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.
- 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.
- 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.
- Diamonds categorized as internally flawless reveal no such inclusions. Flawless stones are at the peak of the Diamond Quality Pyramid and are treasured for their rarity and beauty. Diamonds with very, very small inclusions are graded as VVS1 or VVS2. The larger the inclusion, the lower the grade and the less rare the diamond. Inclusions that can be seen with the naked eye are graded I1 or I3.
- 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
- 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 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.
- 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.
- 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.
- 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!

About Gemstones
- Peridot should be a lively lime green, without a brownish or olive cast.
- Ruby is known as the "Lord of the Gems" because of its rarity and beauty. Derived from the Latin word "ruber", it simply means red. Ruby, like sapphire, is a variety of corundum and only exists as a true red in color.
- 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.
- 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.
- Of the more than 3,000 minerals found on earth, only a small percentage qualify as "gemstones" due to their beauty, durability, color and rarity.
