Royal Blue. Brilliant White. Absolutely Unforgettable.
Some color combinations are just meant to be — and royal blue sapphire with white diamonds is one of the most iconic pairings in fine jewelry history. This 14k gold ring centers a rich emerald-cut sapphire (approx. 7.7 mm × 5.5 mm, 1.50 ct.) in a four-prong setting, flanked by sparkling princess-cut diamonds (approx. 0.40 ct.) that frame the sapphire’s deep, velvety blue with brilliant contrast.
The emerald cut was chosen to showcase the sapphire’s color to its fullest — its long, open facets let the blue saturate and glow in a way that round cuts simply can’t match. The result is a ring that feels both regal and modern, equally at home as an engagement ring or a statement piece for any occasion.

About Sapphires
Sapphires have been worn by royalty for centuries — most famously on the finger of Princess Diana and now Kate Middleton. Their deep blue color comes from trace amounts of iron and titanium, and no two sapphires are exactly alike. Sapphires rate 9 on the Mohs hardness scale, second only to diamonds, making them one of the most durable gemstones available and an excellent choice for everyday wear.

For the most accurate fit, measure in the evening when fingers are slightly larger. Need a size not listed? Contact us — we offer custom sizing on select styles.
Care & Wear
Sapphires are one of the most durable gemstones available, making this ring ideal for everyday wear. Clean periodically with warm water, mild soap, and a soft brush.

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
- For special occasions: The vivid green and black gold combination is a showstopper at any event
- As a milestone gift: A truly unique anniversary, birthday, or celebration ring
Metal Options
- Black Gold — Dramatic and avant-garde. The ultimate contrast to the vivid green tsavorite.
- Yellow Gold — Warm and classic. Enhances the rich green of the tsavorite with timeless elegance.
- Rose Gold — Romantic and modern. The blush tone creates a stunning, unexpected pairing with vivid green.
Perfect for: Non-traditional engagement rings, statement jewelry collectors, milestone gifts, or anyone who appreciates rare gemstones and bold design.

14k Gold Oval Tanzanite & Diamond Ring
Bold, rare, and breathtakingly beautiful. This stunning ring features a generous oval tanzanite — one of the world's rarest gemstones, celebrated for its deep velvet-blue hue — set in a four-prong basket with an ample, polished 14k gold shank. Flanked by sparkling diamonds, it's a ring that commands attention and tells a story of extraordinary taste. A gem as rare as the person who wears it.
- Metal: 14k Gold (White, Yellow, or Rose Gold)
- Center Stone: Oval Tanzanite — Triple-A grade, 1.19 ct, deep velvet blue
- Center Stone Size: 8.0 mm × 6.0 mm
- Accent Stones: Diamonds (0.76 ct tw)
- Total Carat Weight: 1.95 cts tw
- Setting: Four-Prong Basket with Ample Shank
- Style: Engagement / Statement Ring
The Oval Advantage
The oval cut is one of the most flattering shapes in fine jewelry. Its elongated silhouette creates the illusion of a larger stone, makes fingers appear longer and more slender, and offers exceptional brilliance thanks to its modified brilliant faceting. An oval tanzanite of this size — 8.0 mm × 6.0 mm — delivers a commanding presence on the hand without sacrificing delicacy. It is a shape beloved by design connoisseurs and modern brides alike.
Choose Your Metal
Available in three 14k gold options, each creating a distinct aesthetic with the tanzanite's rich blue-violet hues:
- White Gold — Cool and luminous. The icy brilliance of white gold amplifies the deep blue saturation of the tanzanite, creating a striking, high-contrast look with modern elegance.
- Yellow Gold — Warm and editorial. A bold pairing that draws out the violet undertones of the stone, creating rich contrast reminiscent of vintage fine jewelry at its finest.
- Rose Gold — Romantic and refined. The blush warmth of rose gold softens the stone's intensity, resulting in a dreamy, feminine aesthetic that feels simultaneously contemporary and timeless.
About Tanzanite
Tanzanite is found in only one place on Earth — a small corridor near Mount Kilimanjaro in Tanzania — making it approximately 1,000 times rarer than diamonds. Its extraordinary trichroic nature means it shifts between blue, violet, and burgundy depending on the light source and viewing angle, ensuring the stone never looks the same twice. Triple-A (AAA) grade tanzanite represents the pinnacle of the category: the most intensely saturated, deeply vivid stones reserved for the finest jewelry.
As tanzanite's single-source deposits are finite and non-renewable, its scarcity — and value — continues to grow. This is not just a gemstone. It is a piece of the earth's rarest treasure.
Tanzanite is the modern December birthstone and a meaningful gift for 24th anniversaries, making this ring an inspired choice for milestone celebrations.
Jewelry Care
- Store in a soft-lined box or pouch, away from other pieces to prevent scratching.
- Clean gently with a soft brush, mild soap, and warm water. Pat dry with a lint-free cloth.
- Remove before swimming, exercising, or applying lotions and perfumes.
- Have your ring professionally inspected and cleaned once a year to maintain prong integrity and stone security.
