Conflict-Free Diamonds

At bluboho, every diamond we source is conflict-free strictly aligned with the Kimberley Process certification. We partner closely with experienced suppliers to ensure each gem comes from a place where workers are treated fairly and responsibly.

Recycled & Antique Diamonds

Looking for something uniquely meaningful? We offer recycled and antique diamonds that have been gracefully reclaimed, re-cut and polished, ready to shine again in a new engagement or fine jewelry piece. These ethically-sourced gems carry a story, a history—and a premium for their craftsmanship and rarity.

Unexpected & Distinct Diamond Styles

Not just white brilliant-cuts. Explore our collection of rose-cut white diamonds, black diamonds and grey diamonds—beautiful alternatives that deliver character and elegance for a non-traditional engagement piece.

When choosing an engagement ring diamond, many begin by evaluating the “Four Cs”: Cut, Clarity, Colour, and Carat. While at bluboho we believe in beauty, durability and emotional resonance above all, it’s still helpful to know these basics.

Cut

The “cut” of a diamond refers to how the rough gem has been shaped and faceted to maximize brilliance. At bluboho we carry styles including:

Round Brilliant: the classic sparkling choice

Rose Cut: soft, romantic and candle-lit in appearance

Marquise: elongated, elegant and flattering

Baguette: clean, rectangular and modern

Few diamonds form without any inclusions or internal characteristics—less than 1%. Rather than call them “imperfections,” we embrace these natural traits because they add character and uniqueness to each stone.

I1, I2, I3 (“Included”): Inclusions are obvious, may be visible to the naked eye

SI1, SI2 (“Slightly Included”): Inclusions visible at 10× magnification, often “eye-clean” and excellent value

VS1, VS2 (“Very Slightly Included”): Minor inclusions, typically not visible without magnification

VVS1, VVS2 (“Very, Very Slightly Included”): Extremely rare, minimal inclusions visible only under magnification

Most of the stones we select fall into that “sweet spot” where inclusions are minor, the diamond sparkles beautifully, and value remains strong.

Colour

White diamonds are graded from D (colourless) to Z (light yellow or brown). Please note this scale applies only to white diamonds—black, grey or champagne-diamonds follow different systems.

Carat

Carat weight refers to the gem’s weight, not necessarily its diameter. Because cut and setting can affect footprint, carat is a guide—rather than guarantee—of size.
