Four-Prong Moissanite Solitaire Ring

Fugui JewelryRound stone size on a hand

Use this photo to compare the relative appearance of round stones. Other shapes, settings and hand proportions can look different. Check the dimensions of your selected option for the piece you will receive.

Carat labels shown: 0.1–5.0 ct. Compare the selected stone’s dimensions alongside this visual reference.

For the most reliable fit, use a ring sizer or visit a jeweler.

1. Measure the finger on the hand where you will wear the ring.
2. Check that the sizer passes comfortably over your knuckle and fits securely at the base.
3. The illustrated chart below is a general, approximate sizing reference. If measurements differ, the finger circumference listed in this product’s options takes priority.

Measure at a comfortable room temperature and recheck at another time. Band width can change the fit.

The ruler drawing is schematic. Use your own measured finger circumference, rather than the number printed in the illustration.

For the most reliable fit, use a ring sizer or ask a jeweler.

Step 1

Wrap a paper strip around the finger where the ring will sit.

Step 2

Mark the point where the ends of the strip meet.

• Clean gently with lukewarm water, a little mild soap and a soft brush. Rinse and dry thoroughly with a soft cloth.
• Remove jewelry before swimming, bathing, using household chemicals or doing activities that can knock or bend it.
• Store each piece separately in a dry, soft-lined pouch or box.
• Check the setting and clasp regularly. Stop wearing a piece with a loose stone or damaged fitting and contact us.

Silver can tarnish and plated finishes wear over time. Avoid abrasive polishing compounds and harsh chemical cleaners on plated surfaces.

Moissanite Jewelry Care

Cleaning products

Use a mild cleanser, such as a jewelry cleaning solution suitable for your piece or mild soapy water. Avoid bleach, strong acids and strong alkalis that can damage delicate surfaces or metal settings. Never use toilet cleaners, heavy-duty kitchen degreasers or similar harsh household products on your jewelry.

Cleaning tools

Use a soft brush, such as a soft children’s toothbrush. Avoid stiff or abrasive tools to protect delicate surfaces and the setting. Dry with a clean, soft, lint-free cloth, such as a microfiber lens cloth. Avoid rough towels or paper.

Care precautions

During wear. Remove jewelry before strenuous exercise or heavy manual work to reduce knocks that can chip stones or distort settings. Take it off before hair coloring, perming or contact with chemicals. Remove it before hot springs: minerals and other substances in the water can affect the jewelry.

Storage. Store moissanite jewelry separately so that pieces do not rub together. Use jewelry-box compartments lined with soft fabric or foam. Keep the storage area dry; a small desiccant packet can help reduce moisture-related marks and metal discoloration.

Regular checks. Every 2–3 months, check for loose or worn stones, bent settings and changes to the metal finish. Seek professional advice if a stone or setting is loose.
