Things You Should Know: About Tension Settings and Selecting the Right Diamond

Tension Set Concept:

Tension Concept: There are four tension set companies in the world that manufactures tension set products, Gelin Abaci is one of the two companies in the United States. Gelin Abaci is considered the largest manufacturer of tension set diamond rings in the world. Tension set concept is more than 40 years old. Latest Awards - Highest Awards - Named "Best Ring Design" by JCK Jeweler's Choice Awards 2013. View Details.

Tension Settings:

A tension setting is a unique process used for a ring, pendant, or earring that holds a gemstone in place by applying pressure.

What Is A Tension Setting?

The spring loaded metal in a tension setting has small etchings/ grooves to the metal creating a seat or cradle like action for the gemstones edges to lock into place. This creates the appearance that the gemstone is floating.
Tension Mounting: A tension setting allows the maximum amount of light to pass through the center stone creating extraordinary brilliance superior to all traditional settings.

How Do Tension Settings Work?

In-order to make a tension setting GelinAbaci must work to harden the metal, employ special alloys, and pressure treat the metal to create the superior strength that is required for the spring loading process to occur. GelinAbaci tension settings are manufactured in 14k, 18k, and 950 platinum. GelinAbaci has the largest selection in tension settings in the world. Each tension setting exerts from 65 to 95lbs of pressure per millimeter which equates to 12,000 pounds per square inch on a diamond or any other gem stone. Any gemstone with a hardness of 9 or above on the Mohs hardness scale can be tension set.

What Makes Tension Settings Unique?

There are several differences in tension settings compared to traditional settings (prong settings, bezel settings, etc). One of the main differences is that a tension setting is custom tailored to each individual's style of choice, center diamond size, center diamond shape and finger size whereas most other settings are already constructed and manufactured.GelinAbaci uses a scanning device to identify the exact places where pressure has to be applied on the stone.Tension settings are crafted and calibrated to the exact detailed measurements of the gemstone that it will be holding.GelinAbaci tension settings can be sized a ? size larger in most cases. This process reassures that customer's can keep their customized piece perfectly fit even if they may experience weight fluctuation after their purchase. Sizing program options are available if a larger or smaller size adjustment is required (contact an authorized GelinAbaci jeweler for details).A tension setting shows off the beauty of the center diamond at its best!

Tension Setting vs. Prong Setting?

There may be some conflicting perspectives on security when looking at buying a tension setting. It's OK! It's normal. GelinAbaci tension rings are at least as safe or safer for your diamond then traditional four and six prong settings.To answer the question, "Is my diamond secure in my tension ring"? The answer is YES!It is highly unlikely for someone to lose a stone in a tension ring, as they are constructed using a spring loading effect from the customized metal choice in which weakening cannot occur.Prong settings can snag on clothes and other objects leading to the loosing and weakening of the prongs over time and use. This allows heavy maintenance of prong settings often and replacement periodically. Tensions settings allow for less maintenance. Prong settings only apply 6-8 pounds of pressure (per prong) to the stone to keep it secure where tensions settings apply more than three times that amount.It can be said that yes, both prong and tension settings have to be exposed to a tremendous amount of high impact and or accidental damage from day to day wear and tear to affect the stone. Prong settings can be exposed to high impact and suffer a greater effect of losing a stone because the prongs need to be replaced. Tension settings do not have to be replaced like prongs, unless there are damages to the tensile strength (memory of the metal) which makes it highly unlikely for customers to lose their diamonds or gemstones.

Tension Set Manufacturing

Tension set ring settings in platinum & gold (yellow & white gold) are manufactured with special alloys by a sophisticated technique which enables the metal to retain it's memory. Depending on the style, tension set products have anywhere from 65 to 95 pounds pressure on the center diamond. TR-300 is a piece of art at its finest moment.
