2. Is it waterproof? Can I wear it every day?
Certainly!Our jewelry is built to last. Gemstones are precious because of their durability, scratch resistance, and brilliance.Yes, our pieces can safely come into contact with water. Most of our gemstones are rubies and sapphires (hardness of 9 on the Mohs scale)—so hard that even a metal knife(hardness of 4-6 on the Mohs scale) can’t scratch them!We hope their unyielding strength inspires you to face life’s challenges with confidence.

We are dedicated to fulfilling the dream of sparkling jewelry for every customer who values emotional worth. We will never compromise on quality or conscience. Your smile is our greatest motivation.
6. Why do your prices fluctuate?
Raw Material Costs - Price fluctuations of rare elements required for lab-grown gemstones
Craftsmanship Costs - Seasonal variations in labor costs for master artisans during peak periods
Production Capacity - The yield of raw materials also affects pricing
7. How long does it take to lab-grow a gemstone once?
In fact, for most of the gemstone varieties we cultivate, we have to wait for almost a year! The crystals grow slowly on the seeds, maintaining their natural crystal shape. At the end of this process, you get crystals that are identical to the rough stones found in nature, including their physical, chemical, and optical properties. Every time we open a crucible that hasn't been touched for ten months, we are filled with amazement. Sometimes, though, it also leaves us greatly disappointed. We are constantly experimenting, making subtle changes to improve the quality of the crystals. Continuous experimentation is key to sustained innovation. What's more, many of the lab-grown gemstones are unusable—on average, we lose 80-90% of the gemstones simply because of inclusions that are revealed during cutting. This is a natural part of the crystal growth process. We also have to sacrifice some crystals to use as seeds for the next round of growth.
8. How to choose the right size?
You can browse our ring size guide page. If you have any further questions, please feel free to contact us.
9. Do you include a certificate in your package?
All of our gemstones can be tested by GUILD. However, due to the long testing time and the high costs charged by authoritative laboratories, this would significantly increase the purchase cost for our customers. Therefore, Jewel Island adopts a sampling testing method: one piece from each batch is selected for testing. Since all gemstones of the same type are grown using the same process, the test result of the sample is sufficient to guarantee the authenticity of the entire batch.
We do not issue a certificate for every single piece. Of course, if you require a certificate, we can arrange testing for you, with costs ranging from 80to500 and a testing period of about one month. Please feel free to contact our customer service team for more information.
