FREQUENTLY ASKED QUESTIONS
What is a moissanite engagement ring?
A moissanite engagement ring features a lab-created moissanite center stone known for its brilliance and fire. STDIAM offers moissanite engagement rings in solitaire, hidden halo, three-stone and vintage-inspired settings, with a range of popular stone shapes.
What carat size should I choose for an engagement ring?
The best engagement ring carat size depends on your preferred visual presence, finger proportions and everyday style. Smaller center stones create a more understated look, while larger stones offer greater presence. Stone shape can also affect how large the center stone appears on the hand.
Which engagement ring shape looks the largest?
Compared with a round engagement ring of similar stone weight, oval engagement rings, marquise engagement rings, pear engagement rings and some radiant engagement rings can appear larger because their elongated proportions create more visible face-up surface area. The final appearance also depends on the stone dimensions, proportions and setting.
How do I measure my engagement ring size at home?
Measure your finger when your hands are at a comfortable temperature and avoid measuring immediately after exercise or exposure to extreme heat or cold. Compare your measurement with the STDIAM Ring Size Guide before ordering.
VIEW RING SIZE GUIDE →How should I care for a moissanite engagement ring?
Clean your moissanite engagement ring gently with mild soap, warm water and a soft brush. Avoid harsh chemicals and abrasive cleaners, and remove your ring during activities that could expose it to unnecessary impact or scratching.
Moissanite vs. lab-grown diamond: what’s the difference?
Moissanite and lab-grown diamonds are different gemstones. Moissanite is known for strong brilliance and colorful fire, while a lab-grown diamond has the same crystal structure and optical properties as a mined diamond. The right choice depends on your preferred look, brilliance and budget.
Which engagement ring shapes can make fingers look longer?
Elongated engagement ring shapes such as oval, pear and marquise can create a longer visual line on the finger. Emerald cut engagement rings can also create a refined, elongated appearance, while radiant engagement rings offer a similar lengthening effect with more brilliant-style faceting. The overall appearance also depends on the stone's length-to-width ratio, setting and individual finger proportions.
What engagement ring setting is best for everyday wear?
The best engagement ring setting for everyday wear depends on your routine. Solitaire and lower-profile settings offer a clean, practical look, while bezel-inspired settings can provide additional protection around the stone. Hidden halo and three-stone designs create more detail and visual presence.
Can I pair an engagement ring with a wedding band?
Yes. Many engagement rings can be paired with a wedding band to create a coordinated ring stack. The best fit depends on the engagement ring profile, center-stone setting and band shape. Curved or contoured wedding bands can help create a closer fit around some settings.
Does STDIAM offer a warranty on engagement rings?
Yes. STDIAM engagement rings include a 2-year warranty. Free engraving is also available on eligible designs. Please review the applicable warranty and jewelry care information for full coverage details.
