Frequently Asked Questions (FAQ)

1. Choose Your Ring Style

Browse our collection in-store or online, or bring in your inspiration—anything from Pinterest, Instagram, or a design you’ve always loved. We can custom-make any ring style to match your vision.

2. Select Your Preferred Metal

Pick the metal that suits your style and skin tone. Popular options include:

  • Yellow Gold
  • Rose Gold
  • White Gold
  • Platinum

3. Pick Your Gemstones

We offer a wide range of ethically sourced, certified gemstones, including:

  • Lab-Grown Diamonds – sustainable, affordable, and stunning.
  • Natural Diamonds – a classic choice with investment value.
  • Coloured Gemstones – from blue sapphires to red rubies, emeralds, and more.

4. Find Your Ring Size

You can visit one of our shops to have your finger sized, or estimate it—we can resize it later if needed.

5. Get a Custom CAD Design

Once you’ve chosen the style, metal, and gemstone, we’ll create a realistic CAD (Computer-Aided Design) model for your approval. You’ll see exactly what the finished ring will look like before production.

6. Approve and Pay Deposit

Once you’re in love with the design, we take a 50% deposit to begin production. The final balance is due upon completion—typically within 1 to 2 weeks.

7. Expert Craftsmanship

Your ring is handcrafted in our state-of-the-art workshop. Our skilled goldsmiths meticulously hand-set and finish each piece with precision and care.

8. Quality Control & Presentation

Every ring passes a strict quality control check to meet our high standards. It is then placed in a premium presentation box with all documentation included.

9. Delivery or Collection

You can collect your ring in-store, or we’ll deliver it to your door via insured courier—free of charge once the final payment is made.

We design and produce to the highest standards possible. We do this by using Computer Aided Design (CAD) for clients to check the style in actual proportions. We then 3D print a resin copy to invest in Gold or Platinum. This ensures the smallest detail is transferred from the digital CAD model to the actual ring. Our skilled jewellery bench then polish the metal and set the diamonds or gemstones to perfection. The quality of manufacture is the best possible. The diamond or gemstone you select is the deciding factor. Our rings have a Lifetime Manufacturing Guarantee, and we have won multiple awards. The quality is exceptional.

At Polished Diamonds, we proudly offer a lifetime manufacturing guarantee on all the fine jewellery we create. This guarantee reflects our commitment to exceptional craftsmanship and ensures that the quality and integrity of your ring or jewellery item is protected for the original purchaser’s lifetime.
