Order by 2 December for priority production. Every order placed by 2 December 2026 goes into production straight away, with priority. We aim to dispatch before our workshop closes on 21 December, but some designs take longer, and courier times and public holidays add to delivery, so we can’t promise delivery before Christmas. Your delivery period and date are shown before you order. Need your piece by a set date? Tell us before you order.

Cathedral Engagement Rings
A solitaire is a single centre stone on a band. It is the classic engagement ring: nothing competes with the diamond, it is easy to wear every day, and a wedding band sits neatly beside it.
Every Ralph Jacobs engagement ring is made to order in South Africa. Start with a setting in yellow, white or rose gold or platinum, choose its centre stone from our certified natural and laboratory-grown diamonds or a gemstone, and add your ring size. We make the ring for you after you order.
Natural and laboratory-grown diamonds are both diamonds, with the same sparkle and hardness. Laboratory-grown diamonds give you a larger stone for the same budget; natural diamonds are rare and formed deep in the earth. Where a diamond is certified, its grading report comes from an independent laboratory, such as IGI or GIA.
Not sure which setting suits you? See settings and diamonds side by side in our showroom in Secunda, or book a virtual appointment. Delivery is free in South Africa, and our complimentary 60-day ring resize labour benefit covers one eligible resize.
