• Scarcity of gemstones coupled with its constant demand makes it very dear. Human endeavour to conquer / copy the nature and inherent importunateness to earn more have led to creation of fake, imitation and synthetics by simulating the natural ones. One is not sure what he is buying. There is lot of mix - up in the trade.

All gems, natural or synthetic, leave in them a trail of evidences for its exact identification. GTL finds out the truth by non-destructive scientific analysis.
