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.
- 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.
- Carat - The Larger a Diamond, the More Rare. Larger diamonds are found relatively infrequently in nature, which places them at the rarest level of the Diamond Quality Pyramid. What also makes a bigger diamond so desirable is that it shows off a stone's fine color and cut, and therefore its brilliance, to its best advantage.
- The More Pure the Color in a Diamond, the More Rare. Diamonds are graded by color, starting at D and continuing through the alphabet. Truly colorless stones, graded D, treasured for their rarity and value, are highest on the Diamond Quality Pyramid.
- 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.

About Gold
- Reflecting the properties of the precious metal itself, a gift of gold has always been the symbol of lasting love and devotion.
- 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.
- Of all the world's precious metals, only Gold combines the four basic characteristics that make it a universally and eternally treasured possession.
- 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.
- 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.
- 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.

About Gemstones
- The majority of gemstones are crystallized minerals. (Important exceptions: pearl and coral are animal origin; jet and amber are vegetable.)
- Sapphire, a variety of corundum, comes in all colors except red (the red variety being known as ruby), but is especially popular in deep blue.
- 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.
- 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.
