Custom Design

Get Started

“Oh This? It’s One-Of-A-Kind.”

All our jewelry is magic, but there’s something so undeniably special about a custom engagement ring or piece of jewelry. Our design specialists and Master Jeweler are experts at bringing your personal vision to life within your budget. We make the entire process educational, fun and easy. So let’s get started!

Your Imagination, Our Ingenuity

Your Imagination, Our Ingenuity

Meeting either in person or virtually, we’ll start with what inspires you, reviewing any pictures or sketches you have and offering ideas of our own. Once we’ve gone over every single detail, we’ll confirm a quote for your custom design before moving forward.

Visualizing Your Dream

Visualizing Your Dream

We’ll create a CAD rendering, a detailed sketch or a live model to show you exactly what the end result will look like — so there are no surprises (except, perhaps, how instantly obsessed you are).

The Hunt Begins

The Hunt Begins

Our gemologists hand select every one of our conflict-free and ethically sourced diamonds and gemstones personally from trusted sources. We go way beyond reports to consider value, quality and proportion—always putting your budget and priorities first.

Responsible sourcing is at the heart of what we do

Here’s what you need to know: First, we only work with trusted manufacturers who provide conflict-free diamonds and gemstones mined in accordance with strict standards for environment and social responsibility.

We go above and beyond the GIA report and 4 C’s, carefully assessing the quality of the rough, proportions of the stones and nature of the inclusions, all of which impact the beauty and value of a stone. And throughout the entire process we work one-on-one to ensure we find the stone that’s best tailored to your budget and priorities. Think of it as stone sourcing with a soul.

Why We Use Recycled Metals

Why We Use Recycled Metals

We believe in creating jewelry you can look good wearing and feel good owning. The majority of recycled gold we use within our shop and when creating our collections is purchased from SCS Certified Sources. SCS, or Scientific Certification Systems is an organization dedicated to ensuring that their partners utilize conflict-free recycled metals and ethically sourced gemstones. To obtain a SCS certification, suppliers must meet fundamental benchmarks of social and environmental accountability by: practicing risk management throughout their supply chain, treating workers fairly according to international labor standards, and abstaining from destructive environmental practices while mining precious metals.
