This is the brand’s fourth high jewelry collection and Gucci is celebrating it by unveiling it Wednesday at Palazzo Settimanni, the brand’s historical archive in Florence. Gucci relies on an atelier of around 40 people and production is split between Milan and Valenza Po, a major goldsmith hub in Italy, with an exclusive partner.

The gems, more than 200, are increasingly central, and color is key to the collection.

The light-hearted spirit of spring is telegraphed by the blooming pattern of Gucci’s signature Flora motif. A stunning cushion-cut 226-carat green tourmaline rests in carefully crafted openwork metal, punctuated by star motifs and diamond baguettes. Multicolored tourmalines and diamonds stand on the necklace’s chain.

A necklace with a 161-carat cushion-cut pink tourmaline is encircled by multiple levels of diamonds and colored enamel, all set on a chain sparkling with 72 88-carat tourmalines, which create a chromatic degradé.

More saturated hues reflect the warmth of summer through emeralds, spinels and Paraiba tourmalines, sprinkled with multifaceted diamonds. Sophisticated constructions, daring cuts, such as the fan cut, point to Gucci’s craftsmanship.

Muted and soft tones are representative of fall in silky stones such as yellow sapphire, pink tourmaline and mandarin garnet. A 78-carat yellow sapphire necklace is surrounded by an array of tourmalines and diamonds, while a vintage-style yellow gold bracelet is set with five mandarin garnets cut into three different shapes.

Embracing a more wintry mood, an enamel and diamond necklace stands out, defined by a milky, iridescent 92-carat opal.

Gucci is unveiling one-of-a-kind European-cut antique diamonds and stones that add a touch of vintage to the collection. Created primarily from 1890 to 1930, European cuts characterized the Art Deco period.

Fan, briolette, paisley and kite shapes all feature, as speckles of baguette diamonds add an additional touch of light.

A pair of jacket earrings are designed around two fan-shaped emeralds totaling 18 carats, cascading with a mesh of diamonds and tourmalines. There are also new hair accessories and detachable pieces that can be worn in different ways.
