My father passed away last month and left me a small amount of money. I would like to get a ring in his memory. We were both born in August so peridot would be a natural choice. I really like peridots that are more of an olive color and am wanting a 3-5 carat stone surround by diamonds in a halo style ring. My concern is that I want to wear it daily, not as a special occasion ring, and I know peridots are too soft for that. Are there any other alternatives? I am not familiar with gemstones except for peridot and diamonds.
