About Rare Fine Jewels
Beauty in a brighter world.
RARE FINE JEWELS brings a manufacturing perspective to fine jewelry: thoughtful proportions, solid gold and lab-grown diamonds, made for the person who will wear them.
From Surat, with a closer view of the craft.
Founded by Tatva Sanghvi, our studio draws on a background in jewelry manufacturing in Surat, India. It is a city built around diamonds, and the place where our pieces are designed and made.
We begin with the shape: how a ring sits on the hand, how a bracelet moves, how a setting frames its stone. Designs are developed in CAD before moving through casting, hand-setting and finishing.
Solid gold. Considered detail.
We work in solid 14K and 18K gold, in the colors offered for each piece. Our diamond jewelry uses lab-grown diamonds. We focus on clean lines and pieces that bring something distinct to the everyday.
Made for your order.
Your chosen metal, color and size guide what we make. Take time to explore the options, check your measurements and ask us about the details that matter to you. For stone specifications and the documentation included with a particular piece, contact us before ordering.

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.
