There are blues that take your breath away — and then there is this. 💙

A 0.70 Carat + Natural - GIA Graded - Fancy Intense Blue - Pear Modified Brilliant Cut Diamond with a VS2 clarity.

A color so rare, so deeply saturated, it feels less like a gemstone and more like a captured moment of sky, sea, and time itself. 💫

Fewer than one in every hundred thousand diamonds earns a blue color grade from the GIA. To reach Fancy Intense — that is something else entirely. A depth of color that nature produces only once in a great while, and only for those lucky enough to find it.

Some things are simply meant to be treasured. 💙

Presenting — The Ember & Earth ✨

Some things in nature are so rare, they feel like they were never meant to be found. A Fancy Deep Orangy Brown diamond is one of them.

Deep within the earth, over billions of years, a perfect storm of pressure, heat, and trace elements conspired to create one of the rarest color grades in the diamond world. Less than a fraction of a percent of all diamonds ever mined carry this extraordinary depth of color — a living ember, warm and alive.

This Natural 10 Carat + GIA Pear Modified Brilliant Cut is the heart of *The Ember & Earth* — a one-of-a-kind slide pendant crafted in 18 Karat Yellow Gold, paired with a unique shield-shaped colorless diamond that is 0.60 Carat + 🛡 that draws the eye and frames the warmth of its partner.

Slide it onto our 18 Karat Yellow Gold Diamond Tennis Necklace — featuring 5+ carats of Natural Round Brilliant Cut diamonds — and you will have something truly unrepeatable.

This is not just jewelry. This is geological history, worn beautifully.

🍀 Happy St. Patrick’s Day from Rio Diamond 💚

Rarer than a four-leaf clover. More vivid than the rolling hills of the Emerald Isle.

Introducing our newest treasure — a Natural Fancy Vivid Green Diamond, Pear Modified Brilliant, graded by the GIA with the pinnacle color designation: Fancy Vivid Green.

🌿 Why is this extraordinary?

Natural green diamonds are among the rarest gems on Earth. Their color isn’t formed by trace elements like most fancy colors — it is the result of natural radiation exposure over billions of years, often penetrating only the outermost layer of the crystal. A deeply saturated, evenly distributed Fancy Vivid Green throughout an entire stone? That’s a geological miracle.

Of all fancy color diamonds graded by GIA, Fancy Vivid Greens represent a fraction of the less than 0.1% of all Fancy-Colored Diamonds — making this pear-cut beauty a true collector’s trophy.

This St. Patrick’s Day, we’re honoring the magic of the Emerald Isle with a gem as wild, rare, and breathtaking as Ireland herself.

Two bracelets. One obsession. ✨

Introducing our curated duo — Fancy Shape Diamond Bracelets set in Platinum and 18 Karat Yellow Gold, crafted for those who understand that true luxury lives in the details. 💫

💛🤍 The first: Yellow Pear Brilliant Cut Diamonds paired with slightly smaller Colorless Pear Brilliant Cut Diamonds — nearly 15 carats of breathtaking brilliance.

💛🤍 The second: Sought-after Yellow Oval Brilliant Cut Diamonds alongside Colorless Round Brilliant Cut Diamonds — over 11.50 carats of pure radiance.

Yellow diamonds are among the rarest treasures on earth. Their extraordinary color comes from nitrogen atoms — present during formation deep within the earth billions of years ago — that absorb blue light and emit that signature warm, golden glow. Fewer than 1 in 10,000 carats mined is a natural fancy color diamond, making each yellow stone a geological miracle as much as a jewel.

These are not just bracelets. They are wearable wonders of nature. 🌍💎
