Canadian Diamonds, Certified From Mine to Ring.

H&Z is also a Canadian diamond specialist. Mined under strict Canadian environmental and labour standards, each stone is conflict-free, traceable, and laser-inscribed for identification — arriving with a certificate of origin that guarantees its authenticity.

Whether you're set on a lab-grown stone, a natural diamond, or one mined in Canada, the conversation starts the same way: sit down with our team, see the stone in person, and get a straight answer about what you're buying.

Custom Craftsmanship

Every piece is fitted by hand with extreme precision.

H&Z has been setting stones in Ancaster for decades — long enough to have designed rings for a client's daughter after designing hers. Every visit is a private, appointment-based consultation: no rotating sales floor, no quotas, just a straight answer about the stone in front of you.

That's the same discipline we bring to lab-grown diamonds: independently certified by IGI or GIA — the same laboratories that certify mined stones — chemically and optically identical, at 50–70% less than a comparable mined diamond. And because H&Z sources lab-grown diamonds wholesale-direct, pricing sits below typical retail markup — ask about it at your consultation.

Common Questions

Lab-Grown Diamonds, Answered

Yes. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds — the only difference is origin. Every stone we sell is independently certified by IGI or GIA, the same labs that certify mined diamonds.

Typically 50–70% less than a comparable mined diamond of the same size, cut, and clarity, because lab-grown stones skip the mining and global distribution markup.

Our showroom is at 1142 Wilson St W, Ancaster, ON — a short drive from Hamilton, Dundas, Stoney Creek, Waterdown, Flamborough, and Burlington. Book a free consultation and we'll have pieces pulled and ready when you arrive.

We're open Tuesday through Saturday, 9:30am–5:30pm. Booking a free consultation ahead of time means you get our full attention with no wait.
