I’ve purchased an item online, now what?
Our jewellery is made to order and the magic happens in a small workshop. As a result online orders will take approximately 4 weeks to complete from the day of purchase. You’ll receive and email once your item has been shipped.
What if I want to make a ring that isn’t on your online store?
Reach out to us via email. We would love to hear what you have in mind to create. Anything is possible!
How long does it take to make a custom design?
From hand selecting your diamond, to creating your ring - the custom design process takes approximately 6 weeks.
What materials do you work with?
Quality is everything for us! We only use 9 & 18ct white, rose or yellow gold and platinum for our designs. Although we mostly work with diamonds, we work with any natural gemstone. All materials used by Kolmio are ethically and responsibly sourced and great care is taken with the custom manufacturing of each piece.
I don’t know what my ring size is?
You’re most welcome to make a quick appointment with me to get you size measured professionally. Alternatively, you can visit your local jeweller for peace of mind. Unfortunately, Kolmio cannot be held responsible for inaccurate sizes.
S (J, J-, K, K-)

Please select your size (S - XL) according to the guide and enter your exact ring size (British measurement) in the “Special Instructions” text box during checkout. If your ring size isn’t listed, you would like to change the design of the band or you need help with sizing, please email us for a quote and / or assistance.
What if I need my ring resized?
In the event that your ring size has changed, we’ll be more than happy to resize your ring to a perfect fit. Please keep in mind that some designs have limitations to sizing. Sizing cost vary due to metal prices and labour costs. Should you require a resize, please get in touch.
Can I exchange my order?
Our jewellery is specially made for you, unfortunately you cannot exchange or refund your order.
What if I don't live in Pretoria?
No problem! We have clients all over the world and would love to collaborate with you on your custom design. The custom process happens via email, over the phone or in person. When it comes to hand selecting your diamond, we send you high quality images and videos so that you can get a true visualization of your options.
What if I live overseas?
We've got you covered! For custom orders, get in touch to start the bespoke process. To order an item from our online store, send us an email and we'll send you an invoice with your order and international shipping rate. Payments can be made through PayPal or a wire transfer. Once your order is ready, we'll ship it to your door with DHL express. It takes approximately 5-20 working days to arrive, depending on where you are.
Can I have my outdated ring remade into a modern design?
Absolutely! We love remodeling old jewellery and would love to reset your diamonds. Your old metal is sent in for refining, in order for us to work with a pure alloy. With the refining process there are slight losses involved and we’ll have to add some new metal to be able to create a new piece. You therefore get discounted on your metal cost. If you have an old piece of jewellery that doesn’t get the love it deserves, get in touch to give your old piece a makeover!
Are your diamonds ethically sourced?
Yes! We work with a trusted network of suppliers who source diamonds ethically and sustainably.
