Thinking about selling diamond jewellery in Edmonton - Canada? Before accepting an offer, it helps to understand what makes your diamond valuable. Diamonds aren't valued the way gold is. Instead of weight and purity, a diamond's worth comes down to four specific characteristics that jewellers call the 4Cs. Understanding them can help you feel confident about what your diamond jewellery is really worth.

Meet the 4Cs of Diamond

The internationally recognised 4Cs—Colour, Clarity, Cut and Carat Weight — are key factors used to describe diamond quality.

1. Colour
Diamond colour is graded on a D-to-Z scale, with D representing colourless to Z representing noticeably tinted. Generally, diamonds closer to colourless are rarer and can command higher values.

2. Clarity
Clarity describes how many natural inclusions or blemishes are visible within the stone, graded on a scale from flawless to included. Clarity refers to a diamond's internal inclusions and external blemishes. GIA's grading system ranges from Flawless to Included, with characteristics assessed under magnification.

3. Cut
Don't confuse cut with shape. Cut refers to how well a diamond has been shaped and faceted. Cut relates to how effectively a diamond interacts with light, influencing its brilliance, fire and sparkle. For standard round brilliant diamonds, GIA's cut scale ranges from Excellent to Poor.

4. Carat Weight
Carat is simply the diamond's weight. Carat measures a diamond's weight—not its size. One carat equals 0.2 grams. Two diamonds with the same carat weight can have very different values depending on their colour, clarity and cut.

What Does This Mean When Selling?

The 4Cs are an important starting point, but the value of your diamond jewellery can depend on several other factors, including the quality and authenticity of the stone, documentation, setting, jewellery condition and current market demand.

Why a GIA-Certified Evaluation Matters?

GIA, the Gemological Institute of America, is the internationally recognized standard for diamond grading. Having your diamond assessed by someone with real GIA training means you're getting an accurate, unbiased evaluation rather than a rough guess. Our in-house GIA Diamonds Graduate brings over 20 years of hands-on experience to every appraisal.

Common Myths About Selling Diamonds

"My diamond is insured for a certain amount, so that's what I'll get for it." Insurance value reflects replacement cost at retail, which is very different from resale value — this is one of the most common misunderstandings we help clear up.
"My diamond is old, so it's probably not worth much." Older and antique diamonds can actually carry collectible value beyond their basic 4Cs, especially with distinctive vintage cuts.
