Working with Rowan and Ray at Richardson’s Sapphire Mine has been an absolute pleasure. Their exceptional customer service, attention to detail, and unwavering commitment to meeting our needs as a supplier have made them invaluable to work with in our business.
One of the standout aspects of Richardson’s Sapphire Mine is the incredible variety of colours and types of sapphires they offer. From striking blues and vibrant greens to rare parti and yellow sapphires, their range is truly impressive and consistently of exceptional quality.
What also sets Rowan and Ray apart is their vast knowledge of sapphires, which they generously share. Whether dealing with customers or suppliers, they never hesitate to educate and guide with patience and passion—something we greatly appreciate and value in working with them.
We truly enjoy working with Rowan and Ray and look forward to continuing this relationship for many years to come. Their professionalism, integrity, and deep love for what they do make them a standout in the industry.
