Engagement Ring 4 Carat Radiant Cut Lab Diamond Channel Band

We meticulously curate each diamond to ensure that you get only the best - without any tint and featuring excellent polish and symmetry.

We offer the option for you to purchase from our curated selection of diamonds and vendors, or you can choose your own diamond from our diamond portal. Our diamond portal features up-to-date inventory of all the highest quality available diamonds. With Magdalene Pivoine, you don’t have to compromise on quality or size to create the diamond ring of your dreams.

Our center diamonds are DEF and VS1 clarity and come with a grading report from GIA, IGI, or GCAL. Each center diamond is  laser-inscribed with a serial number that matches the grading report.

Our side diamonds are of VS clarity and DEF color (whereas the industry standards are GHI and SI) to provide you with the most exceptional end piece.

We offer 2 day free insured shipping within USA and discounted international worldwide shipping.

Your satisfaction is out top priority and we offer 30-day complimentary return policy on all of our engagement rings, wedding bands and fine jewelry. Learn more about our full return policy and exclusions at our FAQ.

We stand behind the quality and craftsmanship of our products. Magdalene Pivoine offers a complimentary lifetime warranty against all manufacturing defects.

If you experience any damage to your purchase as the result of the manufacturing, please contact our customer service and we will provide you with the label to ship your piece to us. 

If you are unsure about the ring size, we will send you a free ring by selecting the 'Send me a ring sizer' option when you order the ring. Additionally, we offer complimentary resizing for bridal purchases (engagement rings and non-eternity set rings) within the first six months of delivery, with adjustments of 1 size up or down from the original size to maintain the ring’s integrity. Any additional resizing will incur a charge.
