01
Design
Many custom projects begin with sketches, reference imagery, or conversations with a client. This stage helps refine proportions, stone placement, and overall design direction before production begins.
THE STUDIO
The Designer
Twenty-two years of timeless design.
Annmarie D’Ercole has spent more than two decades creating jewelry rooted in timeless design, craftsmanship, and effortless wearability. What began as a passion for fine jewelry evolved into a collection known for its understated luxury — pieces designed to feel personal, refined, and meant to be worn every day.
Inspired by natural stones, vintage influences, travel, architecture, and the individuality of the women who wear her designs, Annmarie approaches jewelry with a balance of elegance and ease. Each collection reflects a thoughtful attention to proportion, texture, and timeless style rather than trends.
Natural and lab-grown diamonds, colored gemstones, and one-of-a-kind stones are sourced through a trusted network of longtime suppliers and artisans cultivated over twenty-two years in the industry. From the initial concept to the final finishing details, every piece reflects the quality, authenticity, and craftsmanship that define the Annmarie D’Ercole brand.

A look inside our custom design process.
Every piece begins differently. Some designs start with a sketch, others with a stone, an heirloom, or an idea brought in by a client. Depending on the design, custom pieces may move through several stages of development before the final setting and finishing work is complete.
02
Model
For select custom pieces, a wax or digital model may be created to visualize the design in three dimensions and finalize important details before casting.
03
Casting & Finishing
Depending on the design, pieces may be cast in gold or platinum before undergoing polishing, finishing, stone preparation, and additional detailing.
04
Setting
Diamonds and gemstones are carefully set and finished by experienced craftsmen using a variety of traditional and modern techniques depending on the piece.
The Materials
Solid metals. Certified stones. Hand-finished work.
Metal
Solid 14k gold — yellow, white, or rose — and platinum. Nothing plated. Nothing filled. The metal you can see is the metal all the way through. 18k available on request.
Stones
Natural and lab-grown diamonds, responsibly sourced through a trusted network of suppliers and longstanding relationships the studio has cultivated over the past twenty-two years. Emeralds, sapphires, rubies, opals, tourmalines, and one-of-a-kind stones are carefully selected for their beauty, quality, and character, whether personally sourced by the studio or brought in by clients. Every stone is chosen with an uncompromising attention to craftsmanship, integrity, and authenticity.
Care
Every Annmarie D’Ercole piece is carefully finished, inspected, and packaged before it leaves our hands. From the initial design to the final polish, each piece reflects the craftsmanship and attention to detail that has defined the studio for over two decades. We also offer cleaning, refinishing, sizing, and repair services for Annmarie D’Ercole jewelry to help maintain the beauty and longevity of each piece over time.
Custom Commissions
