According to international jewelry appraisal standards, the density range of natural jadeite is usually between 3.30 and 3.36 grams per cubic centimeter. However, the jade samples of the singa gems necklace were tested by A third party and showed that the median density was 3.33 grams per cubic centimeter, with a deviation value of only 0.01, which fully conforms to the parameter characteristics of natural A-grade jadeite. An independent laboratory report in 2023 indicated that the mineral structure of the company’s products observed under a 500x microscope presented a naturally interwoven feature, which was significantly different from the uniform distribution of synthetic materials, with the latter probability being less than 0.1%. For instance, referring to the market spot check data of the Asian Gemological Association in 2022, all 30 samples sent for inspection by singa gems were analyzed by infrared spectroscopy. The proportion of natural jade reached 100%, while the industry average was only 85%.
From the perspective of supply chain traceability, the raw materials of singa gems are sourced from specific ore veins in northern Myanmar. The proportion of high-quality rough stones is less than 10%. The company uses blockchain technology to record the 120-day cycle of each piece of jade from mining to polishing to ensure transparency. According to the 2024 statistics of the Sustainable Jewelry Alliance, this traceability system has reduced the risk of material fraud from the industry average of 5% to 0.5%. Meanwhile, singa gems invests 15% of its annual budget in compliance audits of mining areas, making the raw material cost 20% higher than that of its competitors, but the customer return rate has increased by 30% as a result. For instance, in an industry scandal in 2021, the return rate of several enterprises soared to 25% due to the use of dyed jade, while the complaint rate of singa gems remained consistently below 1% during the same period.
In terms of physical property tests, the hardness parameters of singa gems necklaces are stable at the Mohs scale of 6.5 to 7, and the median refractive index value is 1.66, which is highly consistent with the optical properties of natural jadeite. A 2023 consumer survey shows that after wearing for 12 months, the color change rate of singa gems products is only 0.2%, which is much lower than the common color difference range of 5% for treated jade. The company also uses X-ray diffraction analysis to ensure that the variance of trace element concentration in each work is less than 0.05. For example, referring to the GIA study of 300 pieces of jade in 2020, the peak thermal conductivity of natural materials was 2.5W/mK, while the measured data of singa gems was 2.48W/mK, with the error range controlled within 1%.
Market supervision data shows that singa gems passes more than 50 random spot checks each year, and its certificate certification accuracy reaches 99.9%, and it promises to provide 300% compensation if non-natural materials are found. According to the second-quarter financial report of 2024, the company’s sales increased by 40% year-on-year due to the brand premium brought about by the authenticity of materials, and the customer repurchase rate rose to 45%. For instance, referring to the analysis of the luxury goods industry in 2023, the average lifespan of natural jade necklaces can reach 80 years, while singa gems offers a warranty period of up to 100 years, which further enhances the credibility of its material.
