GIA receives a varied and complex range of items for identification; everything from colored stones and pearls, unusual carvings and jewelry, to the latest in synthetics, and simulants, as well as treated gems. A significant area of activity involves the origin of color in gemstones, most notably, but far from limited to, diamonds, rubies, and sapphires.
Inspection, Care, and Handling Procedures GIA applies the same item identification and tracking procedures to gem identification as it does to diamond grading. Each item is assigned a bar-coded label with a unique internal identification number that is used to track it throughout the process. And at every step, special inspection, care, and handling procedures serve to protect a gem’s identity and ensure it is managed with the utmost care.
Weights and Measures. This is the first stop for any gemstone. Loose gems are weighed with an electronic micro-balance that captures the weight to the fifth decimal place. Loose polished stones are also measured with an optical measuring device to determine their proportions, measurements and facet angles. Mounted stones are measured, but not weighed.
Identification Items are then transferred to the Identification Inventory Control department for distribution to trained and experienced gemologists for servicing. Once an item is received by an initial gemologist, its recorded weight and measurements are verified, or if the item is mounted or strung, the gemologist will use manual measuring devices to determine and record necessary measurements.
Employing state-of-the-art technology in his research and identification efforts, the gemologist then performs a variety of analytical investigations, including a microscopic examination of the item, and performs all the tests required to properly determine its gemological identity and detect any treatments.
After that, the item is transferred to a second gemologist, who independently performs all necessary observations and testing. Depending on the identity and nature of the item, it may be examined by additional gemologists and research specialists.
Report Processing and Item Return Reports are generated after all results are finalized and services have been completed. All GIA Reports are examined and proofread to ensure quality before being sent to the client.
Last, the item is placed in its original container, joined with its report, and goes through final inspection and testing to ensure that the same submitted item is returned to the client.
Items are returned either in person through the Client Services department, or via courier through the Transport Services department. All information recorded for an item remains stored in the GIA Laboratory’s permanent database for future reference.

I can't express enough gratitude for the exceptional service I have gotten at Sea Wave. I went to them for my fiance's engagement ring and came back for her wedding band. Never before have I dealt with such a professional and helpful staff, with incredible industry expertise, who put such a priority on customer service. They have the best stones, are willing to work with you on any budget, and will do everything in their power to make sure the job is done right, even if it is a custom ring with the most intricate designs. The biggest difference is that the staff at Sea Wave puts such a focus on you, and helping you find the perfect piece of jewelry, that they don't have to "sell" you anything. The service and the quality of their craftsmanship speaks for itself. We won't shop for jewelry anywhere else! Thank you Mike for your exceptional work!

Strong recommend!! I come from Australia and have conference in NYC. I only have 1 day to shop and Mike give me a excellent experience. I also compare the other good reputation stores, but Sea Wave is the best. Honesty, patient ,good quality and they will tell you each diamond's feature why they are different price and let you choose. I end up with 2ct round diamond. Who said the only thing you shouldn't do in NY is buying diamond for the diamond district. I said the only thing you must do is buy diamond from sea wave. It sounds like advertisement but this is the way I want to thank mike he did a wonderful job and I really appreciated. I definitely will buy my next diamond from sea wave.
Exceeded expectations. After getting engaged and needing to purchase a new setting due to size issues my fiancé and I walked into sea wave randomly on a sat morning while browsing in the diamond district. It was still early and seawave was one of only a handful of stores open. And I'm so thankful they were because I found exactly what I was looking for. From the second we walked in we felt comfortable. These guys are not pushy jewelry salesman AT ALL. Their number one prioirity was helping me find the perfect setting for ME. Alex was our guy and was extremely knowledgeable. Upon looking at my center stone he immediately knew the exact color, cut, carat weight and clarity. After patiently looking at photos on my ipad of the type of setting I was looking for he presented me with many options before I found the one I'd been looking for. He agreed to buy back my original setting for a fair price and promised my new one would be ready in 2-3 weeks, which it was. He then had us watch while m...
Great service. Great price.. We just purchased our wedding bands and we had yet another great experience shopping at Sea Wave. After purchasing our engagement ring, we knew we would be back. The staff is extremely helpful and we both got the bands of our choice at a great deal. Thanks again!!
