It was an absolute pleasure working with Craig designing my special ring. Definitely 10 stars!

It has taken me 6 months to write this review but better late than never. In fact that statement sums up my experience with Craig Marks. He took a little longer to deliver than originally claimed but he delivered in the most magnificent fashion.

Frequently Asked Question
Why buy from Craig Marks Diamonds instead of a traditional jewellery store?
We design and craft custom engagement rings directly with each client — no expensive showroom markup, no generic stock. Since 2008 we’ve sourced certified diamonds and built rings around your style and budget, not the other way round. You’ll understand exactly what you’re paying for (cut, colour, clarity, carat) before you commit. Most clients come to us through referral for that transparency and personal service.
Do you make custom engagement rings?
Yes — custom design is our specialty. We start with a consultation on diamond, style and budget, then produce CAD images so you see and approve the exact ring before it’s made. We also craft matching wedding bands and can redesign inherited jewellery into something new.
Should I choose a natural or lab-grown diamond?
Both are real diamonds — the only difference is origin. Natural diamonds formed underground over millions of years and are valued for rarity; lab-grown diamonds are chemically and optically identical but cost significantly less, so you can get a larger or higher-quality stone for the same budget. We stock both and help you choose based on what matters most to you.
Can I buy an engagement ring online safely?
Yes, if you’re buying from an established jeweller. Every diamond we sell is independently certified, and we guide you through diamond selection, CAD approval and manufacture — with WhatsApp or phone support at every stage. Buying online also opens up a far wider range of diamonds and designs than most physical stores can hold in stock.
How much should I spend on an engagement ring?
There’s no fixed rule — the “2–3 months’ salary” guideline is just marketing. Set a budget you’re comfortable with, and we’ll maximise value within it: prioritising cut quality over hard-to-see specs, adjusting diamond shape, or considering lab-grown to get more size for less.
How long does it take to make a custom engagement ring?
Around 3–4 weeks from design approval. This covers consultation and diamond selection, CAD design and sign-off, then handcrafting, setting, polishing and quality inspection. Working to a proposal date? Contact us early — but we’ll always try to accommodate tighter timelines.
