Frequently Asked Questions
What Does "Carat" Mean, and How Much Does One Actually Weigh?
The carat is divided into 100 points, so when a diamond is a quarter of a carat, for example, it means that it is 25 points.
What is the difference between white gold and yellow gold?
Gold comes from the earth a bright yellow color, therefore, white gold is naturally yellow too. In order to make the yellow less noticeable white property alloys are added to gold to help mask the yellow color. This is where karats of gold come into play.
Most people have heard of 10 karat (kt), 14kt, 18kt, 22kt, and 24kt gold here in the United States. For example, 14 karat gold is made up of 58.5% gold while the other 41.5% is made up of alloys. The most common alloys used in gold are copper, zinc, silver, palladium, and nickel. In white gold, the alloys used are typically the white property alloys silver, palladium, and nickel. These alloys are what make “white gold” white.
What does it mean to have your rings polished versus cleaned?
Polishing is a multi step process that uses a buffing wheel and multiple rouge compounds to remove tiny lines and scratches in a piece of jewelry. When a piece of jewelry has completed the polishing process it looks brand new. The usual reaction from a customer is that it looks like the day they bought it years ago.
What is a cleaning?
Cleaning, also known as a quick clean, is a service that utilizes an industrial strength ultrasonic and a high-pressured steamer. A quick clean takes no longer than five minutes to complete, providing your jewelry is relatively clean. It can take longer if the item has not been cleaned regularly or is extremely dirty. Therefore, you can be in a out in seconds and leave with your jewelry looking sparkly and new!
What is rhodium plating?
Rhodium plating is what makes white gold rings look bright white and shiny. Since white gold is not naturally white a jeweler will rhodium plate the piece, after polishing, to give it a bright white shiny finish again.
Since rhodium plating is not permanent, you will see it start to wear off over time. It is recommended that you have your jewelry polished and rhodium plated once approximately every twelve months.
What is the difference between a Diamond Certificate and an Appraisal?
A diamond certificate is a document issued by a gemological laboratory describing a loose diamond. A diamond certificate issues a grade indicating the physical properties of the diamond at the time of evaluation. A certificate is a document which retains its value over a long period of time, assuming the diamond does not chip or is not otherwise altered. An appraisal can be performed on a loose diamond, a mounted stone, or jewelry. If the stone is not loose, the physical properties are estimated using various estimation techniques. Most importantly, an appraisal indicates the dollar value of the piece under consideration. Appraisals are most often used for insurance purposes.
What are the 4 C’s?
The four C’s are Carat Weight, Cut, Color, and Clarity.
Carat is the weight of a gem. A carat equals 1/5 of one gram. Cut has two components to it. The shape of the stone and the way facets are positioned on the diamond. Color is actually looking for the absence of color or transparency. Clarity is inclusions and natural birthmarks of a diamond and is useful as identifying characteristics.

Diamonds are small, so the scale that is used to describe diamond weights uses very small units. A carat equals 1/5 of one gram. A carat is divided into 100 points. A diamond can be described as 75 points or 0.75 carats or 3/4 of a carat. It is a good practice to know the exact weight of a diamond when buying or selling.
The weight of a diamond is often thought of in terms of its size. If you know that you like the look of a 1 carat, for example, you can use this C as the starting point for your diamond search. Once you know the carat weight and your budget, you can adjust the quality of the diamond to fit. The photo above shows some common diamond carat weights and how they look in comparison to each other.
The Cut of a diamond has two main components. First, cut refers to the shape of the stone. Round, marquise, pear, oval, square, princess all describe the shape of the diamond. View the picture above to see examples of the most popular diamond shapes. There are many more shapes than we can list here and there are even variations on the common shapes with more facets or different facet patterns.
When you are choosing a diamond shape, keep in mind that different shapes have different light properties. Some shapes, like round, are especially good at returning light to the viewer which makes them sparkle more than other shapes. The emerald cut, for example, gives a classic look with big flashes of light but very little sparkle or fire. Ultimately, it’s up to you to pick the shape that you like best.
The second component to diamond cut is the way the facets are positioned on the diamond. When a diamond is cut to quality proportions (regardless of its shape) the maximum light is returned through the top of the stone giving a great light show. Cuts that are too shallow or too deep allow light to escape resulting in loss of brilliance.
Judging diamond color is actually looking for the absence of color or transparency (except fancy color). The color grading scale starts with D meaning totally colorless and moves down the alphabet subtly increasing in body color. As you can see from the picture, the difference between one or two color grades is quite small, but the price difference can be significant.
When deciding on a color for your diamond, you may choose to go down a color grade to allow you to buy a larger diamond for your budget. Or, you may want to get the whitest diamond possible. It’s all about discovering what’s most important to you. Also, keep in mind that the color of the metal you set your diamond in will have a big impact on how it appears. If a diamond is in the colorless range (D-F), and it’s set in yellow gold, it may appear to be much more yellow than it is.
Most diamonds contain inclusions. Inclusions are natural birthmarks and useful as identifying characteristics. Clarity grading is done with 10 power magnification. The number, size, type, and location of inclusions determine the grade. The fewer inclusions, the more valuable the diamond.
