Platinum 3-Stone Engagement Ring | 3.05 ct Asscher Diamond & Sapphires
Three stones. One center. Two sapphires. A design that has endured for a reason.
This three-stone ring pairs a 3.05-carat asscher-cut diamond — VVS2 clarity, excellent cut — with two step-cut sapphires in a seamless platinum setting. The geometry is deliberate: the clean lines of the asscher cut echo the rectangular profile of the sapphires, creating a composition that is architectural, bold, and deeply elegant.
Available to commission in any finger size, with your choice of diamond origin — lab-grown or natural mined.
Lab-Grown or Natural Mined: Why We Offer Both
We don’t have a preference — and we won’t push you toward one or the other. What we do have is a deep understanding of both, and an honest perspective on what each offers:
- Lab-grown diamonds are physically, chemically, and optically identical to mined diamonds. Graded to the same standards, with the same brilliance and durability — and they allow us to prioritize exceptional color and clarity at a fraction of the cost of a comparable natural stone. That savings goes directly into the quality of the stone and the craftsmanship of the setting.
- Natural mined diamonds carry a geological story billions of years in the making. For clients who value rarity, provenance, and the romance of an earth-formed stone, there is nothing quite like it. We source natural diamonds with the same rigor — prioritizing cut quality, ethical sourcing, and stones with genuine character.
Both options are available for this design. The setting, the craftsmanship, and the standard of quality remain the same — only the origin of the stone differs.

This white gold diamond tennis bracelet is absolutely beautiful
This white gold diamond tennis bracelet is absolutely beautiful. The flexible, oval design fits my wrist perfectly and feels incredibly comfortable to wear all day., in fact I never take it off. The clasp is easy to use, lies completely flush with the bracelet, and never catches on clothing looking seamless and elegant. It’s both practical and stunning, and quickly became one of my favorite everyday pieces.

Beautiful Tennis Necklace
The quality of this Tennis necklace is outstanding! I chose yellow gold for a little bit more casual look and it pairs well with a lot of different necklaces I own or it’s great on its own. Amy was a pleasure to work with and I highly recommend the Perfect Setting.
