Thésée Duo Ring Rose gold, Sapphire

-
The ring’s “square wire” design is sleek and flat, symbolizing two souls connected no matter the distance.
Two round gemstones soften the architectural lines, creating a striking contrast.
A discreet diamond is set into the base of the band, reinforcing its structure and enhancing durability.

The Thésée Duo ring is crafted from a sharply defined band, technically known as a “square wire”, creating a bold, architectural silhouette. Inside this graphic rectangle, two precision-cut stones appear to float weightlessly against the skin. To achieve this effect, Gemmyo has developed a unique setting: each stone is secured on three sides, leaving one edge entirely open. Tiny notches, nearly invisible to the naked eye, are carved inside the metal to hold the stones in place while maximizing light. A high-shine mirror polish enhances the brilliance of the ring, while its flat contours emphasize the clean, graphic lines. Its open design reveals the skin beneath, lending the piece an airy, modern feel, ideal for pairing with other Thésée creations such as the Thésée Love Brossée 3 mm wedding band or the Thésée Laque 3,5 mm wedding band.
A word from our designer
"The Thésée Duo ring has it all: geometric lines, a presence on the finger, and two stones that remain discreet but add a precious touch. As with all rings that feature tiny stones, I recommend choosing two diamonds, two rubies, two emeralds or two sapphires - it'll come off better!"

Our sapphire qualities
We carefully select our sapphires for their deep blue colour, the most sought-after shade. It's this shade that you will find in all our sapphire jewelry.
However to bring an even stronger symbolism to your jewelry, we also offer you the chance to choose a particular shade of sapphire for your jewelry. You can therefore personalise your creation with a shade of sapphire that will please you the most, from the lightest blue to the strongest shades.
We offer two colors of AAA-quality sapphires: a lighter shade (Ceylon sapphire) and a darker one (Thailand sapphire).
The exceptional sapphire features a particularly deep "Royal Blue" hue. Not too light, nor too dark, its color is extremely rare!
Find out moreOur AAA-quality rubies display a vivid red hue, with subtle, even tones for a harmonious brilliance.
An exceptional ruby stands out with its deep, intense red and rich reflections. Its vibrant glow and remarkable radiance make it truly unique.
Find out moreOur AAA-quality emeralds reveal a bright, luminous green with a natural balance—lively yet soft, capturing the essence of fine gemstones.
An exceptional emerald is defined by its intense, crystalline green—almost electric. A rare brilliance that enhances its depth and radiance.

We also have a second larger case for our wedding bands, pendants and bracelets the dimensions are: 8 cm x 6 cm x 4.5 cm (L x W x H)
We have a last case designed for bracelets of ring type, the dimensions are: 9 cm x 9 cm x 4 cm (L x W x H)
It is also possible to receive a piece of jewelry in a small cotton suede bag, in very rare cases, if for technical reasons a piece of jewelry would not be sufficiently supported in our classic box.
If you have any questions about the size of our cases, please do not hesitate to contact us directly.
