Yet if you can be flexible with that, you can choose rings featuring birthstones on it.       The tradition of choosing a birthstone diamond ring can also be followed as per the zodiac sign. As far as the date goes, note that engagements tend to be at its peak from November to February since several holidays fall during those months. In fact, a diamond ring commercial about the right time may ring true when a holiday season is around the corner. That can be an indicator of the right time to purchase a large carat ring for her. Even though you will get multiple opportunities to make the proposal anytime during the year, such as when there is a family gathering to celebrate a member’s milestone, proposing marriage during the holidays always works out. Yet if you were going for Valentine’s Week, you can gift a promise ring on the promised day, followed by a proposal diamond ring on the proposal day to make it even more close to heart.
