How the Pendant Is Built
Tapered Bail
A plain polished bail carries the pendant and slides freely on the chain, so it always rights itself.
Scroll Frame
Two curls of carved metal sweep out from the oval, the same leaf-and-scroll vocabulary that runs through the Carmilla family.
Onyx Drop
A black onyx pear sits below the center, held between carved leaves and closed by one more accent at the point.
This is the necklace half of the Carmilla family and repeats the ring's design at a smaller scale. Our necklace length guide covers how an 18-inch chain sits, and how to layer necklaces is worth reading if you wear more than one. For the wider style, see our guide to gothic necklaces.
The Lab-Grown Ruby and Black Onyx
Ruby is corundum — the red variety — and corundum is a 9 on the Mohs scale, second only to diamond. Our guide to what ruby means covers the history, and garnet versus ruby is worth reading if you are choosing between the two reds.
This stone is lab-grown, with the same chemistry, hardness and optical behavior as mined corundum, in a saturated blood red that would be scarce and expensive in nature.
The pear beneath it is natural black onyx — opaque, evenly black, and the reason the red reads as vivid as it does. Our black onyx guide covers the material.
Metal and Accents
Pendant, bail and box chain are all solid 925 sterling silver with a rhodium finish — the same platinum-group metal used on white gold. The rhodium gives the bright white surface and shields the silver underneath from tarnishing.
The white accents are cubic zirconia. Moissanite or lab-grown diamond accents are available as a custom order.

Care
Ruby is 9 on the Mohs scale and among the most durable stones for daily wear; onyx is softer at 7 and prefers to avoid knocks. Clean with warm water, mild soap and a soft brush — our guide to cleaning sterling silver covers the method. Avoid abrasive polishes and chlorine, which wear the rhodium finish, and lay the chain flat in its velvet box rather than coiling it.
Frequently Asked Questions
Does this match the Carmilla ruby ring set?
Yes. It shares the carved leaf-and-scroll frame, the lab-grown ruby center and the black onyx of the Carmilla bridal set in sterling silver, so the pieces read as one family.
How long is the chain?
18 inches — princess length. It sits just below the collarbone on most necks, which is where this pendant is sized to hang.
Is the chain included?
Yes. The pendant comes on a solid 925 sterling silver box chain with a lobster clasp; nothing is sold separately.
Can the pendant be worn on another chain?
Yes. The bail is open enough to take most standard chains and cords, so you can move it onto a longer chain if you prefer.
Is the ruby real?
Yes. It is a genuine ruby — corundum — lab-grown rather than mined. Identical chemistry, hardness and color behavior. The difference is origin, not authenticity.
Why lab-grown rather than natural?
A saturated red at this size would be rare and very costly in mined corundum. Lab-grown gives the same material and the same 9 Mohs hardness at a fraction of the price, with a known origin.
Is the black onyx natural?
Yes. The pear beneath the center stone is natural black onyx.
Are the white accent stones diamonds?
No. They are cubic zirconia. Moissanite or lab-grown diamond accents are available as a custom order.
Is ruby a birthstone?
Yes — ruby is the July birthstone.
Will the silver tarnish?
The rhodium finish acts as a barrier, so it resists the darkening untreated sterling develops. The finish does wear thin after years of daily wear — we can refinish the piece when it does.
Are the stones ethically sourced?
Yes. All Aquamarise stones are conflict-free and responsibly sourced, and every order arrives in a free luxury velvet jewelry box.
