The Amazing Variety of Tungsten Carbide

By Heather Pike

Both titanium and tungsten are considered "model metals" in the jewelry industry because they were not available to the consumer market as commodities until ten years ago. They have gained tremendous popularity since the introduction and become an integral part of the jewelry material spectrum. Due to the rather little exposure, many questions arise concerning titanium and tungsten when it comes to choosing jewelry. The followings are some points of consideration if you are seriously thinking about buying a titanium or tungsten wedding ring.

1. Hardness Titanium and tungsten are both known for the superior hardness over traditional metals such as gold, silver and platinum. One thing worth noting is that it is not the metals themselves in a pure form that possess the hardness, it is their alloys that do. Roughly speaking, the hardest form of tungsten carbide is harder than titanium alloys, and only under extreme circumstances, such as abrasion from diamonds, can it be damaged.

Engraving and resizing Titanium wedding rings can be engraved and resized. However, a tungsten carbide ring is too hard to be engraved or resized. Although engraving can be done, the letters will be very faint and difficult to read. So if you are buying to ring to engrave, get titanium rings.

Titanium is a strong metal but not resilient like tungsten carbide. Over time titanium rings will scratch and lose their polish thus needing to be refinished. Tungsten alone (not tungsten carbide) is also much like titanium. Without the carbide it does not gain its extreme hardness and durability.

Only when tungsten is combined with a carbon alloy is it transformed into tungsten carbide, the strongest of all metals. Tungsten carbide is also a heavier metal than titanium which is very lightweight, making it more durable and better looking. Titanium rings look great new, and usually are less expensive.

The Most Thoughtful & Outstanding Proposal Tips

By Brittany Childress

Cushion The cushion cut is an antique-style diamond cut that has recently come back into fashion. It is a cross between an Old Mine Cut (a deep cut with a high crown and large facets that was common in the late 19th and the early 20th centuries), and a modern oval cut. The cushion shaped diamond is squarish with rounded corners and sides.

This cutting style has a slightly softer brilliance compared with newer modern cuts. The cushion cut diamond has grown in popularity for its "old-world" femininity and elegant appeal. Length to width ratio Squarer-looking cushion cuts (Ratio of 1:1) tend to be prefered to more rectangular ones (Ratio of 1.2:1). Cushion cuts should not exceed a ratio of 1.2:1

Sawing Diamond sawing is a twentieth century innovation. Although cleaving may be efficient, it limits the cutter to shaping the stone according to its natural lines of cleavage. Sometimes, diamonds have to be cut against a cleavage plane (against the grain). The diamond saw, a lubricated circular steel blade allows cutters to go against the grain of the diamond without shattering it.

Asscher cut The Asscher cut is a variant of the emerald cut and provides a uniquely regal and elegant look to its wearer. Its art-deco styling combines old-world charm with modern cutting and faceting techniques to produce a dazzling example of brilliance. Length to width ratio Very Square Asscher cuts (Ratio of 1:1) are prefered to even slightly more rectangular looking ones. Asscher cuts should not exceed a ratio of 1.1:1.

Marquise shape The Marquise cut is boat shaped and is a variation of the round brilliant cut diamond. Marquise cuts are often chosen by woman who wish to display an independence of style. Its elongated form can create the illusion of longer, narrower fingers. Length to width ratio A marquise cut with a length to width ratio of approximately 2:1 is the norm. For those who prefer a rounder look, choose a ratio closer to 1.5:1. For those who prefer a more elongated shape, look for a ratio of 2.25:1

Mini Travel Guide To Varadero

By Jose Garces

Second to Havana City in tourist popularity Varadero beach resort area is the favourite beach destination in Cuba. It attracts tourism from all over the world but especially those from Europe and Canada looking for warm blue Caribbean Seas.

Getting there

There is and international airport in Varadero and a couple of international Marinas with immigration and customs check points. Most flights to Varadero are carried out by charter companies so if prefer to flight with schedule airlines instead to can fly to Havana and from there it will only take a couple of hours on the road to Varadero.

Moving around Varadero

There is a double-decker open-on-top bus that runs on a regular schedule from the tip of the peninsula to the town. You can also hire a car or even better a scooter which is more justifiable given the small size of the peninsula.

What to do in Varadero

A park in the middle of Varadero filled with birds, vendors, music and camel rides for the kids or and Excursion by Catamaran, snorkelling in a coral barrier reef or spending time swimming with dolphins seem to be the most popular of activities in Varadero. However there is much more to do and you can be advised by the tourist desk in your hotel reception.

Where to stay

This is a very subjective subject but in my modest opinion the best hotels in Varadero are Iberostar Varadero, Paradisus Princesa del Mar, Paradisus Varadero, Blau Varadero, Iberostar Tainos or any of the new Barcelo hotels.

Safety issues

Cuba in general, and Varadero in particular, are very safe places for travellers. Varadero is pretty strictly a tourist enclave, with limited access for locals, and routinely policed. Elsewhere in Cuba is much different. It is, however, arguably the safest country in the Caribbean for travelers, including single females. Use your common sense and you'll be fine.
