Once you’ve located the center stone for your diamond wedding ring, you can then shift your attention to the engagement ring. Metal type is an important component. Whether you use yellow gold, white gold, platinum or some alternative metal for your engagement ring, each will have an impact on the look of the center diamond, the ring’s structural integrity and how it ages over time. Using the NEJEX engagement ring database to find options is quick and convenient. All of the engagement rings are either owned by member wholesalers or retailers in Boston or New England, or are in CAD form, and easily and quickly casted in the metal of your choice.
