Skye Kite® Black Onyx Stud Earrings in Sterling Silver

These are kite-cut black onyx stud earrings in 925 sterling silver — natural black onyx centers framed by marquise and round simulated diamond accents, in the same Skye Kite® design language as our matching engagement ring family. The deep, glassy black of onyx against bright silver makes these earrings read gothic, Art Deco, and dark academia all at once. A bestseller in our gemstone studs collection.

The Stones

• Natural black onyx, kite cut — 7.0 × 10.0 mm per stone
• Approximately 3 carats total weight for the pair
• Mohs 6.5–7 hardness — durable enough for daily wear with normal care
• A jet-black, opaque variety of chalcedony quartz with a smooth, glassy polish
• Sourced from natural deposits — Brazil, Madagascar, and India are the major sources

The Setting

• Marquise CZ + round CZ accents at the shoulders of each kite center stone — a fan-cluster arrangement that picks up light around the matte black onyx
• Four-prong basket holding the kite center, prongs at each point for full security
• Friction-back posts for everyday wear

The Metal

• 925 solid sterling silver — hallmarked, not plated
• Hypoallergenic and nickel-free — safe for sensitive ears
• Will not turn skin

Why Black Onyx (not black diamond)

Black onyx is a natural quartz variety prized for its deep, even black color and glassy surface. It carries the same dark aesthetic as black diamond at a fraction of the cost, with one important honest distinction: this stone is black onyx, not black diamond. They look similar in a kite cut at this size, but they're geologically different stones. We list it as onyx because that's what it is.

• Long associated with strength, protection, and grounding in crystal traditions
• Mohs 6.5–7 — softer than diamond but well within the durable range for stud earrings
• The opaque jet-black surface gives a more graphic, architectural look than the sparkle of a faceted dark diamond

Who They're For

• Anyone shopping black onyx earrings for everyday wear or as a gothic statement
• Dark academia, gothic, witchy, or Art Deco-leaning style preferences
• Bridesmaid gifts for black-tie or autumn weddings — onyx pairs beautifully with deep jewel tones, burgundy, and dark florals
• Birthday gifts (black onyx is associated with Leo and Capricorn zodiac traditions)
• Anyone who wears a kite-cut black engagement ring and wants coordinating earrings
