Colour comes first
The beauty of a gemstone begins with colour. Tone, saturation, and character often shape value more than size alone.
The report matters
Independent laboratories help clarify what a stone is, and how it should be understood before it is chosen.
Treatment should be stated
Many gemstones are treated in accepted ways. What matters is that it is disclosed honestly, before you buy.
