Amethyst
Amethyst has historically been the most prized gemstone in the quartz family. It is treasured for its purple hue, which can range in tone from light to dark.
Diamond
Diamond is a gemstone composed of chemically pure carbon, with a cubic crystal structure and manifesting extreme hardness resulting from the incredibly strong chemical bonds between the carbon atoms. Diamonds are valued for their brilliance, fire and beauty. Usually perceived to be a colorless gemstone, diamondsactually occur in every color including: yellow, green, pink, blue, purple and red. The value of a diamond is set by measuring and evaluating what in the diamond business is referred to as the four C's. – color, clarity, carat weight and cut. Diamond color is measured on a scale ranging from D to Z with D being the most colorless (and most desirable). Clarity has a series of designations that range from Flawless to Included representing the relative number, type and visibility of inclusions. Carat is a measure of weight where one carat is equivalent to 1/5 of a gram or 200 milligrams. Cut includes the shape of the finished diamond as well as a determination of how well the diamond was fashioned, its proportions and finishing details.
14ct
Because of the softness of pure (24k), it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other properties. Alloys with lower carat rating, typically 22k, 18k, 14k or 9k, contain higher percentages of copper or other base metals or silver or palladium in the alloy. Copper is the most commonly used base metal, yielding a redder color.
