| Choosing
A Diamond Ring
Normally
wear in order to feel comfortable.
Does
the inside of the ring feel rough and scratchy? If the metal
band does, it can smoothed down by polishing. Occasionally,
diamonds are set too low and the pointed bottoms prick your
finger. If this is the case, it would probably be easier to
choose am u ring than to correct the problem.
Does
the ring feel too bulky and heavy, or are you able to forget
that you're wearing it ?.
Once you have decided that a ring is attractive, suitable,
and comfortable, you n ii-, wonder if it's worth the price.
To determine this, you need to know the factors which affect
the cost of mountings, and to understand these factors you
should know the following terms.
Cast Refers to mountings made by thrusting molten metal into
plaster of Paris type molds with a centrifugal force or vacuum.
The mold is made by pouring the plaster of Paris type material
over a wax model of the desired ring. The wax is then melted,
leaving a ring mold Casting is a relatively fast process that
allows many identical articles to be made from a single design,
which is why most jewelry is cast.
Cast
mountings are relatively porous and the relatively porous
and therefore less durable than those that are handmade or
die-struck.
Die-struck
Refers to mountings formed with metal parts mechanically punched
out of compressed sheet metal with dies (forms or molds).
Since this ¬metal is harder and more compact than cast
metal, it is less subject to wear. Die-struck mountings generally
have simple, standard ddesigns and are produced in large quantities.
Hand-fabricated Refers to mountings made by sawing, filing,
and shaping metal parts and wire by hand and then soldering
them together. A hand ¬fabricated mounting is literally
one of a kind and takes a lot of time to make.
Custom-made
Made for special order instead of mass-produced. Generally,
custom ¬made refers to rings requiring handwork or individual
casting and specially-made molds. It can also refer to rings
formed by soldering pre-fabricated metal parts together to
form a design chosen by a customer. If a customer has a ring
modified by changing the stones, it is usually called a remount.
