Do you use recycled gold?

Yes - we use 100% recycled precious metals! We use Hoover and Strong which has pledged to use metals from 100% recycled sources. We also refine our own metals from time to time. The only materials that we use that are not 100% recycled are the rolo chains used on the necklaces. At this time, there is no 100% recycled source for these chains.

Do you offer conflict-free diamonds and sapphires?

I’m so glad that you asked! Mined diamonds and sapphires are fraught with human rights and environmental problems. Even those gemstones that are certified conflict-free cannot be verified if they come from Africa or India. There is a huge lack of oversight in the process and many human rights violations have been uncovered since the implementation of the Kimberley Process - a process that is supposed to prevent such abuses. I am passionate about human rights and I don’t believe that my privilege of owning a business and doing what I love should tread on another human being’s right to live and work freely.

What do you offer as an alternative to diamonds?

I offer post-consumer diamonds and sapphire as well as lab-created or cultured diamonds and sapphires. These are the most ethical stones available and an excellent choice for customers looking for stones that have not been mined. No mining means no environmental damage and no human rights abuses. I get my lab-grown gems from companies who specialize in growing your gems in tightly controlled laboratory conditions in the United States and abroad-Chatham, Charles and Colvard and other independent gemstone dealers. We strongly believe that the current standards set by the Kimberley process for certifying conflict-free diamonds does not go far enough to verify that the sources of diamonds imported into the United States are ethical.

What is Moissanite?

Moissanite was discovered in a meteor in 1893 and was first confused with diamonds due to its brilliance and hardness.  It would be more than 100 years before this stone would be made available for jewelry use thanks to advances in lab-growing techniques.  This amazing stone has greater fire than a diamond and is harder than a sapphire (it reaches 9.5 on the Mohs hardness scale). Moissanite is currently produced in North Carolina by Charles and Colvard. I could go on about it's formation from Silica Carbide and its crystalline polymorphs, but perhaps you'd be better off hearing this from Wikipedia.

Does Lab-grown mean fake?

No. Easy enough, right? The full story is that lab-created stones are created in a lab and mined gemstones are dug up from the ground. Lab-created stones begin with a small bit of carbon, then are subjected to the same pressure and heat that mined stones are subjected to, but time, pressure and heat are compressed to make them grow faster. Lab-created, or cultured gemstones such as diamonds, sapphires and rubies are chemically and physically identical to their mined counterparts. Only a trained gemologist using a high-powered microscope can tell the difference. Cultured diamonds have the exact same hardness, specific gravity and refractive properties as a mined diamond, but at significantly less cost-both human and monetary.

What kinds of metals do you use in your jewelry?

We use genuine sterling silver, 14 karat and 18 karat yellow, rose and green gold, 14 and 18 karat palladium white gold, Palladium 950, and Platinum 950. The metal is indicated in each of the product listings. All of our metals are from recycled sources and we look forward to bringing you Fair Mined metals in the future.

IS sharon Z jewelry LGBTQ-friendly?

Oh hell yes. Love is love is love is love. 🌈

You might see that some of our descriptions say things like 'women's ring' or 'men's ring'. Those descriptions are in there for SEO (search engine optimization) purposes so that people can find us on the interwebs. 

Not for nothing, but in 1996 we wrote letters to our senator urging her to vote against DOMA. We never quite forgave her for voting yes.

What is green gold?

All karat gold is an alloy of pure gold and other metals.  Green gold is an alloy of pure gold and pure silver that produces a delicate light green color.

Is your white gold jewelry rhodium plated?

No. We use only 14 and 18 karat palladium white gold which has a beautiful color and does not need rhodium plating. Palladium white gold is far less yellow than regular white gold and contains no nickel. We don’t think that plated jewelry holds up as well over time and we want you be able to love your jewelry for years to come.

Do you offer hypo-allergenic jewelry? I am allergic to silver and gold.

Yes. I offer jewelry made from Platinum 950 which is alloyed with ruthenium. Both of these metals are in the platinum family and are not usually reactive to your skin.

Does your jewelry contain Nickel?

Happily, no. Nickel is commonly used as an alloy with gold to produce white gold and in many cases elicits an allergic reaction from the wearer. The only white gold that I use is alloyed with Palladium and is nickel-free. Regular nickel white gold is less expensive and is available upon request.

Does Sharon Z Jewelry donate to charities? I’m asking because, well, I’d like a donation.

The answer is yes, but we verify that each charity matches our corporate values of protecting human rights and the environment. We also need to make sure that you are a certified 501 c3 non-profit in order to qualify for a donation. Email us at Please know that while we would like to respond to every inquiry that we receive, there isn’t always time enough in the day to do so. If we are interested in contributing, we will be in touch.

Yikes! I ordered a ring, but I got the size wrong. What do I do?

First of all, don’t panic. Ring resizing is a common request and we regularly perform this service on our rings. Your first ring resize is free of charge (subsequent re-sizings may incur a small fee). If you feel that you may have gotten your ring size (or her ring size) wrong, I highly recommend visiting your nearest local jeweler to have your finger sized by a professional. If you are in the Bay Area, I welcome you to make an appointment with me at my studio in San Francisco’s Union Square District. Email me directly at
