Premium Diamonds Carefully Selected

Beautiful brilliance begins with proportion, transparency and careful craftsmanship. We review grading reports and examine the diamonds themselves, giving every selection a clear basis in quality.

RAGAZZA Premium Grade

Every RAGAZZA Premium Grade diamond comes with a GIA grading report. Our colourless selection requires D colour, VVS2 clarity or higher, and Excellent polish and symmetry, across round and qualifying fancy shapes.

A Closer Look with DAII™

Premium round brilliant diamonds must also score at least 7.00 on DAII™. Independently developed by RAGAZZA, this quality index assesses 16 factors to help compare proportions and quality differences beyond the 4Cs.

Diamond Inspection and Setting Quality

We examine brightness, fire, colour tone and transparency, alongside the balance between diamond and setting. Once set, we check the prongs, stone security, polish and overall finish.

FAQs about Engagement Rings

Are lab-grown diamonds suitable for engagement rings?

Yes. They suit those who value diamond brilliance, design and flexibility in their budget. Lab-grown diamonds are real diamonds; consider your partner’s preference for a lab-grown or natural origin, and compare the quality of individual stones. Learn why lab-grown diamonds are real diamonds.

How much should I budget for a complete ring?

The total depends on the centre diamond’s weight and quality, the setting metal, accent diamonds and design. Start by checking loose diamond prices, then explore ring settings. When comparing starting prices, confirm whether the selected configuration includes a centre diamond.

What are the requirements for RAGAZZA premium grade lab grown diamonds?

Premium Grade diamonds are certified by the GIA. Colorless diamonds require D color, VVS2 or higher clarity, and Excellent polish and symmetry. Round brilliant cut diamonds must also meet the DAII™ standard of 7.00 points or higher and be examined in person. Other shapes are selected based on their respective cut characteristics.

Can I choose a diamond and setting online?

Yes. Add your preferred loose diamond and a compatible ring setting to the same cart. Select the setting option without a centre diamond, then choose the metal and ring size. Order both together, and RAGAZZA will set the diamond into your finished ring.

How can I prepare if I do not know the ring size?

Refer to our ring sizing information, or visit a showroom for guidance and a fitting. If you are planning a surprise proposal, our advisers can discuss suitable ways to estimate the size.

How far ahead should I order?

A made-to-order diamond ring generally takes around 21–28 days, with diamond availability and delivery arrangements also affecting timing. Allow time before your proposal and confirm the delivery date when ordering. See our shipping information.
