Questions
Engagement ring questions
Quick answers before you message David.
Do I choose the diamond or the ring design first?
At Diagem, the centre diamond comes first. David helps you choose a natural GIA-certified or lab-grown IGI-certified diamond, then the ring design is developed around that diamond and the style you have in mind.
Can Diagem help if I do not know what style she wants?
Yes. You can send David inspiration photos, a ring she likes, a budget range, or a simple description of her style. Diagem helps translate that into a practical engagement-ring direction.
Do you make engagement rings for online checkout?
No. Diagem is a diamond dealer first, not an online jewellery checkout. Engagement rings are handled by enquiry and appointment so the diamond, budget and design can be checked properly.
Can I choose natural or lab-grown diamonds for an engagement ring?
Yes. Diagem can guide you through both GIA-certified natural diamonds and IGI-certified lab-grown diamonds, depending on your budget, timing and preference.
Where can I view engagement-ring diamonds?
Diamond viewings are arranged in Johannesburg. Cape Town appointments may be arranged with David by prior arrangement.
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are real diamonds with the same crystal structure as natural diamonds. Diagem explains the difference in origin, value and certificate type so you can choose the right centre stone for the ring.
What does the R10,000 excl. VAT / R11,500 incl. VAT starting price include?
A complete ring with a 1-carat lab-grown diamond in 9-carat gold is from R10,000 excl. VAT (R11,500 incl. VAT). The final price depends on the selected diamond, gold weight and design. Prices are indicative and subject to exchange-rate changes; confirm your quote with David.
How long will my ring take to make?
David confirms the manufacture timing for your ring before you commit.
Is a deposit required?
A 50% deposit is required before manufacture.
Can my ring be delivered outside Johannesburg?
Discuss insured delivery across South Africa with David. Confirm dispatch timing, delivery charges and payment arrangements with your final quote.
