Getting Down To Basics with Diamonds

Knowing on Engagement Ring Options – Sapphires, Rubies and Emeralds Jewelry

Fine jewelry, aside from the top seller diamonds, makes use of other precious gemstones, such as sapphires, rubies and emeralds, which are set-up in various, creative designs as gemstone materials for engagement rings. Here is the outlined information of each gemstone.

Sapphires are Corundum minerals, which are basically composed of aluminum oxide compounds in crystalline form, and which comes in a variety of gemstone colors, such as blue, which is a common choice color, pink, yellow, green, purple. When sapphires come in a red form, it is called a ruby.

A jeweler’s standard guidelines, the 4 C’s – cut, clarity, color and carat, is the yardstick in assessing a gemstone’s value and quality, such that for sapphires, in which they are rarer than diamonds, their clarity of the stone, color and carat value will depend on the source location of where the sapphire stone was mined, with blue and pink as high valued gemstones, while their cut will depend on the jeweler’s creative design.

After diamonds, sapphires are among the hardest gemstones, with a Corundum composition structure that measures a scale of 9 on a Moh’s hardness scale, which tells that sapphires have stable durability and which can be used as a gemstone ring.
Getting To The Point – Rings

Sapphire gemstones have been historically associated with royalty and symbolize sincerity and faithfulness, such that King Solomon’s seal was believed to be made from sapphire, Prince William of England proposed to Kate Middleton with his mother’s iconic sapphire engagement ring, and 45th wedding anniversaries use sapphire as its symbolic ring celebration.

With the same Corundum composition, like that of sapphires, except that it comes in a red form, which is due to the presence of chromium, being an impurity in the stone, but considered a rarity, rubies are highly valuable gemstones.

The value of rubies is that they are extremely rare gemstones, in fact much rarer than diamonds, and that’s why they are classified as highly valued gemstones, especially those mined from Burma. They, too, are among the hardest gemstones attaining a scale of 9 in the Moh’s hardness scale, which are just like the sapphires.

Emeralds are related gemstones of aquamarine, helidor, and morganite, as all have the same mineral component, which is beryl. The grass green emerald color in emeralds is due to the presence of chromium, which is actually an impurity in the composition structure of the stone, but which makes the emeralds as very rare and highly valuable gemstones, just like rubies.

Because they are hard to find in gemstone mines, emeralds are rarer than diamonds and the range of their degree of value is dependent on the range of their green coloring, such that the intense grass green color is most desirable and, therefore, highly valuable compared to the pale green color.

Because they are reasonably durable based on the Moh’s scale, in which they have a scale of 8, emeralds are vulnerable to heat damage and extreme changes in temperature, which can cause them to break.
