Whether you’re interested in seeing this ring with a different type or shape of center gemstone, or you think you’d like a colored metal to contrast with all of the sparkling diamonds on the band, our team will show you examples and mock-ups of your unique design until you’re completely satisfied that we’ve truly captured your vision. You can begin the custom design process by visiting our Bellevue, WA showroom in person, or you can reach out online to share your thoughts and learn more about what we can do for you.
Blue Sapphire Center
The centerpiece of this ring is a 1.58 carat oval blue sapphire. Its deep, rich color contrasts wonderfully with the brilliant white of the platinum it’s set in, and the four prongs holding it in place are perfectly spaced to frame it beautifully.
Sapphires are an excellent choice if you prefer something other than a diamond center for your engagement ring. They come in many different colors, so you can simply choose your favorite, or you can select one with a deeper personal meaning. Sapphires are also nearly as hard as diamonds, making them quite able to stand up to the rigors of everyday wear. Sapphire Engagement Rings
Diamond Halo and Accents
Surrounding the center sapphire is a halo of bright cut set diamonds, and these continue around onto the sides of the center setting as well. The halo adds its own sparkle, of course, but it also helps to intensify the shine of the center stone by reflecting more light up onto it from below.
Four rows of bright cut set diamonds extend down the shank shoulders to the mid-point on the band. Two of these are on the top, while the other two cover each of the ring fronts. They tie in nicely with the diamonds in the halo to unify the two sections of the ring, and the dazzling sparkle they produce gives the ring decidedly glamorous flair.
