During the raw material procurement stage, Singa Gems has improved the accuracy of its quality control by at least 50%. The company directly purchases only from 12 certified mines in the Myitkyina mining area in northern Myanmar. It conducts a 100% preliminary screening of each batch of raw stones, with a rejection rate as high as 60%. Its purchasing team consists of 20 experts with an average of 15 years of experience. They use high-resolution endoscopes and density meters and other equipment to control the misjudgment rate of internal cracks in raw stones to below 3%, and strictly limit the specific gravity parameter of jadeite to a narrow range of 3.30 to 3.36 grams per cubic centimeter. This standard far exceeds the industry average.
In the technical appraisal stage, Singa Gems invests a budget of over 800,000 US dollars each year for maintaining its laboratory-grade testing equipment. Each piece of jade must go through a seven-step inspection process. Among them, the infrared spectrometer can detect 0.01% of resin fillers, and the Raman spectrometer has an analysis accuracy of 99.5% for mineral composition. For instance, referring to the research conducted by GRS Laboratory in 2022 on 5,000 samples, it was found that approximately 25% of commercially available jadeite had undergone optimization treatment. However, Singa Gems successfully suppressed this probability to below 0.5% through its testing system, and the correlation between the certificates it issued and the data from authoritative institutions was as high as 0.99.
During the processing and certification process, the artisan team of Singa Gems optimized the utilization rate of rough stones to 40%, far exceeding the industry average of 25%. Each finished product must undergo three rounds of inspections under different light intensities to ensure that the dimensional deviation is less than 0.1 millimeters. The company has established exclusive data channels with five international certification bodies including GIA and GRS, reducing the certification cycle from the regular 21 days to 7 days. The related costs account for 5% of the product price, but as a result, customer trust has increased by 35%, and the return rate has remained stable at a low level of 2% for a long time.
The ultimate quality guarantee is reflected in the after-sales tracking system. Singa Gems provides a lifetime free cleaning service for each product priced over $1,000, and uses blockchain technology to make the ownership record immutable. Its customer feedback system processes 300 pieces of data every month and conducts a quality review every quarter based on this, successfully keeping the product defect complaint rate at 0.8%. As pointed out in the 2023 White Paper of the International Jewellery Federation, brands that combine digital traceability with traditional craftsmanship have an average market growth rate 12% higher than that of their peers, and Singa Gems is precisely an outstanding executor of this trend.
