapore-based fine jewellery brand State Property.

South Sea pearls have always been celebrated by Jewelmer and now the latest brooch offered by the brand, La Mer en Majesté Ocean Gift, is inspired by the play of light on the ocean. Five golden pearls are set onto writhing, coral-like structures that are further elevated by dazzling white diamonds.

Founded in 2013 by Mollie Faith Good and Stephanie Walters Abramow, Walters Faith boasts pieces that embrace boldness and femininity. These rose gold hoop earrings have glittering edges lined with 2.9-carats’ worth of white diamonds for added sparkle.

Victoire de Castellane, creative director of Dior Joaillerie, has designed a cutting-edge selection of watches and jewellery that's set with colourful enamel and ornamental stones. Flexible bracelets and slanted cuff openings ensure each piece is incredibly easy to wear, while misshapen dials and asymmetrical structures add a playful, unexpected and surprising twist that's oh-so Dior. Bravo, Victoire. 

Precision, high design and allure come together in the form of De Beers’ new collection, Reflections of Nature, which is made up of five spectacular sets. Not only does this high jewellery line push the boundaries of craftsmanship and technical know how, but it takes inspiration from five countries in which De Beers diamonds are mined.

The Landers Radiance necklace is worth an eye-watering US$650,000. Various golds are combined and set with rough and polished diamonds that weigh a total of 86.6 carats. Subtle shades of orange, green, grey and pink are arranged to resemble the colourful coral and tropical fish found in South Africa.

Tiffany & Co has announced that it has acquired an exceptional D-colour, oval-cut diamond that surpasses 80 carats. Responsibly sourced in Botswana, the stone will be set into a necklace inspired by an archival high-jewellery necklace that premiered at the 1939 World’s Fair. The finished piece will be showcased in 2022 to celebrate the brand’s fully renovated Fifth Avenue flagship in New York City, and is expected to be the most expensive diamond ever offered by the jewellery house, next to the famous 128.54-carat Tiffany Diamond worn by Lady Gaga at the 2019 Oscars.

New York-based jeweller Vedantti finds inspiration in organic forms, which the brand infuses with an elegance and softness that’s difficult to resist.

Venyx creates fine jewellery for modern women who appreciate classic luxury. This yellow gold and diamond-set necklace will never go out of style and makes a great gift for a significant other.

The new Lucky Spring collection by Van Cleef & Arpels celebrates the arrival of spring. Fashioned in mirror-polished rose gold, the line features elegant touches of mother-of-pearl, carnelian and onyx, carefully arranged to capture plum blossoms and ladybirds, which are depicted both resting and mid-flight.

London-based, Ghana-raised jeweller Emefa Cole is known for her traditional wax-casting techniques that create layers of gold, silver, rhodium and oxidized bronze. Just last year, the Victoria and Albert Museum added Cole’s Vulcan Series ring to its permanent collection, after the piece was noticed at an independent craft fair. Minimal and moody, designs are set with recycled gold as well as vibrant coloured gemstones mined in Africa.
