Cultured Stones Are Grand Rivals To Real Diamonds

Rhinestone (high-leaded glass) is known as diamante and is made of rock crystal

, acrylic or glass. These are called Strass after Georg Friedrich Strass, a jewelry maker who has coated a lower part of rock glass for it to look in just the same way as stone. And indeed, the glistering strass effect resembles adamant gloss, as a result sometimes strass-diamond is percieved as natural gem. Just the customers who do not have the ghost of a notion of real diamond can be screwed, the other - without a chance. Crystal doesn't have qualities typical for real gem, such as firmness, refractory property and life span. Ground is both these gemstones have different structure and kind. Surely, diamante's price is by far lower thereby everyone can afford purchasing it, but in any case it won't be as a real stone.

Another favorite diamond simulant on jewelery market is CZ (Cubic Zirconia). It as isomteric as a natural diamond. This feature makes it to look like a 100% natural diamond gemstone. However, Cubic Zirconia is synthetic material that's why in order to form crystals and make them stay solid at ordinary temperatures , a stabilizer is always essential. Generally calcium or yttrium can be such stabilizers, but the amount of them is estimated by producers independently. The thing is stabilizing oxides remain in the manufactured product. It actually makes the stone weight much more than natural stone. Besides the CZ's dispersion is much higher in comparance with diamond. That's why, it is easy to shaft an amateur and to convince him CZ is a real diamond gemstone, anyway, cubic zirkonia will without any doubt break the high pressure testing - just hit it with smth. very heavy, solid as diamond gemstone.

The rest of the replacements will not pass both destructive test or thermal one, or even in both of them. It can seem that not a thing left to turn the diamond low-priced for real people. Yet, in 1954 a serious rival to mined stone was created - simulated diamond. It differs from all other stone substitutions by characteristics, conditions of synthesis, composition and physical structure. Artificial gem is synthetized in laboratory under HPHT conditions, that copy real circumstances that are required for cration of a diamond. Man-made diamond gemstone consists of 100% the same material as real stone - carbon. Cultured diamonds do have the same characteristics as natural gemstones: chemical, optical and physical. These of the longevity, solidity and glistering effect as natural stones. In addition, they cost less and simpler to purchase. It's possible to both order them in Net or at any jewelry shop. For most particular clients lab grown gemstones are available in several fancy colours: blue, green, pink or yellow that are highly pricey and occasional when found in real nature. They are also might be purchased in loose stones or as diamond jewelry. As you see, for the time being "real" diamonds are affordable.
