Oval lab-grown ruby studs, each held in a carved scroll frame with a black onyx pear beneath and cubic zirconia at the crest and points. Solid 925 sterling silver with a rhodium finish, so the bright metal throws the red forward.

How the Pair Is Built
Crowned Crest
A round accent sits in a small carved crown above the center stone, echoing the crest on the Carmilla rings.
Scroll Frame
Two curls of carved metal sweep out from the oval, the same leaf-and-scroll vocabulary that runs through the family.
Onyx Drop
A black onyx pear sits below the center, held between carved leaves and closed by one more accent at the point.
These are the earring half of the Carmilla family and repeat the ring's design at a smaller scale. They wear as everyday studs rather than occasion pieces. Our guides to gothic earrings and earring types cover where a stud like this sits among the alternatives.
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. For earrings worn every day that hardness matters. Our guide to what ruby means covers the history, and garnet versus ruby is worth reading if you are choosing between the two reds.
These stones are 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 at matched sizes across a pair.
The pear beneath each center 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
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.
Frequently Asked Questions
Do these match the Carmilla ruby ring set?
Yes. They share 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.
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 matched sizes across a pair 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 each 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.
What kind of earring backs do they have?
Posts with butterfly push-backs. The post is solid sterling silver, and the backs are included.
Are they sold as a pair?
Yes — the price is for the pair, and both earrings ship together in one box.
What is it made of?
Solid 925 sterling silver throughout, hallmarked, with a rhodium finish for a bright white surface. No brass or base metal.
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 pair 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.
