Vintage 14k Gold Onyx Diamond Round Pendant

About onyx jewelry Onyx is renowned for its striking appearance and unique properties. Formed through the slow crystallization of quartz in the presence of water, onyx belongs to the chalcedony family. The gem is often found in areas with volcanic activity. Jewelry designers are drawn to onyx for its classic elegance and deep, lustrous hues. Onyx is often used to add sophistication to any design. The stone’s smooth texture allows to capture the essence of refinement and luxury. Onyx was a perfect gem for the Art Deco era’s sleek lines and geometric shapes. Its smooth texture and bold black-and-white contrast perfectly complemented the era's streamlined aesthetic, particularly when paired with platinum. As a result, onyx became synonymous with the Art Deco movement, embodying its emphasis on modernity and geometric precision. Among contemporary jewelry makers, the gem finds frequent use in the pieces of all the big brands. Such collections as Perlée and Alhambra by Van Cleef & Arples are great examples of onyx’s application.
