Custom design

Contrary to popular belief a custom designed piece of jewelry can be as affordable as a mass produced jewelry. The process begins with conversations about lifestyles, business professions and desire. Counter sketch and ideas are formed, based on these conversations.. CAD design is also available. Diamonds or gemstones are selected and the building of the design begins. Metals are then determined, we can do any metal. Our bench jeweler will hand carve a wax model for your approval. At this point we can weigh the wax and be able to determine finish metal and cost. Start to finish jewelry can be completed in as little time as 10 to 14 days. A Great way to get a unique one of a kind piece of jewelry you will treasure forever.


We are happy to offer appraisals for insurance claims and personal use (free initial appraisal when you buy jewelry from us). Appraisals include; accurate values for repair/replacement, mounting and stone information, detailed description of jewelry.

Can be updated upon request every 2 years.

Appraisal cost will be determined by a time + effort basis
