Bracelet are popular jewellery item
At Blue Nile, all our platinum bracelets are made of platinum. Blue Nile gold bracelets are made from the finest 18k. This provides a perfect match of beauty and durability. Pure 24k gold is soft and easily bent while 14k gold is mixed with other metals that potentially dull the color of your gold bracelet.
Our silver bracelets are crafted from the highest-quality pure sterling silver, and all are inspected for a fineness mark to ensure quality. Our sterling silver charm bracelets and charms are created exclusively for Blue Nile. Our high-quality charms feature a custom lobster claw, designed to precisely fit either of our unique bracelets.
A gemstone is a stone that is beautiful
A gemstone is a stone that is beautiful, rare, and durable resistant to abrasion. Today, finer gemstone specimens are available to the average person than at any time in history.
Nowadays such a distinction is no longer made by the trade. Rare or unusual gemstones, generally meant to include those gemstones which occur so infrequently in gem quality that they are scarcely known except to connoisseurs, include andalusite, cassiterite and bixbite. Some minerals can be very beautiful, but they may be too soft and will scratch easily (such as the mineral fluorite). Fluorite is extremely colorful and pretty but has a hardness of only 4 on the hardness scale and has four perfect cleavage directions, which makes it only an oddity as a cut gem.
A diamond is a form of carbon
A diamond is a form of carbon that was created deep within the core of the earth more than 3 billion years ago and brought to the surface by volcanic eruption. In diamond, each carbon atom is bonded to four other carbon atoms in a tetrahedral structure, like a pyramid.
Each link or bond is the same length, and the tetrahedral formation is therefore completely regular. Theoretically a perfect diamond crystal could be composed of one giant molecule of carbon. After the magma cooled, it solidified into kimberlite, where the precious rough diamond is still found today. It is the strength and regularity of this bonding which makes diamond very hard, non-volatile and resistant to chemical attack.
