Well I dont know at all about diamonds, the only thing is the beauty of the stone. Yeah every time I saw the stone in movie, it must be a great stone with the lights and angle. It also known for its strength. It can be used to make a hole in almost everything such as steel etc. Talking about diamonds, I also find a term of carats. It could be similar with gold carats or so.
I thought that this term of carat will also equal with size of a diamond, & as carat size increases, so will the carat weight. Am I right? Well according to an article carat refers to the weight, yes the weight, not size, of a diamond and is equal to roughly 200 (two hundred) mg which is less than a percentage of one ounce. A carat can also be broken up into a hundred points. You get it? yes so simple, nothing to be doubt about. Again the weight, not the size!
What about when going to purchase this kind of stone. You may be tempted to purchase a stone that’s cut flatter so that you can have the appearance of a larger, or heavier stone. It’s a greedy, right? But a diamond that’s cut too flat will have too little brilliance and can look cloudy. Carat weight is important, but there’s no point to sacrificing other qualities that make a diamond special so you can say you have a two-carat stone. A beautiful one-carat diamond, with outstanding brilliance and scintillation is going to be the better choice, from both a personal standpoint and an investment standpoint. Yes thing about those things when you are about buying a diamond. Goodluck and enjoy the beauty of the stone.
Diamonds are among the hardest substances on earth; in fact they use diamonds and diamond dust to cut diamonds. Other gemstones are hard as well, but not nearly as hard as a diamond. Diamonds and other gemstones are measured by the Mohs scale. It runs from 10 (hardest) down to 1 (softest). It is somewhat arbitrary and not linear. The range from 9 to 10 is much greater than 8 to 9.Harder minerals of course tend to be more durable and will not scratch easily. They’re good choices for jewelry because of their ability to withstand changes in elements or the arbitrary scratch or knock. Talc, with a Mohs hardness of 1, is the softest mineral and can be scratched with a fingernail.
Quartz is the most common gem mineral (citrine and amethyst) and ranges at 7 and above. Rubies and sapphires are nearly as hard as diamonds, with a scale of 9 on the Moh’s scale.
People mistakenly think diamonds are indestructible and this is not true! Pliny the Elder in his Natural History stated that “these stones are tested upon the anvil, and will resist the blow to such an extent as to make the iron rebound and the very anvil split asunder.” If you tried that, however, you would more likely shatter the diamond, rather than the anvil!
Many diamonds are cut to prevent accidental nicks, scratches and breaks. Except for the Princess cut, which is a square-cut diamond with pronounced corners, most corners on angular diamonds are rounded. A protruding point of a square or rectangular diamond could inadvertently be knocked against a surface and chip or scratch.
Your diamond should be protected in a soft, velvet-lined case if you’re not wearing it. Have the setting checked periodically and have the stone examined by a professional. Your diamond is not only an investment in money, but an investment in yourself or your relationship and is worth the small amount of extra care it takes to preserve it forever!
Diamonds are durable and strong, but should be cared for as though they were fine breakable china or more fragile gems. They can chip or scratch if you’re not careful, and they can get quite dirty with oils from your skin and cosmetics, hair sprays or perfumes.
There are several ways to clean and store your diamonds. You can clean a diamond pretty quickly with a commercial jewelry cleaner that you either dip your jewelry in or soak them in a tub that gives it an ultrasound bath. Cold water and ammonia also work very well to dissolve oils that accumulate on your stones.
You can use a soft brush like an eyebrow brush to clean in between the prongs of the setting. Hold the diamonds by their settings and don’t touch the stones. If you’re cleaning them in the bathroom, be sure to close the stopper on the sink! You don’t want to go fishing in the plumbing for your valuable jewelry!
We’ve also used a mild toothpaste and soft toothbrush to clean gemstones. Rinse them under cold water, also using a soft brush to get any toothpaste particles from the gaps in between the stones and the setting. Some experts don’t recommend this and there is risk of scratching the stone, so if you choose this method, make sure it’s a low-abrasive. The best solution really is a commercial preparation or ammonia and water.
Rinse the jewelry in a tea infuser or under running water and dry it on a lint-free surface or towel. When you put your jewelry away, put it in a soft, velvet-lined box. Keep rings separate and don’t lump them in with all your other jewelry, to help protect the setting and the stones.
When you travel with your jewelry, make sure it’s in a soft, lined jewelry roll or a case specially designed for jewelry. Even if you wear your engagement and wedding rings all the time, take care of them. Don’t wear them if you’re using harsh cleaning chemicals or solutions or doing work that might cause them to knock against furniture or walls.
The cut of a diamond refers to the way the stone is shaped and polished, how the facets are arranged and how deep or shallow it’s cut. There are various cuts of diamonds that refer to that, many of them patented. Both Asscher and Princess diamonds are square-shaped diamonds, but they are vastly different in how the facet are cut and arranged.
Cut also refers to the shape of the diamond. The shape is often determined by how the molecules of the crystal are arranged. If it’s an octahedron, it will be cut as a round brilliant, and often two round brilliants can be cut from the same original crystal. Other crystal configurations, such as macer, will be cut as marquise or oval diamonds.
The modern round cut brilliant stone has 58 facets, or 57 if the tiny bottom facet, the culet, is omitted. The Princess cut is unique in that it’s a square diamond with pointed corners. Many diamonds, even square and emerald cut diamonds will have rounded or cut-off corners, because contrary to popular opinion, a diamond can chip or scratch if it knocks against something at the wrong angle. It’s a bad idea to try to scratch a mirror with any diamond!
An emerald shaped diamond is a rectangle cut with longer, flat facets. It’s a good cut for a diamond that’s exceptionally clear. If it’s not, then an emerald cut diamond can appear cloudy.
The Asscher diamond is similar to an emerald shape, except it’s square. It’s cutting resembles a spider web when viewed from above.
Other diamond shapes are self-explanatory. A pear- or tear-shaped diamond is exactly that. It’s an oval that’s wider at one end and curves to a point at the other end. An oval is a perfect oval. The marquise-shaped diamond can maximize the carat weight of a stone because it’s a longer and flatter cut, yet highly faceted. The marquise comes in a variety of length-to-width ratios.
