N: The “N” symbol appears on the chart only for natural stones which are not currently known to be enhanced; however, the “N” symbol can also be used for other natural gemstones in the event that a gemstone has received no enhancement and the seller will provide a guarantee that there has been none.

E: The “E” symbol indicates that a gemstone has undergone its traditional enhancement process.

Because of the rarity of naturally occurring pearls, a process of cultivating pearls was introduced in the early 1900s. In this process, a small bead of polished shell is inserted into an oyster or mollusk to act as an irritant and produce a pearl, which can take up to 24 months. These pearls are referred to as cultured pearls. Pearls are classically elegant and never go out of style.

Types of pearls

Akoya-These pearls were the first type of pearl to be cultured. Japan and China are the main producers of these pearls. They are consistently round, which makes them perfect for strands. Colors range from white to cream, though some can be gray or black.

Freshwater-The freshwater pearl is usually slightly less round, smaller in size, and possesses less luster than other varieties of saltwater pearls. These pearls are usually cultivated in China and provide a value-priced option.

Mabé-(MAH bay) Instead of growing inside an oyster or mollusk like other pearls, the mabé pearl actually grows against the shell of the oyster, creating a dome-shaped pearl. This pearl is harvested, then assembled. The nucleus is removed and replaced by resin, while mother-of-pearl is used to cover the flat back. Mabés traditionally have high luster and lower prices than round pearls.

South Sea-These pearls are cultured in the northern waters of Australia, Indonesia, and the Philippines. These pearls are considerably larger than akoya pearls and much more sensitive during the cultivation process. South Sea pearls are naturally white, cream, or golden in color.

Tahitian-These pearls are slightly smaller than the South Sea pearl, but are also sensitive during the cultivation process. The colors of black, silver, and gray occur naturally and they are cultured in Tahiti as their name implies.

Ring Sizer Instructions:

In order to determine your ring size, we ask you to use the two different ways shown in the document. You may use just one, but we recommend using both in order to cross check the results and minimize the possibility of making a mistake.

First, using the sizer strip you have cut out, place it around the finger on which you wish to wear your ring. Make the numbers face outward and pull the sizer through the slit over the largest part of your finger (possibly your knuckle).

Be sure to pull it tightly for a more accurate sizing. Look at the slit and write down the number that lines up with it.

Second, use your own ring that fits the finger on which you wish to wear your new ring. Place the ring onto the circular sizers. Whichever circle your ring fits most closely with will be your ring size. If it falls in between sizes, go with the larger one.

The number results for both should match. If they do not, we suggest that you use the larger one to insure that you will be able to wear it when you receive it. Please note that your fingers will always measure smallest when it is cold, so you will not want to measure when they are cold.

Buying a diamond is often a very personal experience. Diamonds can be bought to signify love, significant accomplishments, or milestones in your life or that of a gift's recipient. Unlike when you buy clothing, electronics, or cars, the features of a diamond may not seem quite so obvious to you. At COMPANY NAME HERE, we would like to change that. The more you know about your diamond jewelry, the more confident you will feel when making your diamond jewelry choices. Take a moment to learn more about the 4Cs and find out how they play a an important role in making your diamond jewelry unique.

Shape
The shape of the diamond is often confused with the cut. COMPANY NAME HERE carries diamonds that are round, princess, oval, pear, and marquise. Choose the shape that you like based on your style and you cannot go wrong. (See Figure below)

Cut
The cut of a diamond determines its brilliance or sparkle. Each shape will be cut differently. Before a diamond is cut, the location of inclusions and flaws, the natural coloration, and the original shape of the rough stone are studied extensively. The stone facets are then mapped out and cut in a way that maximizes size, shape, and clarity. For optimal light performance, you will want a diamond that is cut neither too shallow nor too deep, like the stones that COMPANY NAME HERE offers. (See Figure below)

 

Color
Diamonds are graded based on the amount of color they do or do not possess. The scale runs from D (colorless) to Z (light yellow). An absolutely colorless diamond is rare and therefore very valuable. At COMPANY NAME HERE, our jewelry contains near colorless (G-J) diamonds because we feel that they give you the best overall value. (See Figure below)

 

Clarity
A diamond is distinguished by its natural characteristics, just as a person would be noted for her blue eyes or his brown hair. Notated as a diamond's clarity, these characteristics can be present on the surface (blemishes) or within the stone (inclusions). The clarity is judged by the number and types of these characteristics and is designated using a scale that runs from Fl, defined as flawless, to I3, defined as inclusions visible with the naked eye. A flawless diamond is truly rare. (See Figure below)

 

Carat Weight
The unit of measure used for the weight of a diamond is the carat. As a matter of reference, a carat is equivalent to .2 grams or .007 of an ounce. Carat weight can also be divided further by using points. There are 100 points in one carat. So a 1/4 (.25) carat stone can also be expressed as 25 points and mean exactly the same thing. When comparing two diamonds, please note that just because one is twice the carat weight of the other does not mean that it will appear to be twice the size.

