Sapphires, Rubies and Emeralds as Engagement Rings
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. Provided are the background information of sapphires, rubies and emeralds.
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. For sapphire stones, which are in a red form, they are no longer called sapphires, but rubies.
Sapphires are rarer than diamonds and its value depends on the 4C’s – cut, clarity, color and carat, such that the cut will depend on the jeweler’s creative design, while the 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.
The Beginner’s Guide to Sales
Sapphires are among the hardest gemstones, after diamonds, due to the fact that its Corundum composition is on a Moh’s hardness scale of 9, meaning that sapphires have stable durability, which can be used as a gemstone ring.
Getting To The Point – Rings
Sapphire stones are highly valued not just for its rarity, but also because of its historical association to royalty and its symbol of 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.
Like that of sapphires, rubies have the same Corundum composition, but with the exception 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, making rubies as valuable gemstones.
Rubies are classified as highly valued gemstones, especially those mined from Burma, because they are extremely rare to find, that’s why they are rarer than diamonds. Attaining a scale of 9 in the Moh’s hardness scale, rubies, just like sapphires, are among the hardest gemstones.
Formed from a mineral called beryl, which is also the same mineral component in such gemstones as aquamarine, helidor, and morganite, are emerald gemstones. 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.
Depending on the color range of their green coloring, emeralds vary in their degree of value, , such that the intense grass green color is most desirable and, therefore, highly valuable compared to the pale green color, and, at the same time, their rarity, due to their uncommon presence in gem mines, makes them rarer than diamonds.
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.
