Ring Sizing

Find your ring size.

Not sure? Use a ring you already own, or measure with a string. If the size is off, you are covered: 30-day exchange on unengraved rings, and Lifetime Sizing for the original purchaser after that.

Three Ways to Find Your Size

Pick the path that fits.

01
Use a Ring You Own

How to Measure

Two methods, both accurate.

Method A: Use a ring you already own

01
Find a ring that already fits the correct finger comfortably.
02
Place the ring on paper and trace the inside circle.
03
Measure the inside diameter across the widest point. Match it to the chart below.

Method B: String and a ruler

01
Wrap a string snug at the base of the finger.
02
Mark the spot where the string overlaps.
03
Measure the marked length. Match the circumference to the chart.

A few notes from the workshop

  • Measure at the end of the day. Fingers are larger by then.
  • Measure the hand the ring will live on. The dominant hand is usually a half-size larger.
  • A wider band (6mm+) wears a half-size tighter. If between two sizes, size up.

About Black Ceramic

Black ceramic is a high-tech engineered material. It's harder than steel, lighter than tungsten, and the color is permanent. Unlike black-coated metal rings (PVD or IP plating) that wear off at the edges over time, the BARRACUDA's black goes all the way through. It won't fade, chip color, or develop bare patches.

Ceramic is highly scratch-resistant but brittle under sharp impact. Drop it on a hard surface and it can chip. The flip side: in an emergency, ceramic rings can be cracked off the finger quickly with standard ER tools.

Black ceramic is hypoallergenic (no nickel), holds its mirror finish without polishing, and is noticeably lighter on the finger than tungsten. The BARRACUDA stays glossy with a soft cloth, no jeweler's polish required.

What makes our BARRACUDA different

Custom engraved in our Irving, Texas shop. Aydins Jewelry has been selling rings since 2011, with over 10,000 orders shipped.

  • Free US shipping on every BARRACUDA order
  • Free inside laser engraving (date, initials, coordinates, phrase, whatever you want)
  • Lifetime warranty against manufacturing defects
  • Lifetime sizing: if it doesn't fit, send it back any time and we'll swap the size
  • 30-day returns from receipt on unworn rings

Sizing & Fit

The BARRACUDA is comfort fit, meaning the inside of the band is rounded rather than flat, which makes it easier to slide over the knuckle and more comfortable for all-day wear. Comfort-fit rings typically size a half-size smaller than standard-fit rings, so if you normally wear a size 10 standard-fit, you'll likely wear a 9.5 in the BARRACUDA.

Available sizes: 4 – 14, including half sizes.

Not sure what size you wear? Use our free ring sizing guide, or order any size and use our lifetime sizing to swap if it doesn't fit perfectly the first time.

Care Instructions

The BARRACUDA's black ceramic is color-stable for life, with no plating to wear off and no need for refinishing. Wipe with a soft cloth for daily clean, warm soapy water for deeper buildup. Avoid drops on tile or concrete (ceramic is hard but brittle) and skip abrasive cleaners.

Engraving

Every BARRACUDA includes free inside laser engraving. Add a wedding date, initials, coordinates, or any phrase up to 30 characters. Engraving is permanent, professionally applied, and does not delay shipping.

Frequently Asked Questions

What color is the BARRACUDA?
The BARRACUDA features blue & purple.

What sizes does the BARRACUDA come in?
The BARRACUDA is available in sizes 4 – 14, including half sizes. If you're between sizes, lifetime sizing is included, so you can order, try it, and swap if needed.

What width is the BARRACUDA?
The BARRACUDA is offered in 6 & 8 & 10mm widths. Both widths are available so couples can match their bands.

Is the BARRACUDA comfort fit?
Yes. The BARRACUDA is comfort fit, meaning the inside of the band is gently rounded so it slides over the knuckle easily and sits flat against the finger. Most wearers find it comfortable enough to forget they're wearing it.

Is the BARRACUDA durable for daily wear?
Black ceramic is highly scratch-resistant and the color goes all the way through, so it doesn't wear off the way coated black rings do. The BARRACUDA stays glossy for life with minimal care, though ceramic can chip if dropped on hard surfaces.

Is the BARRACUDA hypoallergenic?
Yes. The BARRACUDA is nickel-free and hypoallergenic, safe for sensitive skin and people with metal allergies.

