COLOR - Acquiring an Eye for Color Although most gem-quality diamonds when seen alone appear to be colorless to the untrained eye, there are subtle differences in shade. Color in diamonds results from traces of other elements which mix with carbon during the diamond's formation. Diamonds with no traces of body color are extremely rare. To determine a diamond's true color, the diamond is viewed table down under balanced white light. It is compared to diamonds in a "Master Set" whose colors have been predetermined by the Gemological Institute of America (GIA). Our diamonds are color graded using a master set and a special diamond light developed for color grading. The color grade is then assigned according to the diamond's color relative to the "Master Set". The grade is represented by a letter ranging from "D" (colorless) to "Z" (light yellow). The further down in the alphabet the diamond is, the more yellow it appears. A range of several grades makes up a descriptive color category.

  CLARITY - Distinguishing Clarity Most diamonds develop natural "inclusions" (crystals, feathers, etc.) during their formation deep within the earth. Diamond clarity is determined by the position, color, number, and/or nature and size of these inclusions. The fewer the inclusions, the rarer the diamond and the greater the value. Flawless and internally flawless diamonds are exceedingly rare. The term "flawless" is a highly restricted one. Under Federal Trade Commission rules, a diamond can only be deemed flawless when no internal or external imperfections are visible to a professional eye under 10-power magnification using a binocular microscope in good light. While inclusions may not affect the beauty of a diamond, they do affect its value and price.

  CARAT WEIGHT - Determining Carat Weight Of the 4 C's, carat weight is the simplest factor used to determine the value of a diamond. As with all precious gems, the weight of a diamond is expressed in carats. One carat equals one-fifth of a gram or 1/142 of an ounce. One carat is divided into 100 points, so a diamond weighing 3/4 carat has 75 points of 0.75 carats. As diamonds increase in value, their price per carat usually increases geometrically, not arithmetically. Thus, a two-carat diamond will usually be more than double the price of a one-carat diamond of the same quality. Diamonds are accurately weighed on a calibrated scale when they are loose, or free from any mounting.

CUT- It’s All in the Cut
The precision with which a diamond is cut is a critical factor in releasing its “fire” and “brilliance”. It is the cut that enables a diamond to make the best use of light. It is the only factor of the 4 C’s that man can control.

The facets, or prisms, of the diamond should be placed in exact geometric relation to each other. The culet, or point, should be in the exact center of the bottom of the diamond. Plus, the diamond needs to be well polished. This symmetry is crucial for light entering the diamond to be reflected back to your eye as brilliance.

Welcome to ‘Engagement Season’ When Nearly 40% of All Marriage Proposals Take Place

Welcome to “engagement season,” the magical time between Thanksgiving Day and Valentine’s Day when nearly 40% of all marriage proposals take place. According to WeddingWire’s 2018 Newlywed Report, Christmas Day is the most popular day of the year to pop the question, followed by Valentine’s Day, Christmas Eve, New Year’s Day and New Year’s Eve. Interestingly, the WeddingWire survey of 18,000 U.S. newlyweds married in 2017 reveals a dramatic spike in proposals during the month of December. Throughout the rest of the year, the distribution of proposals during each month ranges from 7% to 9%. But, in December, that number rises to 16%. Experts believe that the winter engagement phenomenon is attributed to two factors: the romantic nature of the season… and convenience. Suitors likely choose December to pop the question because they love the spirit of the holiday season. And, certainly, there’s no better time to propose than when all the family is in town to celebrate with the newly engaged couple. No matter when you are thinking of popping the question:  here is one of our top tips as you plan for that special occasion:  Enlist the help of a friend or family member to stealthily determine her ring… Read More
