The Betty solitaire engagement ring is a refined expression of love — designed to mark life’s most heartfelt promises. With its graceful lines and timeless silhouette, this ring offers understated luxury and meaningful beauty for the one who holds your heart.
At the centre of the Betty ring lies a brilliant oval-shaped stone, secured by four elegant claws. The elongated shape of the oval diamond flatters the finger while maximising sparkle and light. Whether you choose a Natural Diamond, Lab-Grown Diamond, Coloured Gemstone, or supply your own special stone using our diamond ring builder, the Betty is crafted to honour your unique love story.
The band, made from lustrous 9k white gold, is designed with delicate accent stones to enhance the ring’s brilliance. You may opt for accent stones in Natural Diamonds, Lab-Grown Diamonds, Moissanite, or none at all — giving you the freedom to personalise your engagement ring to your exact style. The balance between sparkle and simplicity ensures the centre diamond remains the hero.
Each Ralph Jacobs piece is proudly handcrafted in South Africa, where our jewellers blend traditional techniques with modern precision. We are deeply committed to ethical sourcing, using only conflict-free diamonds and responsibly sourced materials. Built for comfort and strength, the Betty is designed for daily wear, offering both beauty and resilience.
At Ralph Jacobs Jewellers, we believe your engagement ring should be as enduring as your love. With a dedication to quality, honesty, and personalised service, we offer more than just a ring — we offer a legacy to treasure for generations to come.

"I don't know much about diamonds and rings so I can't comment on that besides to say everything was well packaged and came with the accompanying documentation. On service: up there as one of the greatest customer experiences I've had. I got helped by Sameeya who do an incredible job at managing my expectations and keeping me informed along the way. The phonecalls after each step of the process are invaluable and provide piece of mind during a nerve-wracking process. The information on the site is well and accurately documented and the short wait time when you call in is great. I've got zero complaints and found my provider for life for the products they sell. Thank you."
"My fiance loves her ring. Ralph Jacobs were professional and extremely helpful and answered all our questions timeously. We will definitely be looking here again when we are ready to buy wedding bands."
"Absolutely great service from Nick and Rikus I think it was? The ring is amazing and beautiful! The box it's presented in though, is not to my taste; a sort of heavy cement or maybe soapstone box with magnetic seals. It's novel and probably expensive, but I would have preferred something a bit more classic looking? Would purchase again! 😁"
"This is one outstanding company!!! If you are looking for moissanite jewelers, then Ralph Jacobs is definitely the company that you want to do business with. They are super professional and ensures that every customer is treated as their main priority and constant updates from the team makes you part of the entire process. Ralph Jacobs- kings of moissanite rings."
"We received our ring in August for our 5th Wedding Anniversary - I was blown away by the service that Rikus offered, his knowledge of the product and his advice. Thank you Ralph Jacobs for making my dreams come true."
"We purchased this ring in a rose gold - It is truly stunning! The engraving detail is beautiful. The service from Ralph Jacobs has been fantastic! They kept me updated throughout the process and have been very helpful with having my ring resized a bit smaller."
"They called me weekly with updates and news about my order. Very impressed with the service and quality of the ring!"
