Rose gold necklace with 0.82 carat diamonds and onyx

The 18 carat rose gold floral necklace featuring natural black onyx and natural brilliant-cut diamonds is a fine jewellery creation curated by Pedro Luis Olivares Jeweller in Murcia. Conceived to deliver striking tonal contrast and refined presence against the décolletage, this piece reflects the goldsmithing heritage established in 1925 by José Olivares and Manolita Cano.

How is the architectural clover form of this black onyx necklace constructed?

The centrepiece presents a quatrefoil silhouette inspired by gothic and floral geometry, custom-carved from an opaque natural black onyx plaque finished with a mirror polish. The black gemstone is enclosed by a contoured 18 carat rose gold bezel with polished chamfered edges that define its outline.

At the centre of the onyx sits a four petal rose gold flower set with four main brilliant-cut natural diamonds in bezels, accented by a central accent diamond. The pendant suspends from a fixed bail connected to an 18 carat rose gold cable chain, dotted at calibrated intervals with natural diamonds set within bezel-mounted collets.

What benefits does contrasting black onyx with rose gold and diamonds provide?

The deep, pitch black surface of the onyx provides a monochromatic backdrop that intensifies the optical dispersion and fire of the white diamonds. Meanwhile, the warm tone of the 18 carat rose gold balances the stark contrast, imparting a contemporary, elegant aesthetic.

The addition of bezel-set diamonds along the chain provides visual continuity, ensuring points of light that move fluidly with the contours of the collarbone. The solid rear face of the motif ensures that the pendant sits flat and balanced during wear.

What are the qualities of our 18 carat rose gold alloy?

The pendant bezel, chain, and diamond collets are forged entirely in 18 carat gold, composed of 75% pure gold combined with copper and silver in precise proportions. This alloy retains its warm hue throughout the metal without requiring surface plating, maintaining its colour consistently over decades of wear.

From an honest technical viewpoint, black onyx is a cryptocrystalline quartz variety that benefits from mindful wear away from harsh chemicals or abrasives. At Pedro Luis Olivares Jeweller, our master jewellers in Murcia provide complete care services, including setting inspections, delicate cleaning, and professional repolishing.

Why is this pendant favoured for milestone occasions and evening wear?

The classic combination of black and rose gold imparts a timeless quality that transitions effortlessly from formal gala receptions to refined daytime occasions. Its proportions offer visual impact while maintaining a balanced profile against the neckline.

Its distinctive character makes it a memorable gift for anniversaries or personal achievements, wearing gracefully as a standalone statement or layered beside rose gold chains.
