Our name means treasure, find yours here.
We are a proudly family owned and operated private jeweler with over 35 years of combined experience in the diamond and jewelry industry. Our years of expertise will bring an educated approach and unparalleled personal attention. That personal attention is what makes us private jewelers.
Our model is different, we are not your classic jewelry store. There are many ways to work with us. Do you prefer an online shopping experience? Whether you are shopping for diamond studs, a fashion piece or a stunning engagement ring, Tesoro Boston has you covered.
Our newly developed online shopping experience removes the guesswork out of buying a diamond. You choose the setting and then let Tesoro Boston do the work for you, that is what experts are for! Gone are the days of trying to choose from hundreds of online diamond options. We pour over diamonds and compile for you a carefully chosen, hand-selected group of loose diamonds to choose from, all GIA Certified and chosen for their quality and value.
Prefer a more personal approach? Call or email and let us guide you to the perfect piece or design one from the ground up. If you are local to the Boston area, visit our private showroom and buying offices where one on one attention will be the focus of your visit. We encourage you to bring your ideas to the table. Making personal, custom jewelry is what we do best. If you need inspiration, browse our galleries and let us take it from there. If you find the perfect piece along the way, look no further, it's yours!
