Choosing a diamond is more than selecting a stone, it’s selecting brilliance, rarity and lasting value.
At Matusik Jewellers in Mount Lawley, we guide clients through the complete diamond selection process, from understanding the 4Cs of diamonds, Cut, Colour, Clarity and Carat, to sourcing exceptional loose diamonds tailored to your ring design.
Whether you’re purchasing an engagement ring or creating a bespoke piece, this diamond buying guide will help you choose with confidence.
“The Most Important Factor”.
More than just the shape of the diamond, the cut determines how well a diamond reflects light.
Even a high-quality diamond can appear dull if poorly cut.
A well-cut diamond will display brilliance, fire and scintillation.
We carefully assess:
• Proportions
• Symmetry
• Polish
• Light performance
Cut is the hardest part of diamond selection to quantify. It can make the difference between brilliant and dazzling and dull and lifeless. Our years of expertise will help you choose the
brightest stone to sparkle forever.
“How White is the Diamond?”
Diamond colour is graded from D (colourless) to Z (noticeable tint).
The less colour present, the rarer and more valuable the diamond.
We guide clients through selecting the best balance between:
• Colour grade
• Setting style
• Metal choice
• Budget
For example, yellow gold settings can complement slightly warmer diamonds beautifully.
“Natural Inclusions”
Clarity refers to natural internal characteristics formed during the diamond’s creation.
Grades range from:
• Flawless (FL)
• Internally Flawless (IF)
• Very Very Slightly Included (VVS)
• Very Slightly Included (VS)
• Slightly Included (SI)
Most inclusions are microscopic and invisible to the naked eye.
We help you identify eye-clean diamonds that provide exceptional value without overpaying for invisible grades.
“Diamond Weight”
Carat refers to the diamond’s weight, not its visible size.
Two diamonds of equal carat can appear very different depending on cut proportions.
We assist clients in choosing:
• Ideal carat weight
• Best face-up appearance
• Proportions for maximum brilliance
