Settings | Tension Set Rings:
Diamond, ruby and sapphire in tension set rings are popular
as engagement setting and also as anniversary ring. The tension set
ring concept is more than 40 years old. More than 50,000 tension
setting/tension set diamond rings have been sold. Our tension set
diamond rings are manufactured by Gelin and Abaci (G.A.I.) and not by
Steven Kretchmer. There have been no known diamond losses due to
design or craftsmanship of tension set ring. Every tension set ring
is closely inspected to ensure it meets the high standards. Each
tension ring is custom made for a specific diamond size and finger
size. Each tension product is manufactured with special alloys with a
sophisticated technique which enables the metal to retain its memory.
Tension set products have anywhere from 65 to 95 pounds pressure on
the center stone.

Tension
Settings Mfg:
Tension set products (rings & settings) are manufactured with
special alloys by a sophisticated technique which enables the metal
to retain it's memory. Depending on the style, tension products have
anywhere from 65 to 95 pounds pressure on center stone. The precious
metals are especially hardened and this is accomplished by pressure
or by thermal treatment. This special treatment to the precious metal
results in the precious metal having a certain springiness which will
grip the diamond without the necessity of a bezel or claws. The
diamond is basically pressed by the girdle on each side by the ends
of the ring. The visual effect of the ring can be absolutely
stunning. Each metal end has a small groove called the 'seat' into
which a small section of the girdle fits. |

Tension
Products Safety:
Tension set ring is (rings & settings) is considered to be safe
or safer than four prong settings (prongs can get loose over years).
As far as the diamond being more prone to nicking, or breakage, this
is not true. Diamond can be damaged in any setting. The tension set
mountings can actually cover more of the girdle than other types of
settings, thus resulting in a little better protection than some
prong settings. Unlike a prong, which can be bent back by only a
little bit of pressure against a hard point or surface or tool, the
tension sets are held over a much wider area of the girdle, and the
entire setting must be sprung away from the stone to actually remove
it. Since the whole point of such settings is that the metal is
highly conditioned to a spring condition, slight deflections that
might, in unusual situations, spring the setting apart a bit, don't
hurt since the setting instantly springs right back to it's original
position due to it's being engineered as a compression spring. It
does not need to actually exert much force on the gem. |

surface or tool, the tension sets are held over a much wider area of

back to it's original position due to it's being engineered as a

the gem. Some people are under the impression that tension set ring
(rings & settings) cannot be resized. Tension set rings can
easily be sized one ring size up or down. For a tension set ring
(rings & settings) that need to be resized more than one ring
size, we can make a new tension set ring at an additional cost which
could range from $50 to $150. |

Tension Set
Concept | Unique Style | Enhances Diamond's Brilliance: Tension
set products (rings & settings) are a unique means of showing
and selling loose diamonds. Ingenious setting which exposes the
majority of the diamond to the surrounding light. Prong setting can
over-power the stone and make it look heavy. A tension-set diamond is
pressure held at its girdle within a gap created at the two pressing
ends of a ring. The result is a stunning visual and aesthetic effect
which exposes much of the diamond to the eye, and renders it to
appear to almost hover in midair. Tension set product (rings &
settings) is the very best method of showing a stones brilliance. It
can enhance the color of the diamond by as much as two grades. There
have been no known diamond losses due to tension set design. |
