  • Jewelry Cleaning:
    Old jewelry that sees lots of wear will show its age over time. Blemishes, tarnished areas, loose stones, scratches and more will all detract from the beauty of your pieces. Bring them to us for cleaning and we’ll restore the shine and luster of your metal and stones, so your piece looks as good today as it did 10, 20 or even 100 years ago!

Jewelry Style Types

I have developed five primary, conflict-free jewelry style types which are fairly well defined and within them are variations which can be better refined. Along with pictorial examples I listen to the customer key words. I’ve found many people want ethical jewelry either perfectly balanced or asymmetrical – either petite and dainty or bold and dramatic – either the newest daring look or a classic well-tailored appearance.

Ethical Jewelry


A quality look that is timelessly good yesterday, today and tomorrow. Balanced, dainty, petite, detailed with minimal metal work.

Conflict-Free Jewelry


A softer flowing line inspired by the natural curves of sails, ribbons or vines. Not necessarily balanced but having movement. Also called art nouveau.

Custom Engagement Rings


A dynamic work of art on your hand. Each detail is carefully chosen for dramatic effect. Great attention to tailored well refined lines. Clean and high polished.

Jewelry Gemstones

Fashion Forward

Young and daring to try the newest style. Not following what has been done but setting the course with new ideas in color, texture, and shape. It is always getting updated. Makes a statement about the wearer and what they like without being pretentious.

Custom Handmade Jewelry

Balancing Act

Asymmetrical, it has a feeling of movement. Odd numbers of stones or elements with different shapes.
