The most useful first conversation is specific. Send the desired diamond size, color target, timeline, whether the request is for a finished gem or rough material, and whether you need a one-off project or a production route.
The important distinction is that Carat's gem work is tied to actual plasma CVD diamond growth capability. That matters when the project requires custom growth, provenance, unusual size or color goals, or a production system discussion rather than a retail inventory search.
For finished jewelry purchasing, use the gem inquiry path. For technical single crystal material, use the technical diamond products path. For production equipment, start with the deposition systems page.

Gems grown at Carat Systems.
Carat Systems is developing Humanite™, a new form of personal CVD diamond. The concept is simple: a small amount of meaningful carbon-bearing material from a person, object, or moment can be prepared and incorporated during diamond growth.
The result is not only symbolic. It is physical. The diamond contains material connected to the story behind it, while still being grown through a controlled CVD diamond process.
Humanite™ is separate from memorial ash diamonds and HPHT conversion concepts. The focus is positive life events, commitments, achievements, and meaningful objects translated into individually grown CVD diamond.
A diamond. Your story. Forever.
Humanite™ is offered by referral only, with a limited number of commissions each year.
If your goal is a custom grown stone, the useful question is not only carat weight. The growth plan must account for seed size, target shape, color objective, cut plan, yield loss, and post-growth processing. A short technical review avoids unrealistic assumptions.
If your interest is single crystal diamond as a material rather than a jewelry product, Carat can review plate dimensions, thickness, polishing, optical or electronic requirements, and whether CVD diamond growth or material supply is the best route.
