Natural & Lab-Grown Diamonds

Two Origins. One Personal Choice.

Every diamond represents something personal.

At Tesha Jewels, selected jewellery is available with both Natural Diamonds and Laboratory-Grown CVD Diamonds, allowing you to choose according to your preferences, priorities and budget.

We believe neither choice should be made for you.

Our role is to provide clear information so you can choose with confidence.

Created by Nature

Natural diamonds are formed through geological processes deep within the Earth over an extraordinary period of time.

They are mined, cut and polished before being selected for use in fine jewellery.

For many clients, the natural origin, rarity and individual history of a natural diamond form an important part of its appeal.

Created Through Advanced Technology

Laboratory-grown diamonds are created under controlled laboratory conditions using technology that recreates conditions under which diamond crystal can develop.

Tesha Jewels offers selected CVD — Chemical Vapour Deposition — laboratory-grown diamonds.

Laboratory-grown diamonds have essentially the same crystal structure and fundamental physical and optical properties as natural diamonds, but their origin is different.

They should therefore always be clearly identified as laboratory-grown.

WHAT IS THE DIFFERENCE?

The fundamental distinction is origin.

NATURAL DIAMOND

Formed naturally through geological processes within the Earth.

LABORATORY-GROWN DIAMOND

Created in a controlled laboratory environment using advanced technology.

Both can be cut, polished and graded for characteristics such as colour and clarity.

Their origin, market characteristics, availability and pricing can differ significantly.

Tesha Jewels will clearly identify whether the diamond you are purchasing is Natural or Laboratory-Grown.

OUR DIAMOND QUALITY RANGE

Depending on the selected jewellery and availability, our diamond offering extends from:

D · E · F · G · H

Our standard offering does not extend below H colour.

TRIPLE EXCELLENT — 3EX

Triple Excellent — 3EX

Excellent Symmetry

The exact characteristics of an independently graded diamond should always be confirmed from its individual laboratory report.

WHICH SHOULD I CHOOSE?

There is no single answer that is right for every client.

A Natural Diamond may appeal to you if natural geological origin and rarity are important parts of what you value.

A Laboratory-Grown Diamond may appeal if you prefer a different balance of size, specification and price.

Your decision may depend on:

  • Origin
  • Carat weight
  • Shape
  • Colour
  • Clarity
  • Budget
  • Personal preference

The choice belongs to you.
