Circles with opinions.
Add versatility to your X2 Boulder Stud Earrings with this optional piece. While the stud colour remains the same, you can mix and match the second layer with a different colour, allowing you to create various colour combinations.
PLEASE NOTE: This is an optional addition only if you already own a pair of the X2 Boulder Stud Earrings.
They are for the woman who wants a small piece to say something. Easy, light, and quietly expressive, they make everyday dressing feel more considered without asking for extra effort.
Why collectors keep coming back
- Lightweight and comfortable: Made from hypoallergenic stainless steel, these sculptural earrings sit comfortably on the ear without pulling, pinching or feeling heavy through the day.
- Single earring replacement: If one earring is lost, Iris can usually make a replacement rather than asking you to buy a full new pair.
- Handcrafted in Melbourne: Made by hand in the inSync studio, one pair at a time.
- Lifetime care: If anything ever goes wrong, Iris will repair or replace them.
- Award-winning design: inSync design has been selected for museum stores including the V&A, SFMoMA and the National Museum of Australia.
X2 Boulder Stud Earrings - - 100% hypoallergenic stainless steel, 22ct matt gold plate, black powder coat
X2 Boulder Stud Earrings - - 34 x 22mm (1.33 x 0.86 inch)
Try them with Burst Brooch - 22ct Matt Gold Plate, X2 Meander Necklace - Additional 2nd Layer, and Orbit Ring - 22ct Matt Gold Plate when you want the whole look to feel intentional without becoming overdone.
X2 pieces are designed to be customised. You can wear the base piece as it is, then add another layer or finish when you want more movement, contrast or colour.
The extra layer is removable, so the same piece can feel quieter one day and bolder the next.
If you are building your first X2 combination, start with the finish you will wear most often, then add contrast.
Can I change the look later?
Yes. X2 pieces are designed so you can add another layer or finish when you want more contrast, movement or colour.
Will they feel too bold?
Wear the base piece first, then add contrast when you want more presence. X2 lets you build confidence gradually.
Are they comfortable?
Yes. They are made to feel light and secure, even when the shape has presence.
What if I lose one earring?
Iris can usually make a single replacement rather than asking you to buy a full new pair.
Your piece ships from our Melbourne studio. Free Australian shipping is available on orders over $150.
Shipping, taxes and any discount codes are confirmed at checkout. If your piece is not quite right, you can return it under our easy returns policy.
If you do not love your chosen piece once it arrives, send it back for a full refund.
Every inSync piece is also covered by our lifetime guarantee. If something breaks through normal wear, we will repair it for you.
The right earrings can make a simple outfit feel considered. These bring artful shape and colour without asking you to overthink the rest.
How to wear it
Wear them with a simple dress, linen shirt or clean black top. They work best when the face, neckline and colour can speak together.
The compliment effect
One of the loveliest things about wearable art is the way it invites a comment. Someone notices the piece, then asks the story behind it.
Made with care
- Handmade in Melbourne with considered materials, a careful finish and every element thoughtfully resolved.
- Packed in eco-friendly, beautifully crafted packaging with a light scent for a considered unboxing experience. Prefer fragrance-free? Leave a note at checkout and we will sort it.
- Checked by hand before it leaves the studio, so it arrives ready to be worn, loved and kept.
