Tanzanite Rings with a Round Cut Stone

Tanzanite is one of the rarest naturally occurring gemstones - found only in a small region of Tanzania - and its colour is unlike that of any other stone. At its depth, it moves between violet, blue, and a hint of burgundy depending on the light, a quality that the round cut draws out particularly well. The faceting of a round stone maximises colour depth and brilliance, letting tanzanite's natural shift in tone show at its fullest.

It is precisely this rarity and depth of colour that makes a tanzanite ring a meaningful choice, whether as a gift, a personal milestone, or simply a piece that reflects who you are.

Our collection includes a variety of styles, from solitaire settings that let the stone's colour take the lead, to halo designs where the tanzanite is framed by diamonds for added brilliance. We consciously craft every ring from recycled precious metals, with options across white gold, yellow gold, platinum, and silver. Each piece features ethically sourced tanzanites, often paired with conflict-free natural diamonds or lab-grown diamonds that match them in brilliance and beauty.

Browse our collection and find the round tanzanite ring that captures both the colour you love and the moment it marks.

Frequently Asked Questions

How do I know what size ring I need?

+

Getting the right ring size is key to comfort and fit. You can order our free ring sizer (https://www.thediamondstore.co.uk/pages/free-ring-sizer-form) or use our ring size guide (https://news.thediamondstore.co.uk/general-jewellery-learning/rings/how-measure-ring-size/) and app (https://www.thediamondstore.co.uk/pages/ring-sizer) to measure an existing ring at home. If you’re buying an engagement ring in secret, a good tip is to borrow a ring your partner already wears (on the correct finger if possible) and measure it or ask a close friend or family member for help. Our team can also guide you on choosing the best size, and in many cases, rings can be resized later if needed.

Can I have my ring resized?

+

In most cases, yes. Many of our rings can be resized depending on the design and setting. Classic diamond rings, wedding bands, and engagement rings are often resizable, while certain eternity bands or intricate styles may not be.

Once your ring is returned to us, if resizing isn’t possible, we’ll simply issue you a replacement ring in your desired size. This is the best solution for most orders.

However, if you would prefer to have your original ring resized, usually for sentimental reasons, please let our Customer Service team know when you get in touch. We’ll do everything we can to accommodate this request and keep you updated throughout the process.

Can I have a ring engraved?

+

Yes, we offer ring engraving on selected designs, ideal for adding a personal touch to wedding rings, engagement rings, and special gifts. Popular engraving choices include initials, meaningful dates, or short messages, making your jewellery truly unique. If engraving is available for your ring, it will show as an option to add an engraved message on the product page.

Can I use any of your rings as a wedding or engagement ring?

+

Yes - your ring should be as unique as your love story, so you can choose any design from our collection to represent it. Many of our rings, from classic diamond solitaires to eternity bands and gemstone styles, are perfect for both weddings and engagements. Whether you prefer a timeless design or something modern and distinctive, our rings are crafted to symbolise love, commitment, and a lifetime together.

Can I wear your rings all the time?

+

Our rings are crafted with high-quality materials, designed to be durable enough for everyday wear. However, to keep your ring in the best condition, we recommend removing it during heavy manual work, gym sessions, or when using strong cleaning products. Some gemstones, such as emeralds or opals, are more delicate due to their hardness rating and are better suited for occasional wear. But with the right care, your ring will shine for a lifetime.
