Whether gifting or treating yourself, know your gemstones. In this edition, Uncover the factors that determine diamond's quality.

Diamond is a precious gemstone and the only gem that is composed solely of carbon. Subtle variations in color, cut and clarity can cause significant differences in a diamond’s value. 


The less color the higher the grade.







The less included the diamond the higher the grade. Diamonds range from flawless (no inclusions at 10x magnification) to included with flaws visible to the naked eye (I3).






Cut represents the shape of the diamond. More importantly how a diamond is cut (proportions, symmetry, and polish) is a measure of how a diamond’s facets interact with light. It directly affects the brilliance that comes off the stone. Cut is rated from excellent (an even pattern of bright and dark areas) to poor.

Note: The number of facets affects the pattern of the reflections in a diamond rather than overall brightness. Diamonds with more facets have more numerous smaller reflections instead of fewer larger reflections. So, brightness is not a function of the number of facets.


One carat = 200 mg in weight. Generally heavier weight or larger carat size adds to a diamond's value, but all 4Cs - cut, clarity, color, and carat weight must be taken collectively to determine value, so do not rely solely on carat size. Note: Diamonds are sold by weight. 


While diamonds are very stable, sudden and extreme temperature changes are threatening to a diamond's stability. Those changes can cause thermal shock and create new fractures and cleavages or cause existing ones to spread.

Use warm water with a mild soap or detergent and a toothbrush to clean your diamond and dry with a lint free cloth. Harsh cleaning methods like powdered abrasive household cleansers, ultrasonic cleaners, and steam cleaners are not recommended for home use. 


Diamonds are the hardest material on Earth, and has been known since antiquity as a “Stone of Invincibility,” bringing victory, superior strength, fortitude and courage to its wearer. It is associated with lightning and fearlessness, and for its properties of protection. It is a symbol of wealth and manifesting abundance in one’s life, an amplifier of energies, goals and intent, and is highly effective in magnifying the vibrations of other crystals for healing. It is particularly beneficial set in gold and worn on the left arm.
