Diamond coloration mechanics and sapphires

The formation of precious stones with metals such as gold at the vicinity of stream beds was considered to be a property of those, who were rich and powerful, since historical times. The term diamond was used for indestructible, or the one which cannot be tamed. These were some of the hardest and rarest stones such as the Hope diamond, which was found in India, a 45 carat stone, having rare distribution of Borons that cause steely blue color.

Diamond was favored by western buyers earlier, as it represented commitment, and the rituals to use it to propose before marriage got popular. The promotional made by the De Beers in 1947 said ‘A Diamond is forever’ and ‘rubies were girl’s best friend’ etc.  Such advertisements were made, whilst, the brands introduced these stones as collectibles and linked its marketing strategies to the high net worth individuals.

Stones and religion

Before 20th century such stones were bought due to the aristocratic or occult nature. These were also used in traditional cures. Some of the rare medical conditions involved the use of gems in medicines of ayurveda. These were believed to be empowered with energies, which could protect the royals from evils or negative energies.

Coloration is significant, although, earlier it was believed to be a negative feature due to impurities. These days’ buyers look for the ones with great colors – where the basic mineral in the stones is the same corundum but are formed into rubies and sapphires colors, due to the presence of certain other minerals.

Unique gems - Sapphires

Sapphires can be a corundum crystal of red, while, some believe the blue one is the real one. The blue is formed due to the bouncing activities of electrons between doses of iron and titanium atoms.  The level of such elements can be measured exactly but some random formations can make it look blue – that is responsible for the charge transfer.

Emerald is soft in comparison to white diamond and sapphires, and is mostly formed from the infusion of beryllium – which is toxic. Emeralds are formed by the compression of rocks and toxic metals, which can be clean green as found in the mountains of Colombia or muddy with high refractive power of beryl. The most popular combination of stones is made into diamonds or sapphires embedded in platinum.
