Most diamonds want to be colorless. This one doesn't. A single round brilliant natural cognac diamond sits in a smooth 14K gold collar, glowing the warm honey-amber that only forms underground over billions of years of geological pressure. Not treated, not enhanced, not a lab. The color is the stone.
A single round brilliant natural cognac diamond per earring, graded on the Argyle C1–C7 color scale — the warm brown-amber range that runs deeper and richer than champagne. The color is geological, formed over billions of years under extreme pressure, never treated or enhanced. The bezel puts the full face of the stone on display, nothing distracting the eye from the color. No prongs to catch on hair or sweaters, no flash that telegraphs across the room — just a soft, ambered glow against the lobe.
A full bezel — a continuous rim of gold wrapping the entire circumference of the stone — holds each diamond flush and secure. The smooth rim sits close to the ear, making these ideal for helix and second-hole stacks, sleepers, and anyone who lives in headphones. The cognac color reads as a warm neutral that works against yellow, rose, and white gold without losing its character, and it doesn't fight whatever else is in your ears that day. Posts and butterfly backs are solid 14K gold throughout.
Available in solid 14K yellow gold, 14K white gold, and 14K rose gold. Yellow gold amplifies the warmth of the cognac. White gold creates contrast, making the brown of the stone announce itself. Rose gold echoes the warm frequency of the diamond for the softest, most wearable of the three. Posts and backs are solid 14K gold throughout — no plating, no shortcuts. All gold options are nickel-free and safe for sensitive skin.
Each pair is built to order at our Woodside, Queens workshop by founder Dimitri. The bezel cups are formed and seated by hand, the diamonds set under the loupe to sit dead-center in the collar, and the posts soldered and finished one pair at a time. Production takes 1-2 weeks from order confirmation. Ships free, fully insured, signature required on delivery. Lifetime manufacturing warranty. Call or text 929-806-1502 with any questions.

Arrives gift-ready
Every Brownstone piece ships in our signature cream suede pouch, embossed with the Black Pearl of Queens mark. Polishing cloth and care card included. No extra wrapping needed — it arrives exactly as it should be given.
Cognac and champagne diamonds are natural fancy color diamonds graded on the Argyle C1–C7 scale. The warm amber-brown color is formed over billions of years through geological pressure — not treatment, not enhancement, not a lab. Every stone is one of a kind. The color that takes billions of years to form is the color you wear every day.
Champagne diamonds (C1–C4) range from pale gold to deep honey. Cognac diamonds (C5–C7) are deeper amber-orange. Every stone is graded before setting. No two are the same shade.
14K brown gold is our signature Brownstone alloy — stone and metal become one continuous cognac tone, nothing else reads like it. Yellow gold amplifies warmth and works with every grade. White gold creates bold contrast, making cognac stones announce themselves. Rose gold and champagne diamonds share the same warm-pink frequency — soft, luminous, quietly luxurious. Platinum is the most formal and the most durable.

Every diamond in the Brownstone Collection is a natural diamond. The complex warm color comes from physical crystal structure that cannot be replicated in a lab.
You can measure your ring size using a ring sizer tool or by wrapping a thin strip of paper around your finger and measuring the circumference. Best measured in the evening when fingers are at their largest. Use our ring size guide for full instructions.
Ring prices vary because each size requires a different amount of precious metal. Larger sizes use more solid gold, which affects the price. All pricing is transparent at checkout.
