Black onyx. Oval cut. A deep, uniform matte-to-polished black stone in a clean solitaire stud — one of the most versatile and enduring stone choices in jewelry.

These black onyx stud earrings feature an oval-cut black onyx stone in a minimal solitaire setting with a standard push-back post. Black onyx's defining characteristic is its deep, uniform black — a complete, saturated darkness with no banding, no translucency, and no surface variation when polished. In a solitaire stud, that uniform black sits against the earlobe as a clean, unambiguous dark shape: a simple oval of solid black that provides a grounding visual counterpoint to metals, skin tones, and clothing of any color. Available as a single earring or a pair, in 925 sterling silver, yellow gold plated, or rose gold plated. Handcrafted in Jaipur.

About Black Onyx

Onyx is a variety of chalcedony — a microcrystalline form of quartz — characterized by its banded structure. Natural onyx occurs in many color combinations, with the black-and-white banding of sardonyx being the most widely recognized natural variety. Black onyx as used in jewelry — the uniformly deep black stone familiar from signet rings, mourning jewelry, and minimalist contemporary pieces — is almost universally chalcedony or agate that has been treated (typically dyed and heated) to achieve a fully saturated, uniform black without the natural banding. This treatment has been standard practice in the onyx trade for centuries and is accepted and expected within the industry. The resulting stone is hardness 6.5–7 Mohs, takes a high polish, and has a deep, opaque black body that does not transmit light. Black onyx has one of the longest histories of any gemstone in jewelry: it was used in ancient Mesopotamian cylinder seals, ancient Egyptian amulets, Greek and Roman signet rings, and later became the dominant stone of Victorian mourning jewelry in the 19th century — a period that established much of the black gemstone aesthetic that persists in contemporary minimalist and gothic jewelry today.

Oval Cut for a Black Stone

The oval's smooth, continuous curved outline is particularly effective for a stone like black onyx, whose visual appeal is based entirely on its uniform color and surface quality rather than facet-generated light play. An oval cabochon (domed top surface) would maximize the stone's polish and depth; an oval faceted cut adds structure at the edges while keeping a large, visible table. Either way, the oval's symmetrical but non-circular outline creates a solitaire stud that is immediately readable as an intentional shape choice — more refined than a round, less angular than a square or cushion, and elongated enough to have a directional orientation on the earlobe that draws the eye slightly upward.

Styling Black Onyx Studs

Black onyx works equally well with yellow gold, rose gold, and silver settings, as its uniform black provides neutral contrast against all three metal tones. Yellow gold creates the most classical pairing — the warm metal against the cool black echoing centuries of signet ring and cameo tradition. Rose gold creates a softer, more contemporary contrast. Silver or white metal creates the starkest contrast — the coolest, most minimal pairing. The oval solitaire format also works as a unisex piece: the geometric simplicity and dark color palette are not gender-coded, and the oval's proportions sit proportionally on a wide range of earlobe sizes.

Care Instructions

• Remove before swimming, showering, or applying lotions and perfumes (especially for plated finishes)
• Onyx is 6.5–7 Mohs — durable for everyday earring wear; wipe gently with a soft, damp cloth
• Avoid prolonged exposure to harsh chemicals or ultrasonic cleaners
• Store in a padded box away from harder stones that could scratch the polished surface
