WHY BUYING CERTIFIED GEMSTONES IS IMPORTANT
The Gem Rock Auctions marketplace offers one of the largest and most comprehensive ranges of certified gemstones listed on the Internet. This gives our buyers more confidence and trust when purchasing a natural gemstone. If you are looking to buy a gemstone for the first time and don't know what the terms mean, it is best to start with certified gemstones. That way you will know that each stone has been tested by Gemmology Labs and is described 100% correctly.
Question 1: Why buy Certified Gems?
The market is flooded with glass, plastic and synthetic gemstones. Over the years this has done great harm to the gemstone industry. Gem Rock Auctions is dedicated to selling only natural gemstones to our customers. Having a large selection of certified and tested gemstones ads to the confidence of buyers.
Question 2: What labs are the most popular?
In the USA, the GIA is the most popular lab. However in other markets like Asia, labs such as GRS, Lotus Gemology, AIGS, IGI and AGL are popular choices.
Question 3: Can all reports be verified?
Most reports can be verified on the Gemstone labs website. However not all labs provide this service, so if that is important to you it is worth checking they offer that service before purchasing.
Question 4: Can every type of Gemstone be tested?
Yes! Diamond, Ruby, Sapphire and Emerald are the most common Gemstones to be tested, there is gemological data for every type of gemstone which means they can be tested and identified.
