Buying a Diamond Ring? Start with Expert Advice
Buying a diamond ring is a meaningful investment — whether for an engagement, a milestone gift, or a custom design. To help you make the most informed decision, here are our expert tips from Alexander Jewellers, proudly serving Sydney since 1981.
1. Pick a Trusted Jeweller
Choose a reputable, certified jeweller with a strong track record and positive reviews. A trustworthy jeweller will guide you through the 4Cs and offer certification with full transparency. At Alexander Jewellers, our GIA-certified diamonds are backed by decades of expertise and customer trust.
2. Know the Right Ring Size
It’s surprising how often this step is overlooked! Have the wearer’s finger properly measured to avoid resizing later. If the ring is a surprise, we can assist with discreet sample rings and sizing guidance.
3. Set a Realistic Budget
Before browsing, decide what you’re comfortable spending. A clear budget helps narrow your options and ensures you get the best quality within your means — whether it’s a natural or lab-grown diamond.
4. Understand the 4Cs: Carat, Cut, Colour, Clarity
These four key features affect a diamond’s look and value:
- Carat – Weight of the diamond
- Cut – Affects sparkle and brilliance
- Colour – Rated D (colourless) to Z (light yellow)
- Clarity – Based on natural imperfections
We help you balance these elements to suit your budget and desired brilliance.
5. Think About the Setting and Style
- Prongs: Choose 4 or 6 prongs for security and style.
- Band Metal: Consider white gold, platinum, or yellow gold — based on style, durability, and skin sensitivity.
6. Check the Diamond Under Different Lighting
Natural, store, and daylight lighting can affect how a diamond appears. Always examine the diamond under various lighting conditions before purchasing.
7. Ask for Certification and Hallmarks
Only buy diamonds with an independent certificate (e.g., GIA or IGI). Also, check for Australian hallmarks on the ring band to verify authenticity and gold purity.
8. Consider Lab-Grown Diamonds
For those seeking an ethical and affordable alternative, lab-created diamonds offer the same brilliance, structure, and durability — at a lower price. They’re growing in popularity among modern couples.
