Summer high jewelry season is underway, with major houses including De Beers, Dior, Tiffany & Co., and John Hardy launching new collections that blend heritage craftsmanship with fresh design. For overseas jewelry buyers, these releases signal evolving trends in diamond settings, colored gemstone use, and stacking jewelry, offering sourcing inspiration for bridal, fashion, and everyday lines.
De Beers refreshes Lotus collection with four-petal designs
De Beers London has reimagined its signature Lotus collection, first launched in 2009. The new range features a four-petal motif across rings, earrings, and necklaces, set with round brilliant diamonds in white or rose gold. A new thin cuff has been introduced, designed for stacking. To mark the launch, De Beers hosted an intimate dinner at Café Zaffri at The Twenty Two New York in early June, attended by guests wearing the latest Lotus pieces.
Diorissima collection debuts in Venice with 141 whimsical pieces
Dior unveiled its Diorissima high jewelry collection at the Venice Biennale, created by artistic director Victoire de Castellane. The line draws on symbols of happiness—sun, moon, stars, clouds, flora, fauna, and sea life—inspired by Monsieur Dior’s favorite artists. The first chapter includes 112 designs, from shoulder-duster earrings to transformable brooches, using bright lacquer and one-of-a-kind stones. Highlights include the Récif Fleuri brooch and the Galon Fleuri ring featuring a nearly 16-carat black opal surrounded by sapphires, emeralds, tsavorite garnets, and turquoise.
Tiffany & Co. expands Sixteen Stone collection with solitaire ring
Tiffany & Co. has added a Sixteen Stone solitaire diamond ring to its iconic collection, originally created by Jean Schlumberger in 1959. The new design features a center stone in X-shaped prongs with cross-stitch-inspired details in 18K yellow gold. The campaign stars Natalie Portman. Tiffany also introduced all-metal Sixteen Stone rings and other additions, broadening the line from high-jewelry statements to everyday wear.
John Hardy launches Ocean Heishi with ethically sourced quartzite
John Hardy has expanded its Heishi collection with the Ocean Heishi line, inspired by ancient bead-making from natural materials. The collection includes 4mm and 9mm bracelets and a 9mm necklace, using ethically sourced multicolor quartzite in aquamarine, lapis, and amber hues. Each piece is unique due to natural stone variations, and is available with sterling silver or gold accents.
What buyers should watch
These launches highlight key trends for sourcing: stacking-friendly designs (De Beers cuff), colored gemstone diversity (Dior and John Hardy), and heritage-inspired solitaires (Tiffany). The use of ethically sourced materials and one-of-a-kind stones aligns with growing buyer demand for traceability and uniqueness. Suppliers should monitor demand for multicolor quartzite, black opal, and mixed-gemstone settings, as well as the continued popularity of rose gold and yellow gold finishes in bridal and fashion categories.
