Disclosure:This guide compares one brand’s collection. Prices, ratings, and product details were read from ronatelli.com on October 29, 2026; our buying advice applies to any brand.
Ronatelli sells eleven men’s rings, all in 925 sterling silver and all in one adjustable size, from $129 to $169. They fall into three families: four statement rings set with black onyx, three signet rings, and four all-silver bands. The product pages give you a price, a rating, and a short description, but no band width or weight, and they don’t put the rings side by side. This guide does: all eleven in one table, how the one-size fit works, what sets each ring apart, which to pick for your hand and wardrobe, and what the reviews say. Prices move and ratings shift as reviews come in, so treat the numbers as a snapshot and check the product page before you order.
Key takeaways
- Eleven rings, $129 to $169: four black onyx statement rings (Ragnar, Troy, Arco, Nero), three signets (Horus, Agno, Marmo), and four all-silver bands (Torin, Nexus, Etna, Kleos).
- One size for every ring. Each one adjusts by hand at the back of the band, so there is no ring size to choose. Like any adjustable ring, it covers a range of sizes, not every size.
- The Ragnar is the clear best seller: 93 of the collection’s 136 reviews, at 4.7. Among rings with more than a handful of reviews, the Troy has the highest average, 4.9 from 17.
- No widths or weights are published, except the Torin’s 6.5 g, so the worn photos are the best guide to size.
- Safest first picks: the Torin ($129) for plain silver, the Ragnar ($149) for a stone.

All eleven at a glance
Every ring is listed as 925 sterling silver and sold in one adjustable size. Grouped by what sits on top, the eleven fall into three families: a black onyx, a flat signet face, or no stone at all.

One size: how the adjustable fit works
None of the eleven comes in ring sizes. Ronatelli sells each one as “one size fits all,” and its size guide says every ring is adjustable: slide it on, squeeze it gently to make it smaller or ease it open to make it larger, and stop when it sits comfortably without spinning. The product photos show how the back of the band is made. On most of the rings it is split, with the two ends overlapping; the Etna and the Kleos are open bands with a small gap between the ends. The photos also show an S925 stamp inside the band.
Ronatelli’s guide says the rings fit any finger. Read that as a range rather than every size: an adjustable ring moves across the sizes in the middle, not from a pinky to a thumb. Men’s rings are mostly sized 8 to 13, so if you wear well outside that, ask Ronatelli before you order; one Ragnar buyer found it a little delicate to adjust for a large finger while keeping it round, as the reviews section below explains.
Adjust it once, slowly, and leave it there. Press on the band, not on the stone or its setting, and don’t bend it back and forth, which hardens the silver and can eventually crack it; Ronatelli’s own care notes say the same. Its lifetime warranty covers manufacturing faults such as a weak solder joint, but not damage from bending or force. Our guide to adjustable rings walks through the fitting step by step, and our guides to finding your ring size and finding his size without asking cover the sizes themselves.
Black onyx statement rings: Ragnar, Troy, Arco, Nero
Four rings carry a black onyx on top, set in silver with detail down the sides. They are the boldest pieces in the collection and, in the worn photos, about as wide as the finger at the top. Onyx is one of the stones our ring buying guide lists as holding up well to daily wear; what differs is how the stone is held.
Ragnar, $149. A faceted black onyx in a square silver frame, with chain-textured bands down both sides. The frame wraps the edges of the stone, which protects them better than prongs do, and the look is plain enough for every day. With 93 reviews at 4.7, it is the ring most Ronatelli buyers choose.
Troy, $149. A smooth black onyx held by arrow-tip prongs at its corners, with rows of small dark stones along the shoulders. It has more detail than the Ragnar and looks more formal up close. Its 4.9 from 17 reviews is the highest average among rings with more than a handful.
Arco, $169. A large faceted onyx, in Ronatelli’s words, held by claw prongs and ringed with small onyx accents, with floral engraving on both sides. It is the most expensive ring and the biggest statement, with four reviews so far, at 3.8.
Nero, $149. A faceted onyx raised high in an ornate setting, ringed with small onyx accents, with antique-style scrollwork around the band. The most old-world look of the four; 4.8 from four reviews.
Prongs and raised settings catch on knitwear and pockets more than a frame does, so check the Troy’s, Arco’s, and Nero’s prongs now and then, along with the small accent stones, when you clean the ring. Our guide to black onyx rings covers each setting and how to clean around it.
Signet rings: Horus, Agno, Marmo
A signet has a flat face on top. Our signet ring guide is about plain and engraved faces; Ronatelli’s three are decorated instead, with stones or a motif, so there is nothing to engrave. All three cost $139 or less.
Horus, $139. A winged figure rising from a bed of small black onyx stones, inside a braided silver border, with scrollwork down the sides. Ronatelli names the figure as the Faravahar, the winged symbol from ancient Persia that is associated with Zoroastrianism and widely used today as a symbol of Iran. Like a cross or the vajra, it carries meaning for many people, which is worth knowing before you wear or give it. 4.8 from five reviews.
Agno, $129. A six-sided face packed with small pavé-set onyx stones, with geometric engraving on every side. The hexagon is an unusual shape for a signet, and the face sparkles from the stones rather than shining like polished silver. 4.7 from three reviews.
Marmo, $129. A square matte black stone veined in white, in a smooth frame with engraved sides; Ronatelli doesn’t name the stone. The cleanest and most modern of the three, with 4.0 from two reviews.
The pinky is the traditional finger for a signet, as our signet guide explains, but a pinky usually runs three to four sizes smaller than the ring finger, so check that the ring closes far enough before you settle there. The ring finger of the right hand is the usual alternative.
