Engagement Ring Styles We Craft
Every ring is designed from scratch — but these are the most popular starting points our clients bring to their first consultation.
Solitaire
A single diamond in a clean, minimal setting. The most timeless engagement ring style — designed to maximize the stone and let it speak for itself. Available in four-prong, six-prong, and bezel settings.
Halo
A center stone surrounded by a ring of smaller diamonds, creating the illusion of a larger diamond and adding brilliance. Single halo, double halo, and hidden halo variations available.
Three-Stone
Three diamonds representing your past, present, and future. The center stone is typically larger, flanked by two complementary side stones. A meaningful and striking choice.
Vintage & Art Deco
Intricate detailing inspired by antique designs — milgrain edges, filigree, and engraved shank patterns. We study period-correct techniques to create rings that feel authentically vintage.
Cathedral
Arched metal supports that elevate the center stone, creating a dramatic profile. The cathedral setting adds height and presence while keeping the diamond secure.
Pavé & Micro-Pavé
Tiny diamonds set into the band itself, adding sparkle from every angle. Pavé settings catch light beautifully and complement any center stone shape.
Diamond Engagement Rings in Toronto
Lab-grown diamonds are chemically and physically identical to mined diamonds — the only difference is where they formed. Both are real diamonds, with natural centre stones typically graded by GIA and lab-grown centre stones commonly graded by IGI.
At OROSERGIO, we offer both natural and lab-grown diamonds because we believe the right choice depends on your priorities, not ours. Lab-grown diamonds are usually priced substantially lower than comparable natural stones, which means you can go bigger on the stone, invest in a more intricate setting, or save the difference for your future together.
Natural diamonds carry the romance of a billion-year geological journey and generally hold their value better on the secondary market. During your consultation, Sergio will show you both options side by side in natural light — most clients are genuinely surprised at how identical they look.

Why Toronto Couples Choose OROSERGIO
The OROSERGIO Atelier
Our craftsmen bring decades of experience, blending old-world savoir-faire with contemporary design and modern techniques. Everything is made under one roof in downtown Toronto.
Timeless, Without the Wait

No Middleman
When everything is done in-house by a Master Goldsmith and CJA member, you receive exceptional quality through direct atelier pricing.
Choosing Your Metal
Gold is available in yellow, white, and rose — all three are the same metal alloyed differently for colour. The real choice is between platinum, 14K gold, and 18K gold.
Platinum
The most durable precious metal. Naturally white, hypoallergenic, and develops a distinguished patina over time. Heavier feel on the finger. Never needs re-plating. The premium choice for clients who want their ring to last generations without maintenance.
Premium — most durable14K Gold
The most popular choice for engagement rings. 58.5% pure gold, balanced with alloys for everyday durability. Available in yellow, white, and rose. Slightly more resistant to scratches than 18K. White gold is rhodium-plated for a bright finish (complimentary re-plating at OROSERGIO).
Most popular — best value18K Gold
75% pure gold with a richer, warmer tone than 14K. The higher gold content gives it a deeper colour that many clients prefer, especially in yellow gold. Slightly softer than 14K, making it a better canvas for intricate detailing. Available in yellow, white, and rose.
Richer colour — luxury feel19K White Gold
The richest white gold colour available — often called "super white." 19K white gold achieves a brighter, more naturally white tone than 14K or 18K white gold, reducing the need for rhodium plating. A premium option for clients who want the whitest possible gold without choosing platinum.
Super white — richest white gold19K Yellow Gold
Also known as Portuguese gold, 19K yellow gold has the deepest, warmest yellow tone of any gold alloy. With 79.2% pure gold content, it delivers an unmistakable richness that 14K and 18K cannot match. A favourite among clients of Portuguese heritage and anyone who appreciates the deepest gold colour.
