One of the key characteristics of a piece of jewelry is the type
of precious metal or metals
that are used to create the piece. European Creations uses two types of
metals to
create their jewelry: Gold and Platinum.
Gold is available in three primary colors: yellow, white and pink. The color
change is a
result of mixing the gold with alloy materials consisting of fine copper, fine
silver or nickel.
Yellow gold consists of a combination of gold, fine copper and fine
silver. White gold is
made of gold, fine silver and Nickel. Pink gold is comprised
of gold,
fine copper and a proportionately small amount of fine silver.
Gold is available in various purities, referred to as carats.
European Creations
uses all three colors of gold in three primary purities: 14, 18 or
20 carat.
14 karat gold consists of 58.5% gold and 41.5% alloy material.
18 karat gold consists of 75% gold and 25% alloy material.
20 karat gold consists of 90% gold and 10% alloy material.
Platinum is one of the most precious of all precious metals. Pure platinum is
very soft,
so the platinum used to make jewelry is comprised of 95% platinum
and 5 % iridium.
Platinum is a popular because it is very elegant.
A combination of the different colors of gold as well as gold and platinum precious
metals are often used in a single piece of jewelry to create a
beautiful effect.

The Four C's of Diamond Grading refers to the Cut, Color,
Clarity and Carat Weight
of a diamond. A combination of those four elements determines the overall
quality
of a diamond and therefore gauges its' value. |
|
Cut refers to how well a diamond is faceted, polished and
proportioned. The
"first look" characteristics that establish overall beauty and light reflection.
You can classify a diamond's cut into four categories: Very
Good to Excellent,
Good, Fair and Poor. Description of the classifications may be found below:
|
Very
Good to Excellent: |
|
Also called "Ideal" cut because these
diamonds exhibit a maximum combination of dispersion and brilliance. Premium in
value. |
|
|
Good: |
|
Proper balance of light dispersion (spectral
colors) and brilliance (white light). |
|
|
Fair: |
|
Moderate departures from preferred proportions.
Slight to moderate reduction in value. |
|
|
Poor: |
|
Substantial departures from standards leading to
major value reduction. |
|
|
|
Color is the amount of body color perceived by the trained eye
using proper
illumination of balanced white light and "master" diamonds of predetermined
color.
The color of a diamond can be referred to as colorless, near colorless, slightly tinted,
tinted and fancy color. The first four categories may be further refined by
assigning
a letter value to their color. The lower the letter, the higher the quality.
The values are as follows:
|
Colorless: |
|
D, E, F, |
|
|
Near Colorless: |
|
G, H, I, J |
|
|
Slightly Tinted: |
|
K, L, M |
|
|
Tinted: |
|
N, O, P, Q, ... to Z |
|
|
Fancy: |
|
|
|
|
|
Clarity refers collectively to the size, number, nature, color
and position of internal
characteristics visible to the trained eye at a magnification of 10X, as well as external
characteristics of the diamond. The Clarity of a diamond is classified into five
categories:
Internally Flawless, Very, Very Slightly Included, Very Slightly Included, Slightly
Included and
Imperfect. These five classifications are further refined into subcategories as
illustrated below:
|
Internally
Flawless: |
|
IF |
|
|
Very, Very
Slightly Included: |
|
V VS1, V VS2 |
|
|
Very Slightly
Included: |
|
VS1, VS2 |
|
|
Slightly
Included: |
|
SI1, SI2, SI3 |
|
|
Imperfect: |
|
I1, I2, I3 |
|
|
|
Also referred to as weight, a carat is a unit of measure equal
to 1/5 of one gram
(31 grams to the ounce), historically based on the weight of the carob seed. Carat
measurement is broken down into "points". A single carat consists of 100
points. |
