This could be an inherited diamond ring that is too gaudy to wear, a diamond that looks extremely bland, or something carrying an outdated design, etc.       In some cases, it is best to design a diamond engagement ring using diamonds you already have at hand. That way, you get to imbue a sentimental touch to the ring, and also contribute to environmental conservation, since requires mining a diamond is far from good for the planet. Plus, you would save a lot on your overall diamond ring expense. When it comes to building a diamond engagement ring using old gemstones, it is better to work with a well-known diamond ring designer, since they would be able to easily pin down the best possible designs. The diamond that you have in hand may not be suitable for every kind of band. In case you cannot afford to hire a designer for this, you can simply go to a jewelry store and choose a suitable ready-made mounting for your gemstone, with the jeweler’s help. He or she could set your gemstone in the mounting right in front of you so that you do not have to worry about your diamond being switched with a replica.
