Lab Fares


The Spanish Gemological Institute (IGE, Instituto Gemológico Español) is a non-profit association founded in 1967 with the aim to study, teach and promote gemology in Spain. IGE Gem Testing Laboratory was founded in 1969 and currently it is the most prestigious lab for gemstones testing in Spain. Equipped with advanced analytical techniques and highly qualified staff, it offers gemstones analysis and certification services to clients in Spain and abroad on a regular basis.

We are always happy to work with new clients and ready to help you to understand better our services and fares!

Lab fees

For all our laboratory services there are three different prices, that depends on the type of client:

General (highest price). For clients not related to IGE in any way.

Socios – Associates (medium price). For standard associates to IGE. To become an IGE associate you have to pay 70€/year and you get discounts in courses and Lab services, and also some other advantages from IGE.

Socios Profesionales – Professional Associates (lowest price). This special category of Associates pays 500 eur/year and has additional discounts on Lab services and courses. Additionally, they have the possibility to place their banner on the IGE website. This is the most interesting option if you intend submitting lots of stones for certification.

The prices do not include VAT (21%), not applicable to non-EU clients and EU firms with intra-Community VAT number.

Security seals

Gemstones with this simple report are returned in plastic bags with security seal band, at no additional charge. But if you prefer other security seals, if the size of the stone allows to use them, you can ask for the “LUX” plastic card blister. They have additional cost: 15 €.

How to ship stones to our Lab

Our clients use different courier services for shipment of stones to our Lab. Once the work is finished, the client orders the courier service for shipment of the stones back to him. There are many reliable international couriers that allow fast and secure shipment, that also can be assured according to clients preferences. For more details on shipment please contact us.


All the gemstones and jewels submitted to our Lab must be insured for the time the goods stay in our Lab. The insurance value is established by the client, being the minimum value for colored gemstones 600€ and for diamonds 3000€. The client pays 0.2% of the insured value, that is 1.20€ minimum for colored gemstones and 6€ for diamonds. This payment will be included to the invoice together with the payment for our Lab services.
