Understanding Your Stone

A well-informed client makes a better decision. These guides explain what makes each category exceptional — in plain language, without the jargon.

Guide I

What Are Lab-Grown Diamonds?

Lab-grown diamonds are not simulants, imitations, or substitutes. They are real diamonds — created in a controlled environment using the same carbon crystallisation process that occurs in nature. Chemically, physically, and optically identical to mined diamonds.

The two growth methods — HPHT (High Pressure High Temperature) and CVD (Chemical Vapour Deposition) — each produce stones with distinct characteristics. CVD diamonds tend to grow larger and with fewer strain patterns; HPHT stones are often preferred for their nitrogen-free purity.

Recrystallized Emeralds Explained

Recrystallized emeralds are grown from natural emerald material dissolved in a hydrothermal solution and recrystallized under controlled pressure and temperature. The chemical composition is identical to mined emeralds — beryl with chromium and vanadium colouring agents.

What sets them apart from mined stones is their exceptional clarity. Natural emeralds are famous for their inclusions (called "jardin"). Recrystallized stones offer the same vivid green — often more saturated — with a level of clarity rarely seen in their mined counterparts.

Laboratory Paraibas: The Rarest Colour

Paraiba tourmalines are known for their extraordinary neon-blue to electric-teal colour, produced by copper and manganese within the tourmaline crystal structure. Natural paraibas from Brazil are among the most expensive gemstones per carat — rarer than diamonds at similar quality levels.

Laboratory paraibas share the same copper-bearing composition. The colour mechanism is identical, which means the visual result — that unmistakable electric glow — is the same. What differs is the scarcity premium, which in nature is geological, not qualitative.

How to Choose Your Stone

Choosing a gemstone is not just about specifications — it is about what the stone means to you and how it will be used. A stone for a ring that will be worn daily requires different priorities than a stone for a collector or an investment buyer.

Start with category and colour, then refine by size, then by clarity and cut. For diamonds, the classic 4 Cs apply; for coloured stones, saturation and tone take precedence over clarity. Our specialists can walk you through every step.

Common Questions

FAQ

Are lab-grown diamonds real diamonds? +
Yes, absolutely. Lab-grown diamonds have the same chemical composition (pure carbon in cubic crystal structure), the same hardness (10 on the Mohs scale), and the same optical properties as mined diamonds. They are graded by the same laboratories using the same criteria. The only difference is their origin.
Do lab-grown stones hold their value? +
Lab-grown diamonds have stabilised in pricing over recent years. They are purchased for their quality, beauty, and the value they offer compared to mined equivalents. If long-term investment is your primary goal, we recommend discussing this openly in your consultation — we will give you an honest assessment.
Can you tell a lab-grown diamond from a mined one? +
Not with the naked eye, and not with standard jeweller's tools. Only specialised laboratory equipment (such as De Beers' DiamondView) can distinguish them. All certified lab-grown diamonds are laser-inscribed to disclose their origin — which we view as a mark of transparency, not a caveat.
What is the difference between recrystallized and synthetic emeralds? +
Recrystallized emeralds are grown from natural emerald material (dissolved and recrystallized), so they share the same chemistry. Synthetic or flux-grown emeralds may use different precursor materials. We specify the growth method for every stone we offer, so there is no ambiguity.
How long does the ordering process take? +
For stones currently in our inventory, the process from consultation to delivery typically takes 5–14 business days. For custom sourcing or specific requests, allow 2–4 weeks. We keep clients updated at every stage.
