London Blue Topaz
Our visuals
Each piece of jewelry is captured and retouched by the Gemmyo team to provide a faithful and authentic representation.
Our visuals are designed to let you admire each piece from every angle, with enlarged images to reveal every detail. When you see them in-store, you will find that our jewelry is finer and more refined than the images suggest. The visuals worn also help you envision and understand the proportions better.
Regarding the color of the stones, Gemmyo provides visuals that reflect reality. Each stone is unique, with its own reflections and nuances. This uniqueness enhances their beauty and is what makes our craft so intriguing... and makes your jewelry so personal.
Feel free to come and discover our stones and jewelry by scheduling an appointment at our boutique. We will be delighted to welcome you. We can also provide more photos or arrange a personalized video call.
Gemmyorama Octogonal Pendant White gold, London Blue Topaz

The Gemmyorama Octogonal pendant in 18K white gold and London Blue Topaz showcases a stunning 6x4 mm octagonal center stone. Its East-West setting extends into a double border: first polished, then enhanced with a millegrain pattern on the outside—a traditional jewelry setting technique, repurposed here as a decorative ornament. The millegrain thus frames the center stone while allowing it to remain the focal point of the design. Designed to rest delicately against the skin, the pendant features a crescent-shaped bail, also adorned with a millegrain motif.
A word from our designer
"With the octagonal center stone in East-West, I sought to challenge conventions and create an unexpected balance. It becomes a contemporary good-luck charm, a talisman that one makes their own as an expression of self."

All the jewels in the European Union (including DOM-TOM) and Switzerland are covered by the 30-day return guarantee, provided that:

To keep it in perfect condition, we recommend storing it in its pouch or box when you're not wearing it or while travelling.
Try to store each piece separately to avoid friction and reduce the risk of scratches.
We actually have three box sizes.
First, a case adapted to our ring models and most of our earrings, its dimensions are: 6 cm x 6 cm x 4.5 cm (L x W x H)
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.
