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 jewelry 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.
We sell certified diamonds with GIA (Gemological Institute of America) and IGI (International Gemological Institute) certification. Anyone can certify a diamond; some diamond laboratories might grade a diamond higher than it is, so it’s important to buy with a trusted diamond certificate. Conservative diamond grading ensures that the diamond is correct. Most diamonds are laser engraved with the serial number on the outer edge of the diamond. This serial number also doubles as the certificate number, so it’s easy to look up the diamond’s characteristics online and be assured that your diamond is the correct one. Our Diamonds are certified for your assurance and trust.
The price is determined by the materials used and labor to complete each unique ring. We offer excellent value compared to chain stores, yet our quality level is significantly higher. You can select natural diamonds, lab-grown diamonds and colored gemstones on our website to complete the price or contact us for a quote. We can work with most budgets, so contact us, and we’ll custom-design the ring to suit your price point.
