Welcome to Kallos Diamond Exchange

At Kallos Diamond Exchange, we specialise in both lab-grown and natural diamonds — delivering wholesale pricing that consistently beats the market.

We’re not about smoke and mirrors — just real value, genuine stones, and complete transparency.

Every diamond we sell includes full certification details, including certificate numbers and complete specifications.

If you find a better price elsewhere, simply send the certificate number and a screenshot of their quote — we’ll match it or beat it. Guaranteed.

Unbeatable Pricing

Our promise is simple: we don’t mess around on price.

You’re dealing directly with a wholesaler, not a middleman. No inflated margins. No nonsense.

Just the best diamonds at the best possible price.

Custom & Bespoke Jewellery

While our main focus is diamonds, we also create custom and bespoke jewellery — from breathtaking engagement rings and wedding bands to elegant chains and earrings.

If you’re looking for a specific diamond, whether lab-grown or natural, or want a custom piece designed around your stone, get in touch directly.

Tell me what you’re after — size, shape, budget, or even a reference photo — and I’ll help you source or build exactly what you want.

You’ll get honest advice, real options, and wholesale-level pricing without the retail markup.

The 4Cs of Diamonds

Understanding the 4Cs helps you know exactly what you’re buying — no hidden surprises.

Cut: How well a diamond has been shaped and faceted. The cut determines brilliance and sparkle.

Colour: Graded from D (colourless) to Z (light yellow or brown). The less colour, the higher the grade.

Clarity: Refers to natural inclusions or blemishes. Grades range from Flawless (FL) to Included (I).

Carat Weight: The diamond’s size. Larger stones are rarer — but quality and cut matter just as much.

Diamond Appearance Disclaimer:
Every diamond listed on Kallos Diamond Exchange is independently graded by a recognized laboratory (e.g., GIA, IGI) and accompanied by its certification. Diamond clarity and color can vary in visual appearance even within the same grade.

Some diamonds, particularly in lower clarity or color grades, may display visible inclusions or a slight color tint under certain lighting or magnification. These natural characteristics are typical of genuine diamonds and contribute to each stone’s unique beauty.

For clients seeking a guaranteed eye-clean or colorless appearance, we strongly recommend our Hand-Selection Service, where a gem expert personally inspects and approves each stone prior to shipment.
