The Lovers of the Dark™ collection is Aquamarise®'s dedicated black engagement ring line, built around black ruthenium finishes, dark stone combinations, and gothic-influenced design details that treat darkness as an aesthetic choice rather than a departure from convention. Every ring in this collection is finished in black ruthenium over 925 sterling silver, a finish that creates the deep, near-matte darkness that standard silver and gold cannot replicate. Stones throughout the collection include Herkimer diamond, black onyx, blue sandstone, and other dark, celestially influenced gemstones chosen specifically for how they perform against a black metal frame. Every piece is handcrafted using recycled metals and responsibly sourced stones, with verified hardness and honest care guidance on every listing.
What the Black Ruthenium Finish Is Made Of
Every ring on this page is built on a 925 sterling silver core, an alloy of 92.5% silver and 7.5% copper that runs solid through the whole piece. Black ruthenium is a platinum-group finish applied over that core, which is why the darkness reads as depth rather than as a surface color. Because the sterling underneath is a solid alloy rather than a coating, the silver content at the surface is the same as the silver content at the center, and it will not turn skin green.
Why Choose Lovers of the Dark™ Black Engagement Rings?
The Lovers of the Dark™ collection is created for those who have explored every conventional engagement ring and found nothing that truly reflects their taste. These rings are designed for buyers who are drawn to deeper tones, striking silhouettes, and a sense of distinction.
Black Ruthenium for the Aesthetic
The defining signature of the Lovers of the Dark™ collection is its black ruthenium finish over solid 925 sterling silver. Unlike ordinary black finishes, ruthenium creates a deeper darkness by absorbing light rather than reflecting it. This depth transforms every stone it surrounds. Herkimer diamond glimmers like distant starlight, while blue sandstone reveals its celestial shimmer. In this collection, the metal is not an accent or detail. It is the foundation, the dark, atmospheric canvas that allows every stone to shine with greater presence.
Celestial References With Dark Intention
The connection between the dark metal and the celestial reference is intentional: the darkness of space is the context that makes stars visible, and the darkness of the ruthenium finish makes the sandstone inlay read as luminous rather than merely decorative. For instance, the Evelyn Starry Night Ring Set in Black Ruthenium draws its design from the Great Rift Nebula, using glittering sandstone to replicate the texture of stars across a dark sky within a black ruthenium band. It is one example of several celestially referenced designs in the collection in which the aesthetic darkness and the meaning behind the ring work together.
Gothic Detail With Fine Jewelry Craft
Gothic-adjacent design does not mean crude or rough at Aquamarise®. For example, this collection features the Shadow Queen Black Onyx Lotus Ring in Black Ruthenium, which has a marquise-cut natural black onyx center stone framed by intricate lotus-inspired detailing with additional black onyx accents, a design that is bold and dramatic without sacrificing the craft standards applied across every piece in the collection. It is one example of several detailed, motif-driven designs in this collection for buyers who want the ring to carry more than an aesthetic.
For the Non-Traditional Buyer Who Knows Exactly What They Want
The Lovers of the Dark™ collection exists specifically for the buyer looking for dark metals, meaningful stones, design details with specific references, and a standard of craft that treats the gothic and celestial aesthetic as worthy of the same fine-jewelry construction applied to any other ring at Aquamarise®.

Caring for a Black Ruthenium Ring
Rinse with lukewarm water and a drop of mild soap, work gently with a soft brush, then dry the ring completely before storing it away from harder stones. Skip ultrasonic cleaners and abrasive polishes: several stones in this collection sit at the softer end of the scale, including black onyx and green moss agate at 6.5 to 7 on the Mohs scale, and both are happiest in protective settings. Harder centers such as ruby, a red corundum at Mohs 9, and red garnet at 6.5 to 7.5 handle daily contact more easily, though the same gentle routine keeps the black ruthenium finish at full depth. Every listing names its stone and metal, and the full routine is on our jewelry care and warranty page.
