Diamond Knowledge & Guides
From the creation of a Lab Grown Diamond through the 4Cs to certificates, selection, settings, and jewelry care: in-depth knowledge for an informed jewelry decision.
Your Digital Diamond Library
Diamonds are easier to select when technical terms are easy to understand. That is why we have organized our knowledge into clearly structured subject areas—from the first steps in understanding to the specific purchase decision.
Where Would You Like to Begin?
Four central topics take you directly to the fundamentals of Diamond selection.
What Defines a Lab Grown Diamond?
Start with the basics: what a Lab Grown Diamond is, how it differs from a natural Diamond, and which widespread myths do not stand up to closer examination.
How Are Lab Grown Diamonds Created?
CVD and HPHT are the most important technical growth methods. Learn about the journey from Diamond seed to cut and certified Diamond.
How to Read Quality Correctly
Carat, Cut, Color, and Clarity form the best-known system for describing Diamond quality. However, what matters is not only each individual value, but how they work together.
Fancy Colors & Fancy Shapes
Diamond knowledge extends beyond colorless round brilliants. Fancy Color Lab Grown Diamonds and special shapes open up a much broader creative world.
Understanding Diamond colors Discovering shapes
Understanding the Diamond as a shape
Round, Oval, Pear, or Emerald describe the shape. Facets, proportions, and anatomy, on the other hand, determine how that shape is constructed and perceived.
Distinguishing documents correctly
Grading reports, laboratory reports, and product certificates serve different purposes. Understanding these differences makes it much easier to interpret information about a Diamond.
From knowledge to a purchasing decision
Not every Diamond needs to have maximum values in every category. What matters is the balance between visual impact, personal style, jewelry design, and budget.
Understanding the piece of jewelry as a whole
Even the finest Diamond only becomes a piece of jewelry through its setting and precious metal. Proper care and storage help preserve its beauty for years to come.
Knowledge gives you confidence when making your choice.
The ROSY Diamond Library combines technical fundamentals with practical buying advice. Read individual topics selectively or use the library step by step—from the formation of a Diamond to the finished piece of jewelry.
