Jewellery Shopping at Parties

"Home Parties offer a comfortable environment for jewellery shopping"

Those involved in the industry say the development of such parties are the root for the increased trend toward female self-purchasers and women's desire to socialize despite hectic schedules. Parties are a nice way to combine shopping with a social life.

In parties people don't feel obligated to buy, however they usually do.Women can try on the jewelry with their friends, and it gives them a great time out.

If you’re thinking of getting in on the party, here are a few tips to help get you started:

* Market to clients you already know: Suggest a jewelry home-party to a
new bride looking for something to share with her bridesmaids, or to a
female client you know has an active social circle.

* Keep inventory big, parties small: Part of the appeal of home-parties
is the ability for clients to try on jewelry in the comfort of their home,
minus feeling the pressure to buy. Keep parties small enough that everyone
can handle the jewelry without creating security issues.

* Build on your brand: Use jewelry parties as an opportunity to promote
your brand. Bring stylish displays and boxes for purchases, and make sure
everyone goes home with a catalog.

* Give it time: Don’t be discouraged by a slow start. As with any new
business venture, it may take time for the idea to catch on with consumers..

Gemstone Setting Types : Closed and Open Settings

Gemstone Setting Types : Closed and Open Settings

There are two basic types of gemstone settings: open settings and closed settings. Open settings are any type of setting that allows light to enter through the bottom of a faceted or transparent cabochon gemstone.

In a "closed setting" light can only enter the stone from the top. This type of setting is appropriate for opaque cabochon-cut stones and highly refractive faceted stones where light can enter through the crown and table of the stone and be reflected back to the observer from within.

Open Gem Setting Types

Prong Settings


Within the category of "open settings" there are several variations. The most common variety for faceted gemstones is a prong setting (below, left), with either 3 or 4 prongs that hold the stone in place. This type of setting exposes the maximum amount of light to the sides and bottom.


Carré setting

A Carré setting is where the stone is seated directly over a light well (above, right), and the stone is set by raising (hammering) four "spurs" with a "graver" tool.

Tension Settings

A "tension setting" uses the metal's natural tendency to "spring" back to its original position to hold the stone in place. The metal is spread apart, and the girdle of the stone is seated into small grooves in the inside surface of the metal. This type of setting requires special alloys of metal that are strong enough to create and withstand the necessary pressure to hold the stone firmly. Tension settings are only appropriate for very hard stones (Hardness of 9 to 10: diamond, ruby, sapphire, cz or moissanite).


Frustum Settings

A Frustum, or "Hollow Cone" setting is a conical or tapered setting constructed from sheet metal. The stone's pavilion rests against the inside of the cone and the outer edge of the cone's lip is bet over the girdle to secure the stone. A frustum setting can be open or closed.

Closed Gem Setting Types

Variations of the closed setting are the "bezel” setting, channel setting, cluster setting, Kundan setting, frustum setting, Pavé, and the seamless tube setting.

Bezel Settings

The oldest and most basic gemstone setting is the "Bezel". Used primarily to set cabochons, a vertical strip of metal is formed to encircle the stone, then soldered to a metal base. The stone is secured by pushing and bending the bezel towards the stone using a burnishing tool.


Channel settings

Channel settings are primarily used to set faceted gemstones that are straight-sided, or quadrilateral in shape (baguette or princess cut). The stones are aligned in a channel, sitting girdle-to-girdle. step-cut stones can rest on a track giving a "keystone" effect. Matching stones that are cut to a uniform size for use in channel settings are called "calibré-cut," as in "Eternity Rings."


Pavé Settings

A Pavé Setting is a tight grouping of identically sized stones laid across a flat, or convex surface, from the French word for "paved." The stones are held in place using three to six raised beads per stone.
