Simple, Symbiotic Relationships Equal Success

Jeremy Rothon Season 1 Episode 16

Coloured gemstones are can be incredibly complex to evaluate and understand. 

It’s with this in mind that Gübelin chose to launch their own gemstone grading system known as Gübelin Points. This rating service takes into account a stone’s beauty, rarity, and attractiveness and refers to the three domains as quality, rarity, and salience. They feel that this system provides a better orientation for collectors when they are looking for new pieces and helps to simplify the buying process. Until the end of 2021, this service will cost you CHF100 (R2,520.00) irrespective of species.

Certainly, buyers and sellers in this industry want to go about their business with the peace of mind that comes from knowing that their investments are the real deal. 

Considering the above, we’d like to share a few poorly kept secrets with you:

  • The Gem Lab has been rating coloured stones using the ICSL grading system for over 30 years. 
  • This system takes into account all the characteristics of the gemstone which directly relates to price, based on the final grade of the stone. 
  • This result is presented in percentages and plain English.
  • Once we have the final grade, the stone’s rarity is considered by the price guides. We have found that gemguide.com offers the most consistency with prices and takes into account rarity and origin.
  • Our fee structure takes the species into account otherwise the grading can outprice the gemstones worth.
