The “Diadem” diamond-accented solitaire ring is named for the crown-like appearance of the gallery, which is delicately accented with diamonds.  Each ring is precisely matched to the gemstone that will be mounted in it by adjusting the CAD design and creating a custom model for casting.  The ring has a mix of 1.0 and 1.5 mm diamonds of F-G color and VS-SI1 clarity; the minimum total diamond weight is 0.29 carats. A custom matching wedding band can be special-ordered by contacting us.

The “Diadem” ring can be created in 14k or 18k yellow or white gold, 14k rose 0r 20k pink gold as well as platinum.  Simply select the precious metal you’d like and specify your size; this ring can be made in US sizes 4-8, including fractional sizes.  The typical turn-around time for creation of the ring is 3-4 weeks from the date of your order.  All rings are delivered in a custom wooden gift box and come with a lifetime warranty against any manufacturing defect.
