This certificate describes in detail the purity of the gold, the stone(s) used as well as their weight, clarity and color and finally the replacement value in the event of loss or theft. The certificate is written by one of our diamond experts with the St-Onge seal. Providing this certificate to your insurance company will give you peace of mind.
Natural Diamonds
Natural diamonds are diamonds that were created in nature millions of years ago. Created under intense heat and high pressure, natural diamonds are as unique as they are rare. This is precisely what gives them their value. Coming mainly from Canada, St-Onge natural diamonds are still the most prized today.
Lab Grown Diamonds
Lab grown diamonds (or synthetic diamonds) have the same chemical, physical and optical characteristics as natural diamonds. They are created in a laboratory using state-of-the-art technologies reproducing the same conditions under which natural diamonds formed, thus speeding up the manufacturing process. Lab grown diamonds is an alternative to natural diamonds.
