Is a CVD diamond a real diamond?

Yes. A CVD (Chemical Vapor Deposition) diamond is a real diamond in every scientific and gemological sense. It is chemically, physically, and optically identical to a mined diamond. The only difference is origin: CVD diamonds grow in a controlled laboratory environment rather than underground.

Are lab grown diamonds as good as real diamonds?

Yes. Lab-grown diamonds are real diamonds, graded by the same international standards as mined stones. Ronora uses only CVD lab-grown diamonds graded D-E-F colorless with VVS-VS clarity (VVS1 or VVS2 wherever available, VS1 only when neither is). They have the same hardness, brilliance, and durability as mined diamonds.

Does my ring come with IGI certification?

Every lab grown diamond of 1 carat or more in your ring comes with its own IGI report, in any metal. Smaller diamonds meet the same VVS-VS clarity and D-E-F colorless standards but do not get an individual IGI report. Every gold ring also comes with an SGL jewelry certificate and every platinum ring with an ITPL jewelry certificate; 925 sterling silver rings do not come with a jewelry certificate. All diamonds are independently selected to these specifications.

Can you shower with a lab-grown diamond ring?

It is safe but not recommended as a daily habit. Soap, shampoo, and conditioner leave a film on the diamond that dulls its sparkle over time. If you shower with your ring regularly, clean it weekly with warm water and mild dish soap to maintain full brilliance.

Can lab grown diamonds be worn every day?

Yes. Diamond scores 10 on the Mohs hardness scale. It is the hardest natural substance and is designed for everyday wear. Lab-grown diamonds are physically identical to mined diamonds and will not scratch or lose brilliance with daily use.

Can I get my ring resized after purchase?

Yes. Website orders include one free resize within 6 months of purchase, where the design allows; you only cover the delivery to our workshop. Contact us via WhatsApp or our contact page to arrange resizing for your ring.

How long does production and shipping take?

All Ronora rings are made to order. We make your piece in 10 days and deliver it in 10 to 15 days: free standard shipping takes about 15 days and express shipping up to 10 days, tracked and insured.

Do you ship to the USA, UK, and Australia?

Yes. Ronora Diamond ships to the USA, UK, Australia, Canada, and internationally. All orders are sent via tracked and insured courier. Production is based in Surat, India, the world's diamond crafting capital.

Product Details

This radiant three stone lab grown diamond ring is for the woman who wants sharp, architectural lines instead of another rounded silhouette.

A radiant cut center diamond is flanked by two tapered trapezoid step cut diamonds in a clean four prong setting. Real lab grown diamonds, not cubic zirconia, in D-E-F colorless and VVS-VS clarity, grown in a lab and set by hand in Surat.

The trapezoid side stones taper toward the shank, echoing the radiant center corners and drawing the eye straight to the middle of the ring. It is a modern take on a three stone ring, precise in its geometry and bright from every angle.
