The challenge is that a plain band won’t rest perfectly with just any engagement ring. The solution? Get a custom made tracer band (shown). With interest in vintage & antique designs, it isn’t as likely to find your dream engagement ring & wedding band in the same step.
Shown: this wedding band was designed to match the customer’s ruby engagement ring.
Keep in mind there isn’t rules for how the set should match. Once you’ve found a matching band for the bride’s engagement ring, the groom’s design follows. They should have a similar appearance, but keep in mind that the widths of the bands will be different. Matching the metals is another consideration to make, but again, rules can be broken in this decision.
