YELLOW GOLD: Gold is a precious metal with a natural yellow color. It is quite soft and often alloyed with other metals to increase its strength. The purity of the metal is indicated by a unit called a "karat," with 24kt having the highest percentage of natural gold.

TEXTURED: A unique and varying finish with a tactile surface applied through various techniques, both by hand and with machinery.

CARNELIAN: A brownish-red mineral, carnelian has been used for centuries to make engraved gems and signet rings, intaglios and especially seal rings, because hot wax does not adhere to it. Its name comes from the Latin word for cherry, since the lush red color of the carnelian so resembles the vivid red fruit.

CARVED: When a gemstone is cut so that the outline or surface takes the form or likeness of a specific image or pattern.
