FREQUENTLY ASKED QUESTIONS

Do you sell both lab-grown and natural diamonds?

Yes, we offer a wide range of certified natural and lab-grown diamonds to suit your preference and budget. We’ll help you understand the differences so you can make an informed decision.

What is the difference between natural and lab-grown diamonds?

Natural diamonds are formed over billions of years deep within the Earth’s crust under extreme pressure and heat. Lab-grown diamonds are created in a controlled environment using advanced technology that replicates the natural diamond-growing process. Both types are chemically, physically, and optically identical. The main differences lie in their origin and price.

Can I design my own engagement ring?

Absolutely! Designing custom rings is our specialty. You’ll work one-on-one with our design consultants to create a piece that’s truly unique, from choosing the perfect diamond to finalising the finer details.

Do you have ready-made rings and jewellery in stock?

Yes, we have a curated collection of ready-to-wear engagement rings, wedding bands, and fine jewellery at our Cape Town showroom.

Do I need to book an appointment?

Walk-ins are welcome, but we recommend booking an appointment to ensure you receive dedicated time and personalised service, especially for custom designs.

Do you ship across South Africa and internationally?

Yes, we offer secure, insured shipping both nationwide and internationally. We’ll make sure your jewellery arrives safely, no matter where you are.

Do you offer resizing or repairs?

Yes, we offer resizing, cleaning, polishing, and jewellery repairs. Your first resizing is free, up to 3 sizes smaller or bigger, to make sure your ring fits perfectly. Bring it in and we’ll assess what’s needed.

How long does it take to make a custom ring?

Our custom engagement rings typically take 7-10 working days, depending on the design and availability of your chosen stone.

What payment options do you offer?

We accept EFT, debit and credit cards, and also offer Payflex on orders under R20,000 ZAR. We do not accept American Express cards.

Do your diamonds come with certificates?

Yes. All our loose diamonds, both natural and lab-grown, are certified and laser inscribed by leading grading laboratories such as GIA and IGI. The certification number is engraved on each diamond for your peace of mind.
