About Diamonds
- 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.
- Fancy diamonds -- in well defined colors that include red, pink, blue, green and canary yellow -- are highly prized and particularly rare.
- While larger diamonds are highly prized, diamonds of equal size may vary widely in value and brilliance, depending on their qualities of clarity, cut, and color.
- 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.
- The Diamonds Quality Pyramid is a framework to help you compare diamonds. While all diamonds are precious, those closest to the top of the pyramid -- possessing the best combination of cut, clarity, carat weight and color -- are the earth's rarest, most valuable and most beautiful to the eye.

About Gold
- 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.
- When buying gold jewelry, always look for a Karat mark such as 14k, 18k stamped somewhere on each piece to ensure yours is real gold. Europeans sometimes stamp their gold pieces with 500 representing 14k or 750 representing 18k.
- Of all the world's precious metals, only Gold combines the four basic characteristics that make it a universally and eternally treasured possession.
- Ease of Workability - Gold has the best working qualities of any metal, thereby making it the ideal precious metal for fine jewelry whose designs are meant to reflect and appeal to so many different personalities.
- 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
- A cultured pearl is a pearl formed by an oyster, composed of concentric layers of a crystalline substance called nacre deposited around an irritant placed in the oyster's body by man. Natural pearls are formed by deposits of nacre around an irritant which accidentally lodges within the body of an oyster.
- 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.
- Emerald is one of the most highly-prized of all the gems. The name comes from the Greek "smaragdos" which means green stone. The most prized is the pure grass green.
- Amethyst is a variety of quartz, and comes in pale lilac to rich, deep purple shades.
