Lab-Grown

Lab-grown diamond engagement rings in Richmond Hill

More couples in Richmond Hill now start their search with lab-grown diamonds. They are genuine diamonds — the same carbon crystal, hardness and fire as a mined stone — at a fraction of the price per carat.

Every lab-grown diamond we set is independently graded by IGI, and most of our clients choose top colour (D–F) and very slight inclusions (VVS–VS). Whether you live in Bayview Hill, Oak Ridges or anywhere else in Richmond Hill, we’ll show you certified stones side by side and quote each option in writing.

Natural

Natural diamond engagement rings for Richmond Hill couples

Natural diamonds carry something a lab can’t — billions of years of history and true rarity. They also hold their value far better over time, which matters if your ring will become an heirloom.

We source GIA-certified natural diamonds to your exact specification — shape, carat, colour and clarity — and present a curated shortlist at your private appointment. Natural stones are priced individually, so we’ll quote yours after we understand what you’re looking for.

Lab-grown vs natural: our honest guide
Custom

Custom engagement rings, designed with you in Richmond Hill

Custom doesn’t have to mean complicated. For Richmond Hill couples, it starts with a relaxed private consultation and ends with a ring designed around one person’s hand and story.

Here’s how it works:

  • Consult: meet us privately, in person or by video, with no cost or obligation.
  • Choose your diamond: compare certified lab-grown and natural stones side by side.
  • Design: we refine the setting, band, metal and details with you and quote everything in writing.
  • Craft: your ring is made in our own atelier and checked by hand before it reaches you.

Want a head start? Our online ring builder lets you choose your diamond, setting and metal for an instant estimate before you even book.

How custom rings work
Styles

Engagement ring styles Richmond Hill couples love

These are the settings we’re asked for most — each one made to order in your choice of metal:

  • Solitaire — one diamond on a clean band; timeless and easy to pair.
  • Hidden halo — a secret ring of diamonds under the centre stone.
  • Halo — a frame of small diamonds that makes the centre stone look larger.
  • Three stone — past, present and future, with two side stones.
  • Toi et moi — two stones side by side, often in different shapes.
  • Bezel & east-west — sleek, modern and secure for active hands.

Popular diamond shapes include round, oval, emerald, radiant, pear, cushion and marquise, plus rarer cuts like Portuguese, old mine and Dutch marquise.

Pricing

How much does an engagement ring cost in Richmond Hill?

The honest answer: it depends most on whether you choose lab-grown or natural, and then on carat, colour, clarity and setting. As a guide, a 1-carat lab-grown round solitaire in 14K gold starts around $1,800 before tax with us, and a 2-carat lab-grown oval with a pavé band and hidden halo is around $3,800.

Natural diamonds are priced individually. Whatever your budget, we’ll show you where to spend and where to save — and every quote is in writing. Book your appointment online and save 10% on purchases of $5,000 or more.
