Once you approve the CAD, we share diamond images and video. Then we make the jewelry and keep you updated during production. Finally, you receive photos and video of the finished piece before shipping. Ask us about engraving and the details you would like to personalize.

Pairing and jewelry care

Browse our wedding bands to explore a matching look. Before selecting a band, ask us to check how it fits beside this setting. A side-profile view helps you see the gallery and the space around the ring.

Clean your diamond jewelry gently with mild soap, water and a soft brush. Rinse carefully and dry with a microfiber cloth. Store it separately in a soft pouch or jewelry box. Also, avoid harsh chemicals, extreme temperatures and impact during physical activities. Check the setting regularly and contact us if a stone feels loose.
