Carat is weight. Proportions are presence. 💎

A diamond’s carat weight only tells part of the story, dimensions tell the rest. Length, width, depth, and overall proportions all influence how large a diamond appears, it’s finger coverage, and the overall presence it has once it’s set.

Janet personally guides each client through the diamond selection process, comparing stones side by side to find the perfect balance of proportion, brilliance, and wearability and making sure your final choice aligns beautifully with your hand, setting style, and long-term vision.

Old Mine Cut diamond reveal ✨

True heirloom stones with history, character, and presence.

There’s something soulful about an old mine cut. The larger chunkier facets reflect light in broad flashes rather than sharp sparkle, creating that unmistakable old world fire.

Old mine cuts are true connoisseurs of romance. Imperfectly beautiful, deeply individual, and increasingly difficult to find. We would love to help you find yours!!

Perfect for a custom engagement ring, bespoke setting, or one-of-a-kind fine jewelry design.
