You can also initiate the custom design process through our website, and we can complete a project entirely online as well in case distance or scheduling pressures preclude you from coming in personally.
Three-stone Setting
At the top of this ring sits a 1.29 carat cushion shaped sapphire with a tantalizing blue color. It’s prong set in unplated 18k white gold, and it’s complemented beautifully by the round diamonds that sit on either side. These complete the three-stone setting, and they’re 0.60 carats combined. Their brilliant sparkle enhances the shine of the sapphire at the top, and it also contrasts nicely with the champagne color of the metal it’s set in. Three Stone Engagement Rings
Mokume Gane and Milgrain
The top of the band is covered in a beautiful mokume gane inlay down to about the three-quarter point. This is made of a combination of 14k white gold and sterling silver, and its gentle, organic lines are a wonderful addition to the design. This mokume section is also framed by a delicate milgrain beading that helps make clear its separation from the rest of the ring, and that also brings a hint of vintage flair to the ring.

Filigree
The prongs of the main setting rise up from an intricate filigree design on both ring fronts. The scrolls and waves in this design enhance the glamorous look of the ring, and they flow nicely with the pattern in the mokume gane inlay to give the piece a good balance.
