Welcome to the world of jewelry!  It's a fun place to be. 

There’s a lot to think about when it comes to jewelry, isn’t there?

Let’s cover the basics, shall we.  We are a company that loves our craft and believes in sustainability!  Yes, we recycle metals, I bet you're glad to know that. We love to help our clients upcycle their existing jewelry.  Why wouldn't you?!  And, we only source Conflict Free Diamonds!  By the way, our diamonds are certified.  We've also taken it a step further.  We were one of the first Boston based companies to embrace sustainable, Laboratory Grown Diamonds!  And yes, our Laboratory Grown Diamonds are certified too.  Phew, I bet you’re glad to know all that. 

But these days, jewelry isn’t just jewelry.  There’s more to it.  Let’s explore a little.

No matter which method you choose, we provide you with a level of customer service unmatched in the industry. Whether you are shopping for the engagement ring of a lifetime, a gift for that special someone, or a treat for yourself, this will be a unique shopping experience.

Welcome to the world of jewelry.  It’s a fun place to be! 


Jewelry is a blend of nature, science, technology, art, craftsmanship and the knowledge to understand it all. 

Nature creates the basis for the beauty that we craft into jewelry.  It includes everything from the metals we use to the natural diamonds and gemstones we covet. 

But over the years, just as technology has changed everything else in our lives, jewelry is no different.  Without technology, the modern jewelry industry wouldn’t exist. 

Technology gives us the ability to create CAD imagery and three dimensional prints of our custom jewelry designs.  We can bring your ideas to life in ways we never could before!  And modern technology can teach us about one of nature’s most incredible treasures, the diamond.  It allows us to make the most out of its beauty with exceptional cutting practices, It also allows us to look deeper into these gems and grade them more precisely.  We can even laser inscribe your diamond.  And, we can even create you a diamond. 

Science and modern technology have perfected the art of creating beautiful Laboratory Grown Diamonds that have all the same physical characteristics as a natural diamond, but they’re grown by choice, instead of by chance.  We think there’s room for everyone in our modern family, so we’ve welcomed them into the fold.  It takes skill to understand them and we have it.

Let’s not forget about the artists among us.  The creatives who see what others cannot, those who create and inspire!  Artistry is what turns these natural and new materials into the works of art that we proudly create, share and wear. 

And craftsmanship…that hard won handiwork that goes into making these gorgeous pieces is no small feat.  Sometimes you have to travel half way around the world to find the right person for the job.  And we do that.  Sourcing the right skill for the right piece is as much of an art form as crafting the piece itself.

What about the old treasures you may ask?  The vintage works or a dated piece form a decade gone by?  This is where the art of “Re-Imagining” your jewelry starts to take shape.  It’s a specialty of ours. Use your imagination.  That old piece of inherited jewelry can take on new life with a little bit of creative ingenuity.  Diamonds and gemstones can be “Re-Imagined” back to life.  And sometimes expert restoration and repair might be what's necessary.  All available to you, all with trusted skill and precision.

The last piece is the most important.  Knowledge.  Knowledge is the understanding of how all of these pieces complement each other and work together.  And that’s what has led you to us.  We’re here to guide you every step of the way. From navigating the technology to understanding what works best for your lifestyle and budget. 

There is much to consider and we're here to help.
