Peg and her husband Jim (shown right) wanted something special for her engagement ring, so they picked this amazing square cushion cut pink Chatham champagne sapphire set in a spectacular diamond studded mounting. Chatham pink champagne sapphires have gentle hues of lilac pink. Peg couldn’t be happier with her gorgeous ring!

Top color and quality backed with a warranty

Chatham Created Emerald Cut EmeraldsAll Chatham gems are grown using a method that best replicates the crystal growing process deep within the earth. Chatham simply creates the environment in which the gems can grow, and nature takes over. Only trained gemologists with magnification can tell the difference between Chatham-grown and mined gemstones. Because Chatham crystal growth is more predictable and consistent, their method yields the finest qualities and colors found in nature at a much lower price. Diminish your carbon footprint by featuring a Chatham-created center stone in your custom jewelry piece.

Trust, integrity, and value are at the heart of Chatham. For your peace of mind, we provide a lifetime warranty on Chatham stones. A small bi-fold included with your purchase certifies the stones authenticity and details the warranty.

Consider using our Custom Jewelry Design services. Peg and Jim chose us to create this beautiful engagement ring: “Ok this ring is gorgeous !  The diamonds add a sparkle, definition and importance to the center stone.  The sapphire is different colors under different light.  Interior lights make it a bit more pink/champagne and exterior, natural light is a very pale pink and violet.  Bright light is violet.  It is amazing to watch it change! Regarding the design, it is a mixed bag of opposites:  It’s bold and yet demure, it is classy and yet modern, it is both vintage and new, it is changing yet classic….do I sound happy about it? You bet I am.  And Jim loves it.”

Our Work In Madagascar

Changing lives for children and their families

We get our hands dirty!

In 2014 Michelle went to Madagascar to learn about the geology and mineralogy of the country. She was excited to visit some of the mining localities she learned about in her studies to be a Graduate Gemologist. However, it wasn't the sparkly colorful gems that caught her eye. Rather, it was the children...the little gems of Madagascar. Michelle founded in 2015. She visits Madagascar for about two months each year doing humanitarian projects, including clean water, sanitation, education and hygiene.
