A vintage-inspired teardrop black onyx engagement ring set in solid 925 sterling silver. The center stone is a natural black onyx cut in a 5.0 x 7.0 mm teardrop — roughly 1.4 carats of deep, unbroken black — and it is paired with a second oval-cut onyx ring on a matching 1.7 mm band, designed to be worn stacked or apart.

What you receive
Ring One — The Onyx Ring
Teardrop-cut natural black onyx, 5.0 x 7.0 mm, approximately 1.4 ct, framed by small accent stones on a vintage-inspired gallery.
1.7 mm sterling silver band.
Ring Two — The Oval Onyx Ring
A second black onyx stone in an oval cut, set on a matching 1.7 mm sterling silver band.
Designed to sit flush beside the teardrop and to wear equally well on its own.
Both rings are sold together as one set. Pairing a teardrop with an oval is a deliberate choice — two rounded shapes in different proportions read as one considered stack rather than a duplicate, and because the band profiles match at 1.7 mm they sit flush against each other without gapping.
Black onyx, not black diamond
This is worth stating plainly, because the two get conflated constantly in the alternative bridal market: the center stone here is natural black onyx, a chalcedony quartz, not a black diamond. Onyx gives you something a black diamond cannot — a completely opaque, glass-smooth, evenly saturated black with no internal glitter or salt-and-pepper mottling. It reads as pure shadow. A black diamond, by contrast, is a heavily included stone that scatters light unevenly and costs many times more.
If you want the full picture on how onyx compares to black spinel, black diamond, and the other dark stones used in engagement rings, our complete guide to black gemstones breaks down hardness, price, and appearance side by side. For the symbolism and folklore behind the stone specifically, see black onyx meaning.
Why the teardrop cut works on a black stone
The teardrop — also called the pear cut — has one rounded end and one point. On a transparent gem, that shape is chosen for brilliance. On an opaque stone like onyx, it does something different: the point creates a clear directional axis that elongates the finger, and the polished dome of the rounded end catches a single soft highlight instead of fracturing light into a hundred small ones. The result is a stone that looks carved rather than sparkled.
Set with the point toward the fingertip, as it is here, the teardrop is one of the most flattering shapes available on a slim band. If you want to see the shape across other stones and metals, browse our pear shaped engagement rings.
The vintage-inspired setting
The gallery under the stone is worked in the older tradition — detail carried around the sides of the setting rather than concentrated on the face, so the ring is as finished from the side profile as it is from above. That construction is what separates a genuinely vintage-styled ring from a modern solitaire with a dark stone dropped into it.
Victorian and Edwardian jewelers used jet and onyx heavily, which is part of why a black stone reads as antique to the eye even in a newly made ring. Our guide to Victorian gothic engagement rings traces where that visual language came from. For more pieces in the same register, see our antique and vintage engagement rings.
What black onyx means
Onyx has been a protective stone for as long as it has been worn. In Roman practice it was carried as a grounding talisman; in Victorian mourning jewelry it stood for constancy and memory. In a modern engagement ring it tends to be chosen by people who want the commitment marked in something unambiguous and permanent rather than something sparkling — a promise stated quietly.
It is also, straightforwardly, one of the most versatile stones in fine jewelry. Black goes with everything. If you are drawn to that register generally, our women's black rings and the wider black onyx engagement rings collection cover the full range from minimal to ornate.

Sizing and care
Both rings run true to size and are finished with a comfort-fit interior, so the band curves slightly inward at the edges and slides over the knuckle more easily than a flat band of the same width.
Onyx sits at 7 on the Mohs scale — hard enough for daily wear, but not diamond-hard. Take the set off before cleaning with household chemicals, swimming in chlorinated water, or anything involving impact. Clean with warm water, a drop of mild soap, and a soft cloth; skip ultrasonic cleaners and steam, which can be harsh on porous and dyed stones.
Solid 925 sterling silver will not turn your skin green — that reaction comes from copper-heavy alloys and plated base metals, neither of which is used here. Silver can develop a surface tarnish over time, which is normal and removable. Our guides on whether sterling silver turns green and how to clean sterling silver cover both in full.
Frequently asked questions
Is this ring set black onyx or black diamond?
Black onyx. The center stone is a natural black onyx, which is a chalcedony quartz — not a diamond. Onyx is fully opaque with an even, unbroken black color, while black diamonds are heavily included stones with visible internal texture.
Is the black onyx natural?
Yes. The center stone is natural black onyx, not a simulant or a lab-created stone.
How many rings come in the set?
Two. The teardrop onyx ring and a matching oval onyx ring, sold together as one set at a single price.
What size is the center stone?
The teardrop onyx measures 5.0 x 7.0 mm, which works out to approximately 1.4 carats.
What metal is the Amy ring set made from?
Solid 925 sterling silver throughout — both rings, and the setting. There is no plating and no base metal core.
Will sterling silver turn my finger green?
No. Solid 925 sterling silver does not cause skin discoloration. That reaction is associated with copper-heavy alloys and plated base metals, which are not used in this set.
What is a teardrop cut?
A teardrop cut, also called a pear cut, has one rounded end and one tapered point. On the hand it creates a lengthening line along the finger, which is why it is one of the most flattering shapes on a slim band.
Is black onyx durable enough for an engagement ring?
Yes, with normal care. Onyx is a 7 on the Mohs scale, the same hardness as quartz and amethyst. It handles daily wear well but should be protected from impact and harsh chemicals.
Are both stones the same shape?
No. The first ring holds a teardrop-cut black onyx and the second holds an oval-cut black onyx. The two shapes are paired deliberately so the stack reads as one designed set rather than a repeated ring.
Can I wear either ring on its own?
Yes. Both rings are designed to stand alone as well as stack. Many people wear the teardrop ring by itself day to day and add the oval for occasions.
How wide are the bands?
Each ring has an average band width of 1.7 mm, which is a deliberately slim profile. Because both rings share the same width, they sit flush when stacked.
What does black onyx symbolize?
Onyx is traditionally associated with protection, grounding, and constancy. In Victorian jewelry it carried strong associations with memory and enduring devotion, which is part of why it reads so naturally in a commitment ring.
Does the set come with a ring box?
Yes, a free ring box is included with every order.
How quickly does it ship?
This set is ready to ship the next business day, with free shipping within the USA.
Would this work as a promise ring or an anniversary gift?
It works well for both. Because it is a two-ring set, some people give one ring as a promise ring and add the second at a later milestone.
How should I clean a black onyx ring?
Warm water, a drop of mild dish soap, and a soft cloth or soft toothbrush. Rinse and dry fully. Avoid ultrasonic cleaners, steam cleaners, and any solution containing bleach or ammonia.
