About Blue Sapphire
Sapphire has been the gemstone of royalty for centuries — prized for its rich, velvety blue color, exceptional hardness (9 on the Mohs scale, second only to diamond), and timeless elegance. The deep blue of a fine sapphire is unlike any other gemstone: saturated, luminous, and alive with depth. It is the stone of wisdom, loyalty, and enduring love — making it one of the most meaningful choices for an engagement ring or milestone gift.
The Trillion Cut Side Stones
Trillion-cut diamonds are triangular brilliant-cut stones known for their exceptional sparkle and dramatic, modern silhouette. Flanking the sapphire on either side, they amplify the center stone’s color while adding a bold, architectural quality to the overall design. The result is a ring that feels both classic and completely contemporary.

- As a right-hand ring: A bold statement piece for the woman who loves color and drama
- For special occasions: The deep blue and sparkling diamonds make this ring a showstopper at any event

About Tsavorite Garnet
Tsavorite is one of the rarest and most coveted gemstones in the world — a vivid green garnet discovered in the Tsavo region of East Africa, prized for its extraordinary brilliance, rich color saturation, and exceptional clarity. Unlike emeralds, tsavorite requires no treatments or enhancements to achieve its stunning color, making it a truly natural treasure. Triple-A quality tsavorite, like the stone in this ring, represents the finest grade available — deep, pure green with exceptional transparency and life.
About Black Gold
Black gold is 14k gold that has been treated with a specialized rhodium or ruthenium plating process to achieve its dramatic, matte-to-glossy dark finish. The result is a metal that feels entirely contemporary — bold, architectural, and unlike anything in traditional fine jewelry. Against the vivid green of the tsavorite and the brilliance of the diamond accents, black gold creates a contrast that is nothing short of extraordinary.
How to Wear It
- As an engagement ring: A bold, non-traditional choice for the woman who writes her own rules
- As a statement ring: Wear it solo on the right hand for maximum impact

The Depth of the Ocean, Set in Gold
There are rings that are beautiful, and then there are rings that make people stop and ask. This is the second kind. A stunning emerald-cut Triple-A tanzanite (approx. 8.6 mm × 6.5 mm, 2.0 ct.) sits at the center of a uniquely crafted mounting adorned with brilliant white diamonds (approx. 0.50 ct.) — the deep blue-violet of the tanzanite playing off the sparkle of the diamonds in a way that feels almost alive.
The emerald cut was chosen deliberately here. Its long, open facets showcase the tanzanite’s extraordinary color saturation and trichroic shift — the way it moves between blue, violet, and burgundy depending on the light and angle. No other cut does this better. The result is a ring that looks different every time you glance at it.
Tanzanite is found in only one place on earth — a single square mile at the foot of Mount Kilimanjaro in Tanzania. Once those mines are exhausted, there will be no more. Owning a piece like this is owning a piece of geological history.

The Color of Twilight, Set in Gold
There are gemstones, and then there is tanzanite. Found only in a single square mile at the foot of Mount Kilimanjaro, tanzanite is one of the rarest gems on earth — a thousand times rarer than diamond. This ring puts that rarity front and center with a breathtaking 2.5 ct. octagon-cut Triple-A tanzanite (approx. 9.0 mm × 7.0 mm) in its richest purplish-blue hue, a color so deep and velvety it seems to hold the twilight sky within it.
Flanked by two princess-cut diamonds (approx. 0.46 ct. combined) in a prong setting, the contrast between the vivid violet-blue tanzanite and the brilliant white diamonds is nothing short of spectacular. Set in polished 14k gold, this is a ring of extraordinary presence — a collector’s piece for someone who refuses to settle for ordinary.
Whether chosen as an engagement ring, an anniversary gift, or a personal statement, this ring will be remembered. It’s the kind of piece that gets passed down.
