How do I choose my birthstones?
Choose two stones: usually your own birth month and that of someone you love. You can also pick the colours you like best. See our Birthstone Guide for the meaning of each month.
How do I find my ring size?
Our ring is available in sizes EU 49 to 65 (US 5 to 11). Our Ring Size Guide explains how to measure at home with a piece of string or a ring you already own. If you are between two sizes, choose the larger one.
What is the jewellery made of?
Each piece is made from 316L stainless steel, available in gold (18k gold PVD plating) or silver tone. The necklace chain measures 45 cm, with a 5 cm extender.
Is it suitable for sensitive skin? Can I wear it in water?
Yes. 316L stainless steel is hypoallergenic and our jewellery is water-resistant, so everyday contact with water is fine. To keep the shine for longer, we suggest taking it off before swimming, the sauna or the gym.
How do I care for my jewellery?
Wipe it gently with a soft, dry cloth. Avoid perfume, lotions and household chemicals, and store each piece on its own to prevent scratches.
How long will my order take?
Without personalisation: 7–10 working days. With personalised birthstones: 14–16 working days, as each piece is made for you before it is shipped. Full details on our Shipping & Delivery page.
Is delivery really free?
Yes. Delivery is free on every order to the United Kingdom, with no minimum spend.
How can I track my order?
As soon as your order ships, we email you a tracking link. You can also log in to your account or visit our Track Your Order page.
Can I change or cancel a personalised order?
Please contact us as soon as possible at Support@kalmeris.com with your order number. If production has not started yet, we will do our best to update or cancel it. Once a personalised piece is being made, it can no longer be changed or cancelled.
Can I return my order?
Items without personalisation can be returned within 30 days of delivery, for any reason (return postage is paid by you). Personalised items (with birthstones you chose) are made especially for you, so they cannot be returned for a change of mind. If they are faulty or damaged, we will always find a solution: a replacement or a refund. See Returns & Refunds.
What does the 12-month guarantee cover?
Every piece is automatically guaranteed for 12 months against manufacturing defects. No registration or certificate is needed: your order confirmation is enough. If something is not right, email Support@kalmeris.com with your order number and a photo, and we will repair, replace or refund it. This is in addition to your statutory rights.
How does the "Buy 1, get the 2nd free" offer work?
Add two items to your basket and the second one is free. You can mix the ring and the necklace, and choose different stones or colours for each.
Is payment secure?
Yes. Payments are processed through Shopify's encrypted checkout. We never see or store your full card details. The available payment methods are shown at checkout.
How can I contact you?
Email us at Support@kalmeris.com or use our contact form. We are available Monday to Friday, 9:00–18:00 (UK time) and reply within 24–48 working hours.
