Diamond is the hardest natural material. That is quite a title: diamonds score a 10 on the Mohs hardness scale, a scale that ranges from 1, which is the softest and includes materials like talc, all the way to a 10. It is the molecular structure of diamonds that makes them so hard, with the carbon atoms arranged in a strong, tetrahedral structure, making diamond the least compressible and stiffest substance. In fact, diamonds can only be scratched or damaged by other diamonds; it this natural hardness which makes diamond ideal for polishing tools and industrial cutting, such as military materials like airplane components and armour. So, at least, if you decide to buy a diamond engagement ring, you wont have to worry about it getting scratched. However, although diamond is very hard, it is relatively brittle. As a result it splits along its crystal cleavage planes when receiving a certain impact.
Natural sources for rubies produce the finest examples of the stone; the main areas for mining rubies include Burma (now called Myanmar), Thailand, Cambodia and in smaller quantities Afghanistan.
When white gold was first produced in the early 1900s, it was alloyed with nickel, palladium, platinum or zinc to imitate platinum, but as a much more affordable option. At this point white gold engagement rings were not plated with rhodium as gold was whiter than it often is today. Since manufacturers know that the gold will be plated, they use less white alloy because palladium and platinum are expensive, nickel is restricted, and a manganese alloy presents difficulties when working the metal. If you like the more natural lustre of white gold, it is possible to find designers who create jewellery using a whiter alloy.
Maybe your bride-to-be loves history and has a soft spot for old things. The right choice then would be an antique engagement ring or a vintage engagement ring. These rings will take her back to the timeless and romantic decades between 1910 to 1940. They whisper of romantic getaways and beauty that will last forever. These are a little on the higher side as they are considered treasures. Many of these rings cost anywhere from $1000 dollars and upwards. If your sweetheart is not a lover of all things antique but does appreciate the design that goes into jewelry of this kind, why not settle for a vintage style engagement ring or an antique style engagement ring. Some of these designs include the halo design, the pave setting, the Milgrain design and the side setting. Lets look at each of these in detail. With the halo design there will be a central stone surrounded by little diamonds, giving the look of a halo. The pave settings are similar to the pavement but much more romantic. The diamonds are closely set together, leading towards the central diamond. The Milgrain design gives off more of an antique look because of its beaded quality. Last but not least is the side setting design. This has the diamonds detailed very intricately on the side giving the beautiful effect of a timeless finish.
