Getting to know a gemstone usually begins with color. We explore its shades, follow the play of light across its facets and imagine a future pendant or ring. A laboratory report adds information about the stone itself to that first impression.
In everyday language, this document is often called a certificate. A gemological laboratory prepares it based on the results of an examination.
What a Gemstone Report Can Tell You
The document identifies the material examined and records its characteristics, such as carat weight, dimensions, shape, cutting style and color. Laboratory examination can establish whether a stone is natural or laboratory-grown. The information included depends on the type of report selected.
These details complement photographs and video. Images reveal the character of a stone, while the document presents the findings of its examination. Together, they help you get to know a stone before purchasing it.
Laboratory Reports at VOC Gems
Most stones in our catalogue already have laboratory reports. If a new arrival is still awaiting examination, we arrange it before the sale. The standard laboratory report is included in the price of the stone.
Depending on the stone, we work with laboratories including GFCO, Bellerophon, GUILD and GRS.
If you would like an additional report from another laboratory with a presence in Bangkok, we can discuss this separately. Availability, cost and timing are agreed with you before the examination is commissioned.
The Report for Your Chosen Gemstone
If a particular stone has caught your eye, ask us for its laboratory report together with photographs and video. This lets you get to know it in more detail before purchasing: explore its color and cut, learn its dimensions and read the findings of its laboratory examination.
