Made here, not imported
Each piece is cast, set, and polished to order at our Cape Town bench over up to 21 days, in silver, 9ct or 18ct gold, or platinum, with every metal's exact price shown side by side on the product page.

Consults wherever you are
Virtual consultations bring the showroom to you, anywhere in the country. Stones, metals, sizing, budgets: all of it over a video call, no Cape Town flight required.
The honest case for lab-grown in SA
South Africa knows diamonds better than almost anywhere on earth, so South African buyers deserve the straight version: a lab-grown diamond is chemically, physically, and optically identical to a mined diamond. Same carbon, same crystal structure, same Mohs 10 hardness, same fire, graded on the same 4Cs by the same independent labs. The full chemistry is in are lab-grown diamonds real?
The practical difference is price. A mined diamond of equivalent size and grade typically retails for 3 to 5 times the lab-grown price, and we publish the live rand numbers in lab-grown vs mined prices. Same sparkle on the hand, several rand brackets less on the invoice.
Learn before you spend
Our Ring School guides cover everything a careful buyer wants to know: metals, certificates, sizing, the made-to-order process, and how to insure the finished piece in South Africa. Free, honest, and written to be useful even if you never buy from us. (You might, though. Big yes energy is contagious.)
