Center Sapphire
The stone at the heart of this piece is a 5.5 carat yellow sapphire, cushion cut and anchored by a four prong setting atop a cathedral shank. The sapphire represents faithfulness, purity, and reliability, all of which make is a fitting choice for an engagement ring. The client chose a yellow stone in this case, but you can easily substitute a different colored sapphire to make the design better suit your tastes.
Halo Setting
Surrounding the center stone is a halo of split prong set diamonds that both add their own sparkle to the piece and help to enrich the color of the sapphire. This type of halo setting also gives you a way to incorporate the more traditional diamonds into your engagement ring without making them the centerpiece.
Choosing Materials
While getting just the right look for your custom engagement ring is important, you also have to take into account the properties of the materials used. In this particular case, the client was concerned about the ring being resilient enough to stand up to the rigors of his fiancee’s active lifestyle.
Keeping that in mind, our designers helped him make the appropriate choices, like selecting platinum for the ring itself. This is the strongest of the metal options, and using it ensured that the large center stone would be kept more secure in place. Similarly, sapphires and diamonds are very hard stones, making them appropriate choices for a ring that has to look gorgeous while still holding up to the rigors of everyday wear.
No matter what type of ring you want to create or what your specific concerns might be, our designers will bring their extensive knowledge to the project to ensure we produce exactly the piece you’ve been dreaming of.
