While it is common among women to don diamond jewelry, men are also seen wearing diamond promise rings these days.     A black and white diamond promise ring can be the perfect symbol of exclusivity, fidelity, and commitment, and as the perceived gender roles are evolving constantly, men also feel comfortable wearing promise diamond rings. In fact, promise rings for men can be found in a myriad of styles in the gems and jewelry market. So choosing a diamond ring that perfectly matches the style and persona of your man is a lot easier today. It is seen that most men go for the simple designs and style options when choosing a promise ring, rather than opting for an extravagant ring featuring a huge stone and sophisticated metalwork. This is because low-key jewelry makes men feel more contented and composed. Yet again, choosing bold and masculine designs in sterling silver, tungsten or titanium are also a fad in this sector.
