Mint & Lily jewelry is made with a variety of fine materials. Many of our designs allow you to choose between our Surgical-Grade 316L Stainless Steel products or our Demi-Fine 925 Sterling Silver or 18k Gold Vermeil.

What are your Surgical-Grade 316L Stainless Steel products made out of?

  • The base material for these products is Surgical-Grade 316L Stainless Steel
  • Optional finishes include Genuine 18k Gold plating and 18k Rose Gold plating
  • Quality materials designed to never fade, rust, tarnish, corrode, or stain
  • Water-resistant and suitable for wearing anywhere and everywhere
  • Hypoallergenic, nickel-free casted material so our pieces will not irritate or discolor

What are your Demi-Fine 925 Sterling Silver or 18k Gold Vermeil products made out of?

  • The base material for our Demi-Fine / Sterling Silver products is 925 Sterling Silver. These products feature an e-coat to help prevent tarnishing.
  • 18k Gold Vermeil products start with a base material of 925 Sterling Silver and are coated with a thick layer of real 18k Gold plating for the experience of pure 18k Gold at a fraction of the cost.
  • 925 Sterling Silver jewelry contains 92.5% silver, which means it will be less likely to tarnish. 

Jewelry Care

Our 316L Stainless Steel based jewelry is tarnish and water resistant. Avoid contact with strong chemicals and cleaning agents (detergent, bleach, perfume) as these solutions may damage the layer of gold or silver plating and will cause tarnishing or discoloration. 

Keep your jewelry pristine and clean by wiping them down with a scratch-free cloth for a smudge-free shine. You can use mild soap and room temperature water with a soft cloth to cleanse your jewelry. Dry completely before storing. To remove tarnish from 925 Sterling Silver jewelry, use a mild solution of baking soda and water. 

Your jewelry will be delivered in a Mint & Lily box perfect for gifting! 

We start working on your order as soon as it is placed.

Personalized jewelry cannot be returned or exchanged as each piece is customized for you!

Non-personalized item(s) can be returned to us within 75 days of your purchase. After 75 days, unfortunately, we can’t offer you a refund or exchange. 

We strive for 100% customer satisfaction so if you’re unhappy for any reason with any order order we ask that you reach out to our customer service team. Email us at  and we will work with you to make things right.

Need help finding your ring size?

Use a piece of string to measure around the bigger knuckle on the finger you want to wear the ring on. Wrap the string around the knuckle loosely and mark the string with a pen or marker.

Measure the length of the string to your mark on a millimeter ruler. Try to lay the string flat on a surface beside the ruler without stretching it. If the string is a little curly, try wetting it so it lays straight.

Find your measurements in the chart below to find your nearest ring size! Our rings are adjustable (with a little gentle pressure), so if you fall in between sizes, we recommend going with the size that is closest to your measurements.

Super cute and Dainty

I love my ring! It looks great! Only thing is is gets stuck in my hair sometimes. Not enough to hurt. Just enough to move the hair out of place. I also scratched my face when I was putting my moisturizer on the first day I was wearing it. So it took alittle getting used to. But i haven’t taken it off since I got it.

Very happy

The ring is exceptionally comfortable to wear, and the stones are smoothly set, so it doesn't snag on clothing. The black diamonds sparkle brilliantly, especially in natural light, making it an attention-grabbing piece that draws compliments from all around.
