"This cup is the new covenant in my blood, which is poured out for you." – Luke 22:20

More than a piece of jewellery, it serves as a reminder of the promises we make, the faith we carry and the legacy we leave behind.

Special Gifts: An ideal choice for anniversaries, birthdays, milestones and meaningful celebrations.
Everyday Wear: A bold yet refined accessory designed to complement your individual style.
Finding the right fit is important. MATAI Rings are measured using US ring sizes. We recommend checking your measurements carefully before placing an order, as tungsten carbide rings cannot be resized.

Measurements and AU/UK conversions are approximate. Sizing charts may vary slightly between manufacturers and jewellers.
1. Using an Existing Ring
Choose a ring that fits the intended finger comfortably. Measure the inside diameter in millimetres, from one inner edge to the other. Compare your measurement with the diameter column above.
2. Measuring Your Finger
Wrap a thin strip of paper around the base of your finger. Mark where the ends meet, then lay it flat and measure the length in millimetres. Compare this measurement with the circumference column above.
3. Visit a Professional Jeweller
For the most accurate measurement, we recommend visiting a local jeweller to have your finger professionally sized using US ring measurements.
Tungsten carbide rings cannot be resized after manufacturing.
Measure the finger on which you intend to wear the ring.
Finger size can change throughout the day due to temperature and swelling.
Wider bands can feel tighter than narrower rings of the same size.
If your measurement falls between two sizes, seek professional sizing advice before ordering.
Please confirm your size carefully before purchasing.
To maintain the appearance of your MATAI Covenant Ring:
Clean gently using a soft cloth, mild soap and warm water.
Avoid harsh chemicals, abrasive cleaning products and prolonged chemical exposure.
Remove your ring before activities involving heavy impact or excessive pressure.
Store separately from other jewellery to help preserve its finish.
Although highly scratch-resistant, tungsten carbide can chip or fracture if subjected to significant impact.
Ring Resizing: Tungsten carbide rings cannot be resized. Please ensure you select the correct size before purchasing.
Natural Wear: While tungsten carbide is highly resistant to scratching, surface finishes and decorative inlays may experience wear over time.
Product Appearance: Slight variations in colour and appearance may occur due to lighting, photography and screen settings.
