| Aquamarine |  Aquamarine (the Latin word aqua marinā implies "water of the sea") is a gemstone-worth translucent type of beryl, having a soft blue or turquoise color, imaginable of the tinge of seawater. Colors may vary and there are yellow beryl, rose pink beryl, and white beryl.
Aquamarine is a beryl with a six-sided crystal composition; it is a beryllium aluminium silicate substance. Its gravity is estimated at level from 2.68 to 2.74 and Mohs scale hardness is accounted at the level of from 7.5 to 8. Aquamarine physically is on the bottom of the gravity line, on the whole at less than 2.7. The pink kind demonstrates a high gravity of approximately 2.8. Index of refraction ranges around 1.57 to 1.58.
Modern Designers Adore Aquamarine
There is almost no other gemstone in contemporary jewel designing which is sophisticated in such a range of techniques as aquamarine. It doesn’t matter if it is designed as a pure, translucent gemstone in the traditional step faceting, or artistically ground in a more up to date style; it is for all time intriguingly stunning. Unfaceted too, or with lots of impurities which can be taken into play by the stylist in the way in which the stone is ground, it could be improved to manufacture the most gorgeous designs. Stylists name it their preferred gem. Over and over they astonish the world with a new, fresh imaginative faceting, and when they are starting on something new, aquamarine is a gemstone that they for the most part are willing to work with. Indisputable, this inspired style faceting has contributed to the great fame of the gemstone. The luminous color of aquamarine makes it easy to find impurities. Consequently, aquamarine should at all times be of the greatest probable clearness. Then again, especially delightful effects can sometimes be realized in the way the gemstone is faceted by taking the impurities into ornament.

In this fashion, each aquamarine is considered as a exceptional sample, whose miraculous magnetism no woman can stand firm.
PHYSICAL CHARACTERISTICS:
• Color is diverse and consists of blue to blue-green, yellow, virescent-gold, neutral and pink.
• Luster is glassy.
• Diaphaneity: Crystals are clear to semi-transparent.
• Crystal System is hexagonal; 6/m 2/m 2/m
• Crystal Habits obviously comprise the hexagonal prism with pincoid endings. The endings are frequently changed by many different pyramidal faces which can occasionally create a rounded ending in the irregular form.
• Cleavage is imperfect in one direction (basal).
• Fracture is conchoidal.
• Hardness is estimated at 7.5 - 8.
• Specific Gravity is about 2.6 - 2.9 (average)
• Special Characteristics: Faces on big crystals are frequently scratched, grooved along the stone and irregular.
• Related Minerals comprise micas, quartz, euclase, calcite, tourmalines and some orthoclase.
• Important Occurrences: aquamarine occurs in Brazil, Russia and Pakistan; other beryls are discovered in California, Brazil, Africa, and many other localities.
• Major Field Signs are crystal habit, absence of fine cleavage, hardness and color.
