About Diamonds
- The Better Cut a Diamond, the More Brilliant. A well cut or faceted diamond, regardless of its shape, scintillates with fire and light -- offering the greatest brilliance and value.
- Fancy diamonds -- in well defined colors that include red, pink, blue, green and canary yellow -- are highly prized and particularly rare.
- 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.
- Virtually all natural diamonds contain identifying characteristics, yet many are invisible to the naked eye. Under the scrutiny of a jeweler's 10x-magnifying loupe or microscope, natural phenomena -- called inclusions -- may be seen. These are nature's birthmarks, and they may look like tiny crystals, clouds, or feathers.
- 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.

About Gold
- Gold lasts, and lasts. Since it does not rust, tarnish or corrode, gold virtually lasts forever. An example of this incredible durability is witnessed in the gold coins found in sunken galleons centuries-old - they're as bright and shiny as the day they were cast!
- Gold's natural beauty is further enhanced by the soft and exquisite shades of color achieved by combining it with small amounts of other special metals.
- 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 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.

About Gemstones
- Most people think of topaz as a transparent golden yellow gemstone. However, this gemstone occurs colorless as well as orange-yellow, red, honey-brown (dark sherry), light green, blue and pink.
- Colors in turquoise range from sky blue (most desirable color) to blue green and apple green.
- Peridot should be a lively lime green, without a brownish or olive cast.
- 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.