Can the BARRACUDA be engraved?
Yes. Free inside laser engraving is included with every BARRACUDA. You can add a date, initials, a phrase, or coordinates. Engraving doesn't delay shipping.

What if the ring doesn't fit?
Lifetime sizing is included with every BARRACUDA. If it doesn't fit, ship it back and we'll send a different size, even years after the original purchase.

How long does shipping take?
Free standard shipping ships within 1-2 business days from our Irving, Texas shop and arrives in 3-5 business days within the US. Most BARRACUDA orders arrive within a week of ordering.

What is Aydins' return policy?
See our returns and exchanges page for full details.

Can the BARRACUDA be cut off in an emergency?
Yes. Both tungsten and ceramic rings can be safely removed in an emergency. Hospitals use a tool that cracks the band cleanly off the finger without needing to cut through it. This is actually a safety advantage over gold or platinum, which require more time-consuming cutting.

Lifetime Warranty

Every Aydins ring is covered by a lifetime warranty against manufacturing defects. If something fails because of how the ring was made, not how it was worn, we'll take care of it through our warranty process.

What's Covered

  • Manufacturing defects in the ring or its finish
  • Premature failure of plating, coatings, or inlays under normal wear
  • Stone setting failure caused by the manufacturing process
  • Defects in the metal or material itself

What's Not Covered

The warranty covers how we built the ring, not what happens to it after you take it home. The following aren't covered:

  • Damage from drops, sharp impact, or excessive force
  • Wear caused by chlorine, harsh chemicals, abrasive cleaning, or improper care
  • Lost rings
  • Damage from at-home sizing or resizing attempts (always use the Lifetime Sizing Program)
  • Normal cosmetic wear over time on softer metals (small scratches, patina)

Aydins Lifetime Sizing Program

Your finger size will change over the years. The Lifetime Sizing Program is how we make sure your ring keeps fitting, no matter how long you've owned it.

It works like this:

  • If your size changes at any point in your life, we will send you the same ring in your new size for a small re-sizing fee, not the full retail price.
  • You ship your original ring back to us, and we ship the replacement out to you.
  • The full process is handled through our Returns & Exchanges portal, so you can track everything from start to finish.

The exact process depends on the metal (some can be resized, others are replaced), but the outcome is the same: you stay in a ring that fits, for life.

How to File a Claim or Request a Resize

Visit our Returns & Exchanges page to start any warranty claim, resize request, or return. You'll be guided through our self-service portal, where you can submit your claim, upload photos if needed, and track status from start to finish.

For warranty claims, please include a clear photo of the ring so we can confirm coverage before shipping a replacement.

Our Promise

Aydins has been making rings since 2011. The warranty and the sizing program exist for one reason: a wedding band is supposed to last as long as the marriage. We build the ring to do that, and we back it for as long as you wear it.

FAQ's

How does inside engraving work?

Free with every order. You can engrave text, dates, coordinates, fingerprints, handwriting, signatures, or a custom image. Standard fonts are included; if you want a specific font or custom artwork, send us a sample after checkout and we'll match it. Engraving is permanent and laser-etched, not stamped.

Do you offer custom sizes or widths?

Yes, within reason. We can do half sizes, sizes below 5 and above 15, and non-standard widths on most styles. Reach out before ordering with what you need and we'll quote the timeline. Some materials (ceramic, full-engraved patterns) have manufacturing limits we'll be upfront about.

Which material is right for me?

Tungsten is hardest and most scratch-resistant; great for daily wear and active hands. Titanium is lighter, hypoallergenic, and softer in feel. Ceramic is hard like tungsten but lighter and a true permanent black. Solid 14k gold is softer than tungsten and will pick up character marks over time, which most buyers like; pick gold if you want a traditional precious metal. Each ring's Material tab covers the specifics for that piece.

Are your rings really handcrafted?

Yes. Every Aydins ring is hand-finished, hand-inspected, and hand-engraved in our workshop before it ships. We've been doing this since 2011. That's why standard turnaround is 1 to 3 business days and not same-day; the quality check takes a beat.

Free Shipping

Every order ships free anywhere in the United States with no minimum. Free shipping is also available to Canada, Australia, and the United Kingdom on orders of $90 USD or more.

Processing Time

Most orders ship within 1 to 5 business days. Engraved rings, custom sizes, and special widths can add a day or two; we'll let you know if your order needs extra time.