All-silver bands: Torin, Nexus, Etna, Kleos
Four rings have no stone at all. They are the easiest to wear every day, sit well beside a watch or a wedding band, and, being textured, hide scratches better than a polished band; the finishes section of our ring buying guide explains why.
Torin, $129. Curb-chain links shaped into one polished band, so it looks like a length of chain wrapped around the finger. It is the only ring with a published weight, 6.5 g in its product listing. The back is a flat band that slides under the links to adjust, and one reviewer who was unsure about a one-size ring says he likes it now. 4.7 from seven reviews.
Nexus, $129. A braided band of interlocking silver sections that cross over one another. Ronatelli added it in September 2026, and it has no reviews yet. If he already wears a braided bracelet, such as the Lesi, it is the natural match.
Etna, $129. A wide band with a rough, rock-like surface of ridges and cracks, darkened in the recesses, as the photos show; the inside is smooth. One review so far, at 5.0.
Kleos, $149. A Greek key border along both edges and a repeating angular pattern down the middle, also darkened in the recesses. It was added in September 2026 too and has no reviews yet. The Greek key is the meander pattern our guide to symbols on bracelets explains, and it matches Ronatelli’s Athena bracelet.
The Etna and the Kleos are darkened on purpose. Clean them with a soft cloth on the raised surfaces and mild soap and water, never a dip or a foil bath, which would lift the dark finish; our guide to oxidized silver explains how that finish ages.
Which one: by hand, wardrobe, and budget
- A first ring. The Torin ($129): plain silver, a classic chain pattern, and nothing to catch. The Nexus ($129) if he prefers texture.
- A stone ring for every day. The Ragnar ($149): the frame protects the stone, and it has the longest review record in the collection.
- The most detail. The Troy ($149), or the Nero ($149) for an antique look.
- The biggest statement. The Arco ($169), with the largest stone. It has few reviews so far.
- A signet. The Marmo ($129) for a clean, modern face, the Agno ($129) for stones, or the Horus ($139) for a symbol that means something to him.
- Beside a wedding band. An all-silver band on the other hand: the Torin, the Etna, or the Kleos.
- To match a bracelet. The Kleos with the Athena Greek key bracelet, the Torin with a curb bracelet such as the Bari, or the Nexus with the braided Lesi. Our comparison of Ronatelli’s bracelets lists them all.
- As a gift. Any of them: one size means no guessing. If he already wears a ring, stay in the same family; our holiday gift guide covers the rest.
- Under $130. The Torin, Nexus, Etna, Agno, and Marmo, all at $129.
Reviews, delivery, and the fine print
The ratings in the table are the averages the product pages show, with the number of reviews behind them. The Ragnar has 93 of the collection’s 136 reviews, and 88 of those give four or five stars. Most of the other rings have fewer than ten, and the Nexus and Kleos, added in September 2026, have none yet, so their averages say little so far.
We read the rings’ reviews for what buyers say about the one-size fit. Fourteen mention it approvingly, from “fairly easy to adjust” to being able to move the ring to another finger. Four Ragnar buyers had trouble at first: two found it too small until they worked out how to adjust it (one, who thought he had ordered a size 13, came back to say it is perfect), one found it a little delicate to adjust for a large finger while keeping it round, and two said they couldn’t find instructions for adjusting it. If you wear a large size, ask Ronatelli before you order.
The most common complaint, in eleven reviews, is a slow delivery, as it is across Ronatelli’s other pieces; our roundup of Ronatelli customer reviews covers it. Shipping is free and tracked. Ronatelli quotes one to two business days to process an order, then two to three business days from a warehouse in your country or four to seven from overseas.
Returns are accepted within 30 days of receiving the ring, unworn and with its tags and original packaging; you request the return first, and the return postage is yours. A different ring means a return and a new order. The lifetime warranty covers manufacturing faults, not wear, harsh chemicals, or bending. Our Ronatelli brand profile covers the brand itself, and you can browse Ronatelli’s ring collection for the current prices.
FAQ
Are Ronatelli rings adjustable?
Yes. Every ring in the collection is sold in one adjustable size. The back of the band is split or open, so you squeeze it gently to make it smaller or ease it open to make it larger.
What ring size do Ronatelli rings fit?
Ronatelli says they fit any finger and gives no size range. Like any adjustable ring, they cover a range rather than every size; if you wear well outside the usual men’s 8 to 13, ask before you order.
Which Ronatelli ring is the most popular?
The Ragnar, a square black onyx ring at $149, with 93 reviews at 4.7 when we checked. Among rings with more than a few reviews, the Troy has the highest average, 4.9 from 17.
Are Ronatelli rings real silver?
The product pages describe every ring as 925 sterling silver, and the product photos show an S925 stamp inside the band. Our guide to telling if silver is real explains the stamp and the tests you can run at home.
What is the cheapest Ronatelli ring?
Five rings cost $129: the Torin, Nexus, Etna, Agno, and Marmo. The Arco is the most expensive, at $169.
Can a Ronatelli ring be resized?
There is nothing to resize: you adjust it by hand. Do it slowly and as few times as you can, and press on the band rather than the stone. Damage from bending isn’t covered by the warranty.
Bottom line
Decide what sits on top first. For one ring that goes with everything, the Torin at $129 is the plain-silver choice and the Ragnar at $149 the stone ring with the longest track record. Go to the Troy, Nero, or Arco for more detail and a bigger stone, to the Marmo, Agno, or Horus for a signet, and to the Etna, Kleos, or Nexus for texture without a stone. Every ring is one size, so there is no ring size to guess; adjust it gently, and check the product page for the price on the day.