About this place. From the beginning the two men behind the counter, Mike and Alex, were able to clearly show and explain the differences between good and bad diamonds, provide a diamond which met my specifications, and create the ring within a short time frame. There was never any pressure to buy, and I was able to ask questions and make decisions at my own pace (no rush tactics that are so commonly used elsewhere in the diamond district). If you are in the market for a diamond make sure to stop by.
Alex was very helpful and honorable. Many of the guys on this street are dishonest, but Alex told me everything right upfront, both about buying my watch and selling me a different one. He also gave my friend a good deal on silver coins he was selling. I will go back again
Bought an engagement ring from Mike at Sea Wave Diamonds. I was extremely satisfied with the process and overall service. The team at Sea Wave really understood what I wanted at were able to cater to those priorities very well. I never felt pressured during the process and feel extremely positive and satisfied with my choice. My fiancé is extremely happy!
Before visiting NY I had checked out a few Diamond District stores on-line, and I was most impressed with SeaWave Diamonds. So on my 1st day in the city I headed to their store and saw for myself, their professionalism and personal attention to customer satisfaction. With their help I chose my diamond (which was a birthday present) and decribed the type of setting I wished. Just 3 days later I picked up the most beautiful ring I could have imagined. They took my loosely based idea and turned it into a very special ring and something totally unique. A few days later I returned and bought another ring from them as I was so reassured by the service I had received. Upon returning to my home I had the diamond ring valued for Insurance purposes and found it worth favorably higher than I had paid. So all in all a very pleasurable experience. But none of this would have been possible without the experience, knowledge, guidance and courtesy of these guys. So a big Thank You to all at SeaWave Di...
Sea Wave Diamonds is the BEST! My husband and I took a lot of time in search of a jeweler that we wanted to make "our jeweler." And let me tell you, after about 6 months of research, we finally found them. It's Sea Wave Diamonds. We usually work with Mike, who is amazing. He's super knowledgable, honest and works with us to give us the best. In the past 4 months, we've ordered several different pieces from them, including our wedding bands (simple white gold engraved band for hubby and an eternity band with diamonds for me), my bridesmaids gifts (sapphire studs), my 30th bday gift (sapphire earrings w/ diamonds around each sapphire) as well as got my engagement ring (family heirloom) reset and vintage pearl necklace restrung. And they did an outstanding job on everything. They really do spend the time and put in the effort to make exceptional pieces. So happy we found them. Thanks Sea Wave! Until next time (hopefully soon).
We were recommended Sea Wave by friends who had bought rings there before. Mike and his team are great at listening to you and showing different types of rings. So very professional and they did everything they could to please us and find the perfect ring. I love my ring!!I had an accident where one of the diamonds fell off, but there were no problems or fuss getting it fixed. Quick and good service! I was so pleased with Sea Wave Diamonds so my mom had her diamond ring specially made to fit another ring. She gets compliments of how beautiful is and she is very happy!Great place to get beautiful rings!!
My fiancé and I just returned yesterday to see Alex for our wedding bands because we received such great service from him during the purchase of my engagement ring. If you're in the market for any jewelry or time pieces you must see Alex. He's knowledgable, professional, and honest. You'll get a high quality piece for a fair price.
My soon to be husband and I have bought a total of 5 pieces from Sea Wave over the past year. We first purchased my engagement ring, which was no easy feat. Searching for a marquise without a bow tie and with well proportioned facets and lots of luster is both rare and costly. We spent a lot of time scouring the diamond district and Sea Wave had by far the best stones. To add to that, their metal work is also the best that I've seen on 47th street. We've also purchased our wedding bands, diamond earrings, and had a diamond necklace made from old family stones. Both the necklace and his wedding band were designed from scratch by Mike. I had an idea in my head for his wedding band, but nothing in print. Mike made it happen. This place rocks
My husband and I went to Sea Wave to make my engagement ring and both of our wedding rings. All of them came our beautifully. When I went to get the engagement ring appraised, the appraiser was very impressed and said he didn't see that quality of pave very often. The whole staff is friendly and easy to work with and all three of our rings were done on time. We're very happy we found a reliable jeweler in New York and would highly recommend them for purchases large and small!