Express and Next-Day Delivery

Available at checkout for an additional fee. Express options reduce transit time after the order ships, but standard processing time still applies before the package goes out.

In-Store Pickup

Available within 1 to 5 business days for local customers. Select pickup at checkout.

International Shipping

We ship worldwide to most countries. If yours isn't listed at checkout, contact us and we'll work something out. Delivery times vary by destination. UPS and FedEx Express options are available for faster international transit.

Returns and Exchanges

For the full process, visit our Returns & Exchanges page. Size exchanges, defects, and warranty claims are all handled there.

What Ceramic Is

Ceramic, in jewelry terms, refers to high-tech advanced ceramic, not pottery. It's typically made from titanium carbide or zirconium oxide compounds that are kiln-fired at extreme temperatures into a dense, hardened material. The result is a wedding band that's lighter than tungsten, harder than titanium, and finished in a color that's part of the material itself rather than a coating.

The same family of ceramics is used in luxury watch cases (Rado, Hublot, Omega) and high-performance industrial applications. For wedding bands, it's the modern alternative to traditional metals.

Why People Choose It

     
  • Permanent color, all the way through. Black ceramic is black throughout the material. White ceramic is white throughout. The color can't chip, fade, or wear off because it isn't on the surface, it's the material.
  •  
  • Highly scratch-resistant. Ceramic rates between 7 and 8 on the Mohs scale, harder than titanium and most precious metals. It holds its finish under daily wear.
  •  
  • Lightweight. Ceramic is about 40% lighter than tungsten and lighter than most gold rings. Comfortable for all-day wear without the heaviness some men dislike.
  •  
  • Hypoallergenic. Ceramic is biologically inert, so there's no reaction with the skin and no metal allergies to worry about.
  •  
  • Smooth, modern feel. The polished surface has a distinctive silky finish that's different from any metal. People often comment on the way ceramic feels the first time they put one on.

The Tradeoff Worth Knowing

Ceramic's hardness is also its limitation. Like tungsten, ceramic can crack or shatter under sharp impact. This is rare in normal wear, but it's worth understanding before you buy.

Two practical things follow from this:

     
  • It can't be cut off the finger with traditional ring saws. In an emergency, a hospital uses a small tool to crack the ring at two points, which removes it cleanly. Most ERs are familiar with this.
  •  
  • Resizing isn't possible. If your size changes, we replace the ring through the Aydins Lifetime Sizing Program rather than try to alter it. It's how high-tech ceramic works.

Comfort Fit, Explained

Every Aydins ceramic ring is built with a comfort-fit interior. The inside of the band is gently domed instead of flat, which reduces friction against the finger and makes the ring sit smoothly even when your hand swells slightly (heat, humidity, exercise, long flights).

One note on sizing. Comfort-fit rings often run a half size larger than standard fit, so if you've measured for a non-comfort-fit ring before, order a half size down. If you're unsure, our Ring Sizing Guide has three different ways to find your size at home.

Color Options

Ceramic comes primarily in two colors, both intrinsic to the material:

     
  • Black ceramic. A deep, neutral black that doesn't fade or wear. The most popular choice in the category and a clean alternative to black-plated tungsten, since ceramic doesn't have a plated layer that can wear over time.
  •  
  • White ceramic. A bright, modern white that resembles white gold or platinum but never tarnishes, yellows, or needs replating. A favorite among buyers who want the look of white gold without the upkeep.

Care & Cleaning

     
  • Clean with mild soap and warm water, dry with a soft cloth.
  •  
  • Skip the ultrasonic cleaners and chemical jewelry dips. Ceramic doesn't need them.
  •  
  • No special precautions for showering, swimming, or chemicals. Ceramic is inert and doesn't react.
  •  
  • The surface holds its polish under normal wear, but avoid dropping the ring on hard surfaces. Like all hard ceramics, the same property that resists scratches makes the material vulnerable to sharp impact.

Lifetime Coverage

Every Aydins ceramic ring is backed by a lifetime warranty against manufacturing defects and the Aydins Lifetime Sizing Program. If your size ever changes, we get you into a ring that fits through the sizing program. Both are handled through our Returns & Exchanges portal, and the full warranty terms are listed on the Warranty tab.

The promise behind both is simple: a wedding band is supposed to last as long as the marriage. We build the ring to do that, and we back it for as long as you wear it.
