Four ways to shine

The Launch Edit

Find your everyday extraordinary.

Explore all pieces

Wedding & custom

Commitment, without the old rules.

Solitaires, pavé bands and matched stacks in solid gold — or a piece designed with you from the first sketch.

Construction

More diamond. Less weight.

Low-profile settings and fine gold structure put the diamond forward and keep each piece light enough to wear every day.

Every RFJ piece is made to order in solid 14K or 18K gold with lab-grown diamonds.

Lab-grown diamonds

Grown in a laboratory — not mined — with the same optical and physical properties as natural diamond.

Solid 14K & 18K gold

No plating, no vermeil, no sterling silver. Choose 14K or 18K in the available colors.

Made to order

Each piece is produced for your order in your chosen metal, color and size.
