1. The Journey of Aquamarine: From Earth's Depths to Ocean-Blue Brilliance
The history of Aquamarine dates back millions of years, formed under extreme heat and pressure and the correct chemical environments deep within the earth's crust to slowly produce a beautiful blue crystal and one of the most cherished gemstone varieties today. A member of the Beryl family of gemstones, Aquamarine derives its beautiful blue color from its trace content of iron within its structure. Aquamarine is primarily sourced in Brazil, Madagascar, Nigeria and Mozambique with Brazilian Aquamarine often being the clearest and brightest colored.
Natural Aquamarine's are mined from pegmatite rock formations by means of both modern and traditional methods. Once removed from the earth, the raw Aquamarine crystals are sorted according to size, clarity and color, they would not appear anywhere near as dazzling as a finished polished gemstone that would be seen displayed in a jewelry display cabinet. A skilled gemologist or buyer would then examine each crystal and ascertain its value and whether or not it would be suitable for fine jewelry.
Once extracted, a Natural Aquamarine can now begin its transformation into a sparkling gemstone during the cutting and polishing stage. Each crystal is expertly analyzed by a lapidary before its potential is determined and an ideal cut is selected that will yield maximum brilliancy while maintaining as much weight as possible from the original crystal. Gemstone cutting transforms raw crystals into radiant gems through the meticulous faceting process. Aquamarine's great clarity makes it suitable for cutting in many different shapes including oval, emerald cut, cushion cut and pear cut.
Before a natural Aquamarine is available on the open market, professional grading and certification is commonly carried out giving peace of mind to the buyer regarding the gemstone's genuineness, quality and natural origin. Once declared ready it will be supplied to a designer for its insertion into a spectacular fine gemstone jewelry piece, a pendant, ring or pair of earrings.
The lasting popularity of Aquamarine is undoubtedly derived from both its beauty and its symbolism. Long associated with the calming sea, clarity and peacefulness it has been worn by royalty, seafarers and gemstone collectors for centuries.
