How to Create a Custom Engagement Ring

Do you want an antique diamond in a unique but new custom setting? Or, perhaps you prefer a more modern look with a vintage ethical stone. Whatever your style, the Erstwhile team can help turn your dream custom engagement ring into reality.


Start by choosing your favorite Erstwhile setting and than let your imagination run wild. Customize your dream setting with your choice of metal and antique diamond cut, color and clarity. Play around with different diamond choices using our easy dropdown system to figure out your ideal budget. Once you get feel for what your budget should be, contact our team to begin the creation process. You will work with a dedicated antique diamond expert that will help you find the right stone based on your custom setting, budget and taste. You will receive videos, detailed communications, and GIA certificates of possible stone options. Nothing is final until we find the perfect dream diamond for your setting. Once the stone is selected a 50% non refundable deposit is required to move forward. You will receive detailed photos and videos of your ring before your remaining payment. Allow 4 to 6 weeks for the creation process.
