About Diamonds
- 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.
- 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.
- 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.
- 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.

About Gold
- 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.
- 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.
- Of all the world's precious metals, only Gold combines the four basic characteristics that make it a universally and eternally treasured possession.
- 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.
- 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.

- 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.
- There are several factors that determine the value (and price) of a gemstone: color, cut, clarity and carat weight.
- The majority of gemstones are crystallized minerals. (Important exceptions: pearl and coral are animal origin; jet and amber are vegetable.)
- Colors in turquoise range from sky blue (most desirable color) to blue green and apple green.
