Custom Design
Your ring, designed from scratch.

Because Brisbane Diamond Company sources diamonds at wholesale, the budget goes further than a retail jeweller. Clients choose from thousands of certified loose diamonds and work directly with the designer until every detail is right.
- Select your diamond from a curated range of GIA-certified stones
- Choose metal: platinum, 18ct white gold, yellow gold, or rose gold
- Work one-on-one with the designer to refine every detail
- Receive a finished ring, handcrafted and certified
The Diamond Buying Guide
How do you choose the right diamond?
Buying a diamond is one of the most personal purchases you will make. Brisbane Diamond Company makes the process clear, honest, and confident.
Cut
Cut determines how a diamond interacts with light. A well-cut stone returns light brilliantly, regardless of carat weight. Brisbane Diamond Company grades every stone on cut quality before selection.
Colour
Colour grades run from D (colourless) to Z (light yellow). Brisbane Diamond Company stocks a full range and advises on which grades offer the best value for each setting type.
Clarity
Clarity measures internal inclusions and surface blemishes. Brisbane Diamond Company only sources stones where inclusions are either absent or not visible to the naked eye.
Carat
Carat is a unit of weight, not size. The right carat depends on cut, shape, and setting. Brisbane Diamond Company helps clients find the size that suits both the hand and the budget.
