Jewelry Education

Diamond Education

Before purchasing a diamond and/or diamond jewelry, it is important to know the facts. Diamonds have many characteristics that can affect its value and add to its uniqueness. In our education brief, Pompeii3.com will give you all the information you will need to make an educated purchasing decision. However, if you should have any more questions, please contact us at 847-367-7022 or email us at support@pompeii3.com.

History of Diamonds

The word, diamond, comes from the Greek word, adámas, meaning “unbreakable.” This meaning, “unbreakable” led to it being the symbol of unbreakable love. A diamond is formed in the Earth’s mantle under high-pressure and high-temperature conditions and brought near to the Earth’s surface by volcanic eruption by a magma which cools into igneous rocks. First recognized in India as religious icons, diamonds have been a symbol of love and wealth for centuries. Its use as the preferred gem in engagement or wedding rings is suited for every day wear because of its durability. Unlike many other gems, it is the hardest gemstone and it maintains its polish extremely well.

Diamond Cut

Facet Parts Diamonds come in many shapes with the round brilliant cut being the most popular. The cut of a diamond is related to its sparkle, the better cut the diamond, the more sparkle it will have. Cut is considered to be the most crucial of the 4C’s as all the facets have to work in harmony to create the greatest brilliance, or sparkle, which is what makes diamonds so desirable. A well cut diamond can reflect up to 90% of the light from above, a fair or poor cut diamond will only reflect about 40% of the light. The proportions of the cut can have an effect on how the light is reflected. A shallow cut diamond (the bottom half lacks depth) will reflect light down, a diamond cut too deep will reflect light out the side. The most prized and valuable cut diamond is cut ideal so the light is reflected out the top.

Light Handling Properties of a Diamond

Cut so that the light is reflected back through the top of the stone
light
Too Deep; allowing light to escape through side
light
Too Shallow; allowing light to escape from the bottom

Diamonds are fashioned into a number of shapes, depending on the nature of the rough stone. The seven most popular shapes are princess, marquise, pear, emerald, oval, heart and round (also called brilliant). The round, brilliant cut is the most popular shape.

Diamond Color

A diamond’s color can either detract from or enhance its value; a chemically pure and structurally perfect diamond is transparent with no hue or color. Color in diamonds can be affected by chemical impurities and/or structural defects in the crystal lattice. When a more yellow tint or color is visible in a diamond, the price is discounted while the more white the diamond, the higher the price. Diamonds are graded on the “D” to “Z” scale determined by the Gemological Institute. A Diamond with a “D” rating means it is blue white and is the most pure white found in a diamond. The “Z” rating is given to diamonds with a yellow tint. Diamonds that receive the “D” rating are higher in price. However, intense pink or blue diamonds can be dramatically more valuable due to their rarity.

Diamond Clarity

The clarity of a diamond relates to its internal characteristics that affect the overall appearance of the diamond. Inclusions, inside flaws in a diamond, and blemishes, defects on the outside of a diamond, are less desirable. These inclusions do not affect the diamonds’ performance or structural integrity but large clouds can affect its ability to transmit and scatter light. Some minor inclusions can be useful, as they can be used to identify each individual diamond, like a fingerprint. Most inclusions are undetected to the naked eye. However, diamonds without inclusions or Flawless graded diamonds are the most desirable and fetch the highest prices.

Diamond Carat

A carat is the unit of measurement used to weigh diamonds, which determines the size of the diamond; the diamonds width increases with the number of carats. One carat is equal to 0.2 grams, or 200 milligrams. The carat weight of a diamond plays a big part in the price. Diamond prices increase significantly at the half- and full-carat weights. Diamonds just below these weights cost significantly less. Larger diamonds are much more rare than their smaller counterparts making price increase significantly with large jumps in carat weight. For example, a two-carat diamond will cost more than two one-carat diamonds of equal quality.

Gold

Gold is a transition metal and with exception of the noble gases, gold is the least reactive chemical element. Since long before recorded history, gold has been a valuable and highly sought-after precious metal for coinage, jewelry and other arts. Historically, gold was seen as having mystical powers, and was thought to be the metal of the sun for its natural beauty. Today, it is one of the most valued and cherished precious metals because its physical properties are unparalleled for use in fine jewelry. It is a shiny and dense metal but also so soft it is the most malleable and ductile metal. The purest gold has intense luster and a bright yellow color. However, gold also comes in white gold and rose gold.

The color of gold is determined by the density of loosely bound electrons. Rose gold can be created by the addition of various amounts of copper and silver whereas white gold is created by adding palladium or nickel.

Gold Karat Weight

Gold is measured in Karats, not to be confused with carat diamond weight. Karat is the term used to indicate the purity of the gold, with 24 karats being pure gold and too soft to be used in jewelry. Mixed with alloy for strength, the most common purity of gold used in jewelry is 14K or 18K, which is 75% purity. Karat weight also determines the value of gold jewelry, the more pure the gold, the higher the price.

Platinum

Platinum ranks among the rarest of metals and exhibits a remarkable resistance to corrosion and as such is considered a noble metal. In the 18th century, platinum began to appear in the jewelry of western Europe and soon became the metal of royalty. Platinum is used in jewelry at 90-95% purity, unlike gold, which doesn't work well in its purest form. However, it is like gold in that it is tarnish and rust resistant. Only a few hundred tones are produced annually, thus making it a scarce material and highly valuable.

Different Setting Types

Setting refers to a specific technique in securing a precious stone to a piece of jewelry.

Jewelry Education
Prong Setting

Prong settings are used to raise the stone up from the mounting allowing light to enter the various facets.

Jewelry Education
Common Prong Setting

A Common Prong Setting shares prongs which provides a nice clean look and allows the stones to be set closer together.

Jewelry Education
Channel Setting

A Channel is carved out of the metal and stones are placed inside the channel. A hole is placed under each stone allowing light to enter the facets increasing the fire and brilliance.

Jewelry Education
Bar Setting

Bar setting refers to the metal bars that separate gemstones along the individual precious metal. The bars provide tension locking the specific gemstone in place.

Jewelry Education
Pave Setting

Pave setting refers to multiple gemstones positioned extremely close together providing a brilliant surface.

Jewelry Education
Bezel Setting

Gemstones are secured with a rim made of precious metal (Gold or Platinum).
