Visit Spexton Fine Jewelry to view our selection of GIA-graded diamonds. 



 Established in 1931, GIA is the world’s foremost authority on diamonds, colored stones, and pearls. A public benefit, nonprofit institute, GIA is the leading source of knowledge, standards, and education in gems and jewelry.

The GIA is the gold standard in diamond grading. They established the 4Cs: Color, Cut, Clarity and Carat. To this day, the GIA's 4Cs and International Diamond Grading System™ are  the worldwide standard for evaluating diamond quality.

We specialize in creating custom engagement rings and wedding bands that can incorporate the diamond you choose. We set all of the diamonds right here in our store on Cherry Street in Tulsa, Oklahoma.

Our diamond specialists, Andy Marcum and Steve Cluck, will search for the perfect diamond to fulfill your tastes and hit your budget goal. Graduate Diamond Expert Andy Marcum has over 40 years of experience buying and selling diamonds. He has traveled the world in connection with the jewelry business, including Bangkok, India, Israel, and Belgium. Steve Cluck has designed hundreds of engagement rings and custom pieces of jewelry, has six years of experience selling diamonds at our retail store, and is certified by the Gemological Institute of America (GIA) in Diamonds & Diamond Grading.

We specialize in high quality, GIA certified, excellent cut, conflict free diamonds of all shapes and carat weights. 

When you visit Spexton Fine Jewelry, we will login with you to our wholesale diamond trading network and show you the natural, GIA-certified diamonds that are currently for sale on the market. You can choose candidates you would like to see in person and we will bring them in for you to see within days.

We will help guide you through the process of buying a wonderful quality diamond for a low price.

Additionally, we also offer high quality, excellent cut, laboratory created diamonds in many shapes and carat weights. These laboratory created diamonds have all of the same chemical properties as natural diamonds. Therefore, they are real diamonds and possess the same qualities as natural diamonds.
