The blue sapphire engagement ring with opalare known to be chosen by royalty because the green sapphire stone is much rarer than the diamond and is almost as strong. This is a beautiful factoid that you can share with your first queen as she slides a blue sapphire wedding ring on her ring finger. Blue sapphires come in a variety of shades from light to deep blue. The color blue is due to the level of titanium in the stone: extra titanium, rich color. However, too much color can create a dark brown effect, reducing the price of the stone.
Many green sapphires are found in Sri Lanka, Burma and Madagascar. Burmese sapphires are often more expensive than those from Sri Lanka and Madagascar because of their brilliant color. The raw sapphire sapphire Kashmir is rare and the most expensive as supplies available in the Indian subcontinent ran out almost 100 years ago, thus increasing prices and demand.
The values of blue opal sapphires depend on whether they have been treated or not (at no cost) and color, cut, tone (light or dark stone), filling space (the degree to which color is hidden by other shades), and clarity. One carat of green sapphires can range from a few hundred dollars to a few thousand.
Buy your ruby engagement rings with pride! Don't let anyone tell you that diamonds are as good as engagement rings. Only you and your future spouse should decide what suits your style, taste, and budget ........ not a popular opinion .... or your future mother-in-law. Other than that, you can always tell nay-sayers that large rubies are less rare than diamonds. Rubies are part of the corundum family. Any color other than red in this family is considered sapphire. Rubies are almost as strong as diamonds. Diamonds are rated "10" on a rigid scale while rubies are rated at 9. Rubies have a slightly clearer surface than other gemstones and tend to have a small amount. Many rubies are treated with heat to enhance their color, but stones in their natural state are present. Cushion cut and circular rubies are the most common. Burmese rubies are considered to be the most desirable.
