Built around fusion, contrast, and connection.
This ring features a 1.00ct sapphire center, framed by heart-set natural rubies on each side. With their softer, naturally pink hue, the rubies bring warmth and tenderness to the sapphire’s deep blue tone—creating a design that feels like two energies meeting in perfect balance.
The blue sapphire symbolizes loyalty, trust, and enduring devotion, while the pink-toned rubies represent passion, affection, and emotional strength. Together, they reflect a love that remains steady while still feeling alive, expressive, and deeply personal.
Leaf-inspired detailing along the band gives the piece an organic, almost magical quality—as though it were grown from love, memory, and protection. Crafted in solid gold, the design balances softness with strength: romantic, emotional, and quietly powerful.
Made for those who believe love is never just one thing.
It is layered. It changes. It grows. And when it is real, two different energies become something stronger together.

Find Your Ring Size
Measure Your Finger
- Use a flexible measuring tape or length of string.
- Wrap it around the finger you'll wear your ring on. If you're creating a ring stack, consider where on your finger the ring will sit. If using string, mark the point on the string where the ends meet with a pen.
- Lay the string on a flat surface and use a ruler to measure the length (in inches or millimeters) up to the mark. Compare your measurement to the size chart to determine your ring size. If you are between sizes, opt for the larger size.
Measure an Existing Ring
- Choose a ring that already fits your finger well.
- Measure the interior diameter of the ring in millimeters (mm).
- Use the measurement chart to match the size of your ring to the closest size in mm. The interior of the ring should align with the outer edge of the circle.
Luther's At Your Service
There's no question too small or request too large for Luther's Diamonds client advisors. From choosing an engagement ring or gift to providing in-store or virtual appointments, we're always at your service.
Watch how your ring is made.
Every ring that leaves our studio passes through these stages — cast, ground, set, and hand-polished. Not by a factory line. By the same small team, in the same small workshop, for over a decade.
Grinding After Casting
Once the gold is cast in its rough form, every surface is carefully ground down by hand to reveal the ring's true silhouette.
Setting the Stones
Each stone is placed by hand and secured into its setting — one at a time, under magnification, with full attention to symmetry and seat.
Hand Polished
We still hand-polish every ring. No tumblers, no shortcuts. The mirror finish you see is the result of progressively finer abrasives, worked by hand until the metal sings.
Finished Ring
Before it ships, every ring is inspected one last time by Jack — checking the stone seat, the polish, the comfort of the band — and only then does it leave the workshop.

Stories from the people who said yes.
Every ring we make passes through our family workshop before it reaches a doorstep. Below are the moments that followed — in their own words, with their own photos.
I bought this ring to celebrate a new chapter in my life, and honestly… best decision I've made in a while. The craftsmanship is stunning. The diamond has serious presence without being loud (hidden halo), and the setting is elegant, timeless, and very 'put-together.' I've gotten so many compliments. Thank you Jack, thank you for the amazing family team to make this happen.
Creating the perfect engagement ring was super easy with Luther's Diamonds. From start to finish, they ensured every detail was exactly what I envisioned. The 1:1 CAD model was such a reassuring step in the process, giving me the confidence that this ring was going to be everything I dreamed of and more. I'm so grateful for their expertise, and my fiancée couldn't be happier with the final result!
The proposal was perfect, and the ring truly exceeded everything I imagined. Jack & the team created something incredibly special, and seeing my fiancée’s reaction made me realize even more how much care and craftsmanship went into it. It never felt like just buying a ring — it genuinely felt personal from beginning to end, and that’s something we’ll always remember.
The ring looks amazing!!! I had it shipped to my uncle's place to keep it a secret, and the team communicated everything perfectly. They really understood my situation and helped make sure this ring stayed part of the secret project. PURE perfection!
The details on this ring… I cannot put into words!!! More I look at it, more stunning it is :)
Definitely coming back for a wedding band, as this ring is stackable!!!
The close-up details on this ring are unreal. Thank you, Jack, for working with my fiancé (husband now) and arranging delivery as well.
She loved it. Highly recommended :)
Gosh I love this ring!
