St-Onge Canadian Diamonds

Natural Canadian diamonds have a story to tell. These diamonds of impeccable quality are ethically extracted from our Canadian soil. Buying a Canadian diamond also encourages local businesses and industry.

LEARN MORE ABOUT CANADIAN DIAMONDS

Lab Grown Diamonds

An alternative to natural diamonds is Lab Grown Diamonds. Lab grown diamonds are grown in a controlled environment under hihg temperature and high pressure. Just like natural diamonds, they are cut to obtain the utmost brilliance and fire. The difference is mainly reflected in their very affordable prices.

Diamond Certifications

GIA and CanadaMark certified natural diamonds and IGI certified Lab grown diamonds are used at St-Onge Jeweller. The independent GIA and IGI reports provide a complete description of the diamond while the Canadamark card confirms its origin. A certificate of evaluation for insurance purposes from our laboratory is also offered with any purchase at St-Onge.
