FAQ — Johannesburg
Do I need to travel to buy bespoke diamond jewellery?
No. The entire process is remote — WhatsApp, phone, or video call. We send HD stone videos, certificate scans, and design visuals. David delivers in person wherever possible, otherwise your piece arrives fully insured via tracked courier.
How does delivery to Johannesburg work?
David delivers in person wherever possible — straight to your door. If David is not able to deliver personally, your piece is sent fully insured via tracked courier to all JHB suburbs — Sandton, Fourways, Randburg, Midrand, Rosebank, Melrose Arch, and beyond. Signature required on receipt. Discreetly packaged.
How does Diagem compare to Sandton jewellers?
Sandton retail carries significant overhead — prime rent, display stock, large staff. Those costs are embedded in every price. Diagem has none of that, so you pay substantially less for the same GIA-certified stone in the same setting. Test it: request a quote from any Sandton jeweller for a 1ct G VS2 solitaire and compare.
What's the delivery timeline to JHB?
Most bespoke pieces are delivered within 1–2 weeks from stone confirmation. Complex multi-stone designs may take up to 4 weeks. We give you a clear timeline upfront. We give you a clear timeline upfront.
