Sterling Promise Inc. is a United States-based company that works primarily in New York and New Jersey.
Our company has been creating custom jewelry for over 30 years. With a certified gemologist on our team and hundreds of contacts, we can help you create a unique piece of jewelry from start to finish for the best price! We even offer price matching.
For the first time ever, we are opening our services up to the public. Previously, we only worked with personal referrals but we’re interested in expanding our business.
Engagement rings are our specialty. The first step we take is educating our customers about diamonds and other stones in order for them to make the best purchase that suits their individual needs. Contact us today for a free information packet and a one-on-one consultation.
