Platinum Round Bun, Moissanite Diamond Ring

Your Rivrun piece is crafted with precision moissanite diamond and lab-grown premium gemstones, set in S925 sterling silver or hallmarked 18K to 22K gold.

To keep its brilliance everlasting:

Avoid harsh chemicals like: Bleach (Sodium hypochlorite), Chlorine (found in swimming pools), Acetone (nail polish remover), and moisture. These chemicals can tarnish gold and silver, and gradually dull the radiant sparkle of your jewelry in some cases, even reduce the metal weight over time through slow corrosion.

While moissanite and diamonds themselves are incredibly durable and resistant to most chemicals, their brilliance can still appear dull if residue from perfumes, soaps, or cleaning agents builds up on the surface. This film blocks light reflection making the stone look cloudy instead of sparkling.

That’s why we always recommend:
✨ Cleaning your jewelry gently with mild soap or with your face wash, warm water, and a soft brush.✨

Proper care ensures your moissanite diamond, lab diamond, and precious metal jewelry continues to shine with its original brilliance year after year.

✨ Everyday Care & Longevity Tips

Remove your jewelry before swimming, exercising, or sleeping to protect it from unnecessary wear and exposure to moisture or impact.

Store each piece separately in a soft pouch or a lined jewelry box — this prevents scratches, tangles, and keeps your brilliance intact.

For lasting shine, schedule an annual professional inspection. A trusted jeweler can check for loose settings, worn prongs, and professionally repolish your moissanite or lab diamond jewelry — restoring its like-new glow year after year.

With this simple care, your Rivrun jewelry will continue to sparkle beautifully just like the day you first wore it.

We ensure your jewelry reaches you quickly, safely, and beautifully packaged.
