About Diamonds
- A diamond's size is measured in carat weight, and each carat is equal to 100 points. A .75 carat diamond is the same as a 75-point diamond or a 3/4 carat stone.
- To establish a diamond's quality, jewelers examine each of the 4Cs -- cut, clarity, carat weight and color. The combination of the 4Cs determines the value of a particular diamond. For example, a colorless diamond is at the top of the Diamond Quality Pyramid in color ... but if it lacks clarity, is small, or not well cut, it will be of a lower value. The finest stones possess the rarest quality in each of the 4Cs, and are the most valuable.
- Clarity - The Purer a Diamond, the More Brilliant. The greater a diamond's clarity, the more brilliant, valuable and rare it is -- and the higher it is on the Diamond Quality Pyramid.
- Fancy diamonds -- in well defined colors that include red, pink, blue, green and canary yellow -- are highly prized and particularly rare.
- The number, color, type, size and position of surface and internal birthmarks affect a diamond's value. Major inclusions can interfere with the path of light that travels through a diamond, diminishing its brilliance and sparkle and therefore its value.
- Diamonds that are cut too deep or too shallow lose light that spills through the side or bottom. As a result, poorly cut stones will be less brilliant and beautiful -- and certainly less valuable -- than well cut diamonds higher on the Diamond Quality Pyramid.

About Gold
- Of all the world's precious metals, only Gold combines the four basic characteristics that make it a universally and eternally treasured possession.
- 18 karat gold is still very soft and not ideal for everyday wear, 14 karat gold is ideal for bridal jewelry as it is durable yet soft enough to allow the jeweler to create fancy settings such as channel and invisible settings.
- The naturally intense color and distinctive luster of gold combine to give this precious metal its unique and lasting beauty.
- Solid gold as it is found in nature is 24 karat gold. Unfortunately, solid gold is far too soft for use in most jewelry and requires additional metals, called alloys to be mixed in to make it suitable for jewelry manufacturing. 18 karat gold has 18 parts pure gold and 6 parts alloy, 14 karat has 14 parts pure gold and 10 parts alloy and 10 karat gold has 10 parts pure gold and 14 parts alloy.
- The desire to own gold dates back as far as the history of mankind itself. The place of gold has been extraordinary in every society. In earliest times, it assumed magical importance.
- Gold purity is measured by karats. Karat, sometimes represented as; "K" or "Kt." should not be confused with "Carat" which is the unit of measure for diamond and gemstone weight.

About Gemstones
- Colors in turquoise range from sky blue (most desirable color) to blue green and apple green.
- White opal has a white or light body color with flashes of many colors. Black opal has black, dark blue, dark green or gray body color with vivid flashes of color such as red, pin, and bright green.
- The ideal color of aquamarine is a refreshing pastel sea blue. Stones with a clear blue color without green or gray are generally the most valuable.
- The majority of gemstones are crystallized minerals. (Important exceptions: pearl and coral are animal origin; jet and amber are vegetable.)
