Our company has been in business since the early 80's… prior to this our family had already established a great reputation for our remarkable prices and unbelievably fair business practices. At least one member of our immediate family has been in business since the 1950's and our name will carry on through future generations upholding our most important principles: 
Honesty, Integrity, Responsibility and last, but not least Low Prices.


Ivan Perlman, the president of S&I, began working in the business at the age of 18 years old where he quickly became a very knowledgeable diamond dealer under the tutelage of his father Max Perlman. Max was once famous for his creation of what is known as the laser drilling process of diamonds to help improve clarity as well as the diamond boiling method to use heat and pressure to help remove open flaws in diamonds. Ivan has built one of the best names in business with regards to his knowledge, fair dealings, credit history, and his very favorable payment terms. The company moves as Ivan moves as he presides and oversees over all aspects of its operations.

Elliott Davidson, Ivan's nephew and Max's grandson, has been in the company for the past 6 years and he has quickly become Ivan's right-hand man. Elliott's natural ability to learn and his very welcoming personality makes customers of all ideals feel right at home. He is helping to further market the company and expand into new territories and carry S&I's name into future generations.

When asked about the company by our customers, suppliers, peers, employees and other business partners, one thing is for sure: S&I will do whatever it takes to make sure what needs to be done gets done and gets done well.
