For the collection, the maison’s artisans drew notes from Cartier's heritage in jewellery making and melded them with those they had extracted from the world of astronomy.

The materials used in the jewellery, like celestial bodies, collide to result in a bold formation—one where precious and semi-precious stones meet and become unexpected best friends. Think diamonds and rutilated quartz, or emerald and rock crystal.

To match their out-of-this-world designs, the names of the pieces also take after matters of outer space, such as Aphélie, which means the point of the orbit at which the Earth is furthest from the sun.

Following the exhibition, a gala dinner rolled out at the history-rich Shoreditch Town Hall in East London. English actresses and International Cartier Friends of the Maison the likes of Claire Foy, Lily Collins and Letitia Wright were present to celebrate the launch that evening with Cartier CEO and president Cyrille Vigneron, as well as relish a high-octane performance by the exuberant Beth Ditto and her rock band.

The Théia necklace, which was first worn by English actress Lily Collins to this year’s Met Gala, is defined by a stunning ensemble of seven round-shaped Colombian emeralds surrounded and accompanied by rock crystal. Bearing an art deco style, it also features diamonds and onyx which give it a classic yet graphic beauty. And showcasing the maison’s penchant to create versatile pieces, the pendants at the front and back of this necklace can be removed and worn as a brooch or on a chain by itself.    

Another art deco-esque piece is this pink-gold Aphélie necklace, which features a golden-brown rutilated quartz heart that seemingly emits rays of pink diamonds, coral, morganite and onyx.

This piece from the Soreli range is centred around a striking cabochon-cut rutilated quartz, which glimmers to life as light passes through its translucent body. Fun fact: the stone actually hides a watch dial underneath, which is only seen when one pushes a tiny button to open the cover. On the bracelet, kite-shaped and brilliant-cut white diamonds are arranged to form a geometrical motif. 

With this Équinoxe necklace (named after the equinox, which is the instant of time when day and night are of equal length), lapis lazuli represents the deep blue night sky, while diamonds in yellow, orange and white resemble a constellation of stars. The brightest star here is represented by a sizeable orange-toned yellow sapphire placed right at the heart of the piece.   

Speaking of stars, Cartier illustrates the radiance of the sun in the Yuma necklace. Diamonds ranging from golden yellow to brown in different cuts are contrasted with platinum. Depending on the occasion, the necklace’s length can be adjusted according to one’s fancy.

Last but not least is the Zemia range, which loosely translates as Earth and bears similar colours found naturally on the planet. Here, the Zemia bracelet is strikingly ornamental thanks to a 77.27 carat matrix opal from Australia which is paired with a vibrant combination of blue and purple sapphire, garnets and diamonds.
