I enrolled in the GIA Graduate Colored Stones Diploma Program to help expand my family's retail business, which is currently limited to the big three gemstones - emerald, ruby and sapphire. Through this programme, I gained knowledge about so many more gemstones, their history, sources, quality factors, and more. I believe my knowledge will help me confidently communicate to my customers. I recommend this programme to anyone aspiring to be a part of the coloured gemstone industry.
