  • Antique Diamond Three-Stone Engagement Ring, Circa 1930

    Antique Diamond Three-Stone Engagement Ring, Circa 1930

    This 1930s ring offers a unique take on the classic three-stone engagement ring. Its 18ct white gold mount is generously studded with delicate round-cut diamonds that elegantly trace the ring’s distinctive shape. Amidst the flurry of smaller diamonds are three principal diamonds, their weight amounting to a generous 1.02ct. The jeweller has employed an intricate open work setting allowing each of the three central stones to breathe. The design also enables the eye to glide fluidly over the ring and take in all of the different elements. With a total combined weight of 1.26ct, this ring emanates a lot of brilliance, and the jeweller has maximised that by pairing the pristine stones with metals that complement their hue. The setting of this ring is distinctive and unique. It is easily paired with a wedding band for a complete and timeless look and is extremely flattering on the hand.

Frequently Asked Questions

Find out about resizing, certification and shipping at The Antique Ring Boutique

Can a ring be re-sized?

Yes, most of our rings can be re-sized; unless stated in the item description. Simply add your required size in the notes section at checkout, and our team will take care of the rest!

What is my ring size?

If you are unsure of your ring size after choosing the perfect ring, please consult the sizing guide here or contact us to get a more accurate gauge of your ring size.

How long does re-sizing take?

Please allow an additional 5 to 10 working days to the delivery time. If you require your order for a particular date, please get in touch as soon as possible, and we will do our best to accommodate.

Can I purchase a ring and later return it to be re-sized?

Yes, we do. For example, if you have recently purchased a vintage engagement ring online, but it is not quite the right size for your partner, we can resize it. There is no additional charge for this but the buyer is responsible for the return postage and insurance upon return.

Does the ring come with a certificate?

While most of our rings are accompanied by gemological certificates, it is possible to provide a certificate to rings which don’t already have a certificate. There is an additional charge for this. All of the rings are checked and examined by a professional gemologist before they reach the website.
