If a diamond is a girl's best friend, that means maintenance is a must.

With your best friend, you call her, text her when you know she is feeling low, and, if she lives far away, make sure that you see her at least once a year, just to keep the relationship fresh and strong. 
The same is true for diamond ring care. You would not expect your friendship to last forever without upkeep. You should not expect your ring to stay beautiful and strong on its own either. 

With just a few easy steps, you can keep your bling blinging for years to come. 

Without condition, ensure that once a year--at least--you take your diamond ring in to a jeweler. You may think that you can clean your ring on your own, but only the precision and skill of a seasoned jeweler will be able to give it that deep clean that will give it that deep shine. 

They go beyond soaking the ring in solution and cleaning the "seen." They have the capacity to check the prongs and mountings, get out any deep seeded dirt, and tighten them if they need tightened. You don't want that diamond falling off. 

The key to diamond care is proactivity. You may have checked over your ring yourself--nothing seems loose. However, you may have missed a place where the gold has run thin and is near to snapping. A jeweler would be able to catch accidents before they happen. 

Not just any jeweler will do, either. Ask your friends and family. They will either know the name of someone you absolutely should not trust or the name of someone they have used and value. 

Step two in proactive diamond care is to keep it separate from any other piece of jewelry. You may not think this relates to you. After all, you keep your wedding ring on your finger. But what about that lovely piece of jewelry passed down to you from your great great grandmother? That pendant, ring, bracelet, etc. 
Diamonds are the hardest stone available. That means they scratch, and they especially scratch one another. Scratches can be repaired by a skilled jeweler by buffing out the gash, but this is a travesty that could have been prevented with ease, if your piece of jewelry had been kept separate from others. 
The extra space is worth seeking out if it will prevent you from having to seek out some extra cash to cover the scratch buff. 

Finally, remember to remove your diamonds when you do hard work, especially if it is a ring. You put your hands to hard work in hard conditions. Your diamond cannot recover as easily as you can. So, when you find yourself using bleach, shocking the pool, painting the house, moving heavy furniture, take off your ring and put it in a safe place. You can come back and put it on later. You do not want to struggle against the chips or scratches, discoloration, or mount destruction that comes from pretending your ring is indestructible.
