Engagement rings with blue diamonds are very exceptional because they are too expensive. Something very close to a blue diamond may be viewed at the Smithsonian, which has the Hope Diamond, one of the most renowned blue diamonds in the world.
Here is some more information about blue diamonds for engagement rings:
A blue diamond acquires its color due to presence of tiny traces of boron or large volume of hydrogen in it. The blue color may range from just a slight hint of blue to deeper royal blue.
As you can perhaps guess, deeper blues are more expensive and desirable. Those with multicolor are not so expensive, as those are considered to have more than one impurity.
It was in the 80’s that people started getting more interested in colored diamonds and the interest peaked in the 90’s. It was the media and the celebrities using colored diamonds that added to their popularity.
Here, let’s consider the cost of a blue diamond ring. The price of a solid pink or blue diamond engagement ring could be anywhere from 10 to 50 times the cost of a same sized white diamond ring.
Don’t be surprised if a blue diamond ring is priced for even a million! Usually, regular diamonds don’t appreciate in value; rather their price comes down from the moment you buy, but you can expect the price of natural colored diamonds to go up over the years.
Think of the options you have. Because of their price, natural colored diamonds are not within the reach of most, yet you can manage to procure a colored diamond! Diamonds on being treated with the process of irradiation and severe heat can be made to acquire beautiful colors of varying shades.
Synthetic stones can also be produced in lab with the same impurities added that are there in natural diamonds. The process is rather complex, but you can have colored diamonds at affordable prices. However, don’t expect the price to go up over the years.
Another option is to pair off white diamonds with colored gemstones instead of just colored diamonds. Yet, if you must have a natural blue diamond engagement ring and the budget is limited, it will be worth considering colored diamonds as side-stones.
