Frequently Asked Questions

Helpful answers about ring styles, stone shapes, settings, sizing, stacking and caring for moissanite and gemstone rings.

What types of rings are included in the STDIAM Rings collection?

The collection brings together a range of styles including solitaire, halo, three-stone, bezel, vintage-inspired, multi-stone and coordinating ring-set designs. Available styles continue to evolve as new pieces are introduced.

What is the difference between moissanite and lab-grown gemstone rings?

Moissanite is known for bright light return and crisp brilliance, while lab-grown gemstones such as ruby, emerald and alexandrite introduce distinctive color and character. The right choice depends on whether you prefer a colorless focal stone or a more expressive gemstone look.

Which stone shapes are available for rings?

STDIAM rings are available across cuts including oval, round, pear, emerald, cushion, marquise, radiant, princess and Asscher. Each shape changes the face-up proportions of the stone and the overall character of the finished ring.

How do I choose the right ring size?

Measure the finger you intend to wear the ring on and consider whether the design has a slim, wide or stacked profile. Finger size can also change slightly throughout the day. For step-by-step measuring methods, visit the STDIAM Ring Size Guide .

Which ring settings work well for everyday wear?

Each setting creates a different balance of profile and stone exposure. Bezels surround more of the stone, while prong settings leave more of it visible. Halo and multi-stone designs create additional visual presence. Consider your daily routine, preferred profile and maintenance expectations when choosing.

Can STDIAM rings be paired with wedding bands or stacked?

Many rings can be styled with straight, pavé, curved or shaped bands. Whether two rings sit completely flush depends on the centre setting and gallery height, while a small intentional gap can also create a refined layered composition.

How should I care for a moissanite or gemstone ring?

Clean most rings gently with lukewarm water, mild soap and a soft brush, then dry with a lint-free cloth. Avoid heavy impact, abrasive cleaners and harsh chemicals, and inspect frequently worn settings periodically. For more detailed guidance, visit the STDIAM Jewelry Care Guide .

Can I choose different metal tones for my ring?

Available metal tones depend on the individual design. Selected rings may be offered in white, yellow or rose-toned finishes. Check the options on each product page for the finishes currently available for that particular style.
