Three-stone Setting
The main setting in this ring is made up of a 2.74 carat radiant cut blue sapphire and two princess cut diamonds. Taken together, the diamonds total 0.37 carats, and they’re tension set significantly below the larger center stone. Their squared shape complements the sapphire’s radiant cut nicely, and the brilliant white of the diamonds provides a perfect counterpoint to the rich blue above.
While diamonds are the stones most commonly thought of as the centerpiece of an engagement ring, sapphires can ably fill this role as well. They’re nearly as hard as diamonds, making them able to handle the rigors of daily wear with ease, and they come in a wide selection of colors. This makes them a great option if you want to add some color to your ring, and using diamonds elsewhere in the design lets you still maintain that connection to the traditional. Three Stone Engagement Rings
Diamond Accents
The split shank of this piece is lined with round bright cut set diamonds from the mid-point on the band all the way up to the main setting. The split begins just where the diamonds do, half-way up the side, and the two pieces slowly diverge, eventually widening just enough to run along either side of the princess cut diamonds in the main setting.
Hand-cut Filigree
A beautiful filigree heart fills the space between the base of the prongs that rise up to form the setting holding the center sapphire. On the outside of the prongs, the fronts of the shank shoulders feature a cut-out filigree pattern specially requested by our client.
Due to the nature of our production process, this type of custom metalwork is hand-crafted by our expert artisans, allowing us to customize it to a great degree. That makes including something of personal significance to you and your partner that much easier, and even if you’re not sure what type of pattern or design you’d like, we can show you plenty of examples to help you find the one that creates just the right look.
