Description
This classic engagement ring features a radiant cut blue sapphire prong set in platinum, with channel set diamond accents. The design was developed in collaboration with a client who communicated with our team primarily online while he was stationed overseas. Although he wasn’t able to come into our Bellevue, WA showroom personally until the piece was complete, the skills of our designers and the high-tech tools we have at our disposal ensured that the ring he created for his fiancée was exactly what he wanted in every way.

Sapphire Center
The 1.89 carat blue sapphire at the center of this ring is radiant cut, which gives it a rectangular shape with truncated corners. It’s framed beautifully by the four low-profile platinum prongs holding it in place, as their shape and the angle of their placement complement its contours nicely. Sapphire Engagement Rings
While diamonds are often thought of first as the traditional gemstones to use in engagement rings, sapphires are frequently used in this way as well. They are nearly as hard as diamonds, making them a good choice for a piece of jewelry that will be worn every day, and they come in a wide variety of colors, which opens up many more design possibilities.
Diamond Accents
Even though the main stone in this ring isn’t a diamond, our client liked the idea of working them into the design in some way, although he wasn’t set on the placement or the type of cut he wanted when he first came to us. After exploring several options, he eventually settled on the arrangement seen here, with seven round channel set diamonds, slightly tapering in size, running down each shank shoulder.
The combination of round stones with a channel setting really enhances the classical feel of the piece, and the diamonds themselves contrast beautifully with the rich blue of the sapphire. The way that they taper slightly also goes along with the gentle widening of the band as it nears the center setting, and this gives the ring a wonderful balance and grace.
