Sigma is a direct-from-factory brand. With our own in-house designers and skilled jewellery craftsmen, we source high-quality and affordable gemstones from around the world.

Inspired by the aesthetics of leading brands, our designs combine innovation with classic style, creating pieces that are elegant, modern, distinctive, and effortlessly refined.

Due to hygiene, safety, and quality control reasons, we do not offer returns or refunds on jewellery items.

However, we may be able to accommodate exchanges on a case by case basis, provided the item is unworn, in its original condition, and returned within 1 month of purchase.

Please carefully review product details, sizing information, and images before purchasing. If you have any questions prior to ordering, please contact us and we will be happy to help.

At this time, we only ship domestically in Canada.

However, if you live outside of Canada and really love our product, contact us directly and we will try to work something out!

Most deliveries arrive within 3 to 7 business days after the order is shipped out.

Pickup is available in the Vancouver area.
