Payment Info

We accept it all to make your buying experience that much sweeter! All payment methods are secure and reliable and you can rest assured that your personal details are kept safe and sound.

Delivery & Returns

We have a 7-day returns policy, which means you have 7 days after receiving your item to request a return. To be eligible for a return, your item must be in the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase. To start a return, you can contact us at sales@vanocboutique.co.za. If your return is accepted, we will send you a return shipping label, as well as instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted. You can always contact us for any return question at sales@vanocboutique.co.za Damages and issues Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right. All gems and jewellery leaving Vanoc Boutique will be certified and passed by The Gem Lab. Unfortunately, we cannot accept returns on sale items or gift cards. Exchanges The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item. Refunds We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, you’ll be automatically refunded on your original payment method. Please remember it can take some time for your bank or credit card company to process and post the refund too.

Our Story

Jeremy discovered that people wanting to sell their gems and jewellery didn't have a platform to do so. They could try auction but could realistically only get about 1/4 of the retail value which was the same as selling back to anyone in the gem and jewellery industry. The highest price one can expect from pre-owned gems and jewellery is about half the retail value. GemDiam was born to help those wanting to sell their gems/jewellery to get a fair price which is around half the retail value. GemDiam enables the seller and the buyer to get a fair price. The security of buying from GemDiam is that all the items have been checked and passed by The Gem Lab, one of South Africa's leading gem testing labs based in Cape Town.