 

THE 4 C's OF GEMSTONES

---

Buying a gemstone is often a very different experience than buying a diamond. Gemstones are bought based on favorite colors, wardrobe matches, personality, and fashion trends. While gemstones are judged using the 4Cs, just as diamonds do, each is judged separately. For example, a sapphire is compared to another sapphire, but wouldn't be compared to an emerald or aquamarine. Choose your gemstone jewelry based on your personal preferences.

 

Shape
COMPANY NAME HERE sells a number of different shaped gemstone jewelry. Some of our most popular shapes include round, marquise, oval, pear, princess, and baguette.

 

Cut

Gems are cut in a variety of different ways. Transparent stones will often be cut with facets. Unlike diamonds, the facets are planned to maximize the color. Other stones like jade, opal, and onyx will be cut into a smooth domed shape known as a cabochon. While still other stones like cameos are intricately carved.

 

Color

Gemstone color is different from judging the color of a diamond. Every gemstone has a range of color that runs from light to dark and more vivid to less vivid, with a small range of color considered preferable. All of the families of color are represented by gems of different types.

Red Mozambique, Garnet, Ruby   Pink Rhodolite, Garnet, Pink Sapphire   Yellow Yellow Sapphire, Citrine   Green Bloodstone, Emerald, Jade, Peridot   Blue Aquamarine, Blue Chalcedony, Blue Spinel, Blue Zircon, Lapis, Blue Sapphire

Purple Amethyst, Tanzanite   White Akoya Pearl, Freshwater Pearl, Mabe Pearl, South Sea Pearl, White Spinel, White Topaz, Moissanite, Opal   Brown Smoky Quartz   Black/Gray Tahitian Pearl, Onyx

Clarity

Gems also have internal characteristics called inclusions. Some gemstones are known for having many inclusions like emerald or for having few inclusions like citrine. Each gemstone will be graded for clarity differently.

 

Carat Weight

Like diamonds, gemstones are measured using carats. A carat is equivalent to .2 grams or .007 of an ounce. Unlike diamonds, each gemstone has a different density which greatly contributes to the weight of the stone.

METAL TYPE

---

There are a variety of metals choices available for jewelry. Whether you like the allure of platinum or the range of options with the classic gold, you will find a number of stylish pieces, sometimes even combining the two metals. Today, alternative metals like sterling silver, titanium, and stainless steel give you additional options in look, strength, price, etc. Each choice has its own qualities, so base your choice on the ones that you value most.

 

Platinum
Platinum is generally 95% pure and does not tarnish or lose its rich white luster. Platinum is the heaviest of all the precious metals weighing approximately twice as much as karat gold. Its purity makes it hypoallergenic, perfect for people who are sensitive to the alloys used in gold. Platinum is also known for its strength and pliability, just one gram of platinum can drawn into a fine wire over one mile long.

 

Gold

Pure 24 karat gold is rarely used in jewelry because it is too soft for frequent wear. Gold is mixed with alloys like copper, silver, nickel, and zinc to give different colors, strength, and durability. Gold's purity is measured in karats, which indicate out of 24 parts how many parts are gold. For example, 18kt gold contains 18/24 gold and 6/24 alloy, while 14kt gold contains 14/24 gold and 10/24 alloy. Gold is traditionally seen in yellow and white colors, but can also be available in rose or green on occasion.

Sterling Silver
Sterling silver is usually 92.5% silver and 7.5% copper. Silver is much more plentiful than platinum or gold and is much less expensive. It takes on a much higher polish than any other metal, but it does tarnish. The tarnish can be removed, but silver requires much more care than other metals.

Titanium
Titanium is a light, strong, and corrosion-resistant metal. Titanium offers you seven times the strengh of platinum at about 1/3 of the weight. It is the hardest natural metal on earth and therefore offers more scratch resistance than gold or silver. In addition, titanium is also hypoallergenic. When ordering titanium rings, be extra sure about your ring size. The biggest drawback of titanium rings is that they cannot be sized by traditional ring sizing methods.

Stainless Steel
Stainless steel is a low cost alternative to traditional metals. It is naturally hypoallergenic and will not rust or tarnish. Stainless Steel will not break or bend under normal usage and is stronger than any other alloy.
