Our Wedding Bands


Suna Bros. has made platinum and 18 karat yellow gold wedding bands for over 70 years. To the casual observer, many wedding rings appear similar, however it is an attention to detail the distinguishes Suna Bros' rings from the rest.

Suna Bros. offers a wide selection of different styles providing rings to fulfill each wedding couples dream and budget. Starting with the most traditional channel set band in diamond, Suna offers rings with round brilliants, square cuts or carrés, princess cuts and baguettes as well as a combination of these cuts. In addition these classic styles are available in a combination of diamonds and colored gems such as ruby, sapphire, emerald, or even the more exotic green gem, tsavorite and finally Suna offers each style in varying widths to fit a range of finger sizes. Other styles using various setting methods, such as prong set or "fishtail" expand the vast selection of rings that has lead to the company's long established reputation for manufacturing excellence.

What makes the rings produced at Suna Bros special and differentiates each Suna ring from others available on the market? The experts at Suna Bros, Inc. believe attention to detail while following a long established process, without short cuts, produces a ring of heirloom quality. Here is a brief explanation of each step along the way.

Selecting a suitable "mounting"

Selecting the appropriate mounting starts a multiple step process. Most Suna mountings are die-struck, therefore seamless. Die-struck mountings have no "porosity" small pits and holes in the metal. Porosity is a frequent problem in mountings cast from a mold. Occasional rings must be made completely by hand, fabricated from solid metal plate. During this delicate and time consuming process individual supporting bars must be applied by hand in a precise position sometimes requiring the soldering of thirty or more bars for each ring.

Preparing each ring prior to setting

Preparation is essential to insure a quality product. The exact dimensions, both height and width of the stones to be used must be considered. These dimensions are based on the size and depth of the stones being used and are thus individual for each ring. Setting the stones correctly is impossible if the correct mounting is not selected and prepared before setting.

Envisioning a finished ring

Suna rings are designed with thicker walls allowing our highly skilled setters to finish each ring with a distinctive "knife edge" as opposed hammering the walls flat. This distinctive detail creates a more delicate and less metallic edge while allowing the walls to remain as substantial as possible.

Preparing Azures

One aspect of a beautifully crafted ring is the preparation of "Azures". Azures are the openings through which the stones can be viewed from the back. Following an old European tradition, Suna Bros. hand cuts azures into the ring which opens a pyramidal shape under each stone. Many manufacturers skip this process and drill a small hole though the ring for each stone. However, a hand-cut azure is a defining characteristic of a well made ring allowing light to enter each individual stone maximizing its brilliance. Without adequate light even the best stones may appear dull and lifeless.


Pre-polishing the inside channel of each ring is a particularly important step in wedding ring manufacturing. It is critical, particularly in rings that contain round stones, because the metal holding each stone cannot be polished to satisfaction after the stones are set. All Suna rings are pre-polished before setting.


All Suna wedding rings are set by hand rather than the more expedient machine method. Skilled artisans who specialize in channel setting bring their expertise to the process placing each stone edge to edge or "girdle to girdle" with little or no space between individual stones. Experience and skill is required to calculate the exact height at which to place the stones. Any error at this point — even by just a fraction of a millimeter, will result in an incorrect fitting of the stones or worse – the stones not fitting in the ring at all. The inside of the ring must now be lowered to the appropriate height, "seating" each stone securely in the channel rather than leaving it suspended. This is a common feature in rings manufactured and set by machine or inexperienced setters. Experienced setters make individual bearings along the inside wall securing each stone in place. After all the stones are set the top of each wall is finished with the trademark Suna "knife edge."

Polishing the final step!

Each ring is lapped on the outside wall to make it completely flat. The entire ring is polished to a mirror finish and is now ready for the close scrutiny of Suna's quality control team.
