    IF YOU DONT HAVE KNOWLEDGE WITH JEWELRIES, DO NOT GO HERE. OR ELSE YOU'll be fooled!! My husband supposed to buy a wedding ring, but since he dont know the difference about engagement ring and wedding ring, he bought instead an engagement ring from Diamonds by Siag. I went with my husband back to the shop to exchange the ring into wedding bands, and we told them we just want the same value and not more (760$) from what was initially paid. The Lady showed me wedding bands, and i told her what are the rings that same ranges with the price of what we paid, she answered back "i will tell you once you choose" I was down to my top 3 wedding bands and she said all of that are in the same range of 760$. When i finally choose the ring, surprisingly the amount is exactly 760$ while not even weighing it. In our minds, the one we choose was definitely lower value of the engagement ring. So i told them i will just choose the other ring that i was comparing. Suddenly, the lady said "its additional than 200$". I was so confused as not even 1 hour, you said that ring is same range of what we're looking for?? We decided to left since we have other plans and just decided to select the first wedding band i choose and not to argue. When my husband returned to pick up the ring, he asked the young man to weight the wedding band we choose and issue us a receipt. While doing the ring weight and quality proof check, the older man and the lady screamed at him and spoke to their language. (God knows if whatever description they put in our new receipt are the real!) They suddenly jump off to stop the young guy and defensively told my husband that the price of that wedding band is higher (showing tag price of thousand$), and they already gave a discount since I am with him... My husband proactively said that we felt the value of the wedding band was definitely lower than the engagement ring. They lady answered him that there's alot more diamonds in the wedding ring compared to the engagement ring so they already give a discount. My husband answered back, how come its more expensive if the weight of the wedding ring is lesser than the engagement ring? She didnt answer that question, but instead she showed another price tag that is more higher than the first one she showed and said that the real price and not the first one she showed? My husband didnt argue as he just left for a break and just let it slide. I personally went to other jewelers, showed them my wedding ring and the photo of the engagement ring, and they all said "we are cheated" ! Diamonds by Siag, we are not millionaires or billionaires. The money we are buying for a wedding ring is from hard work. Its unfair to be played by jewelers like you so you get more money. You're a jewelers, will you believe that this wedding ring is exactly same value of the engagement ring - 760$?

    We bought our wedding bands from Diamonds by Siag and had a great experience! Olivia is very kind & professional. She helped us pick out the perfect rings and had them made for us in a short time frame. Thanks again!

    Just got married on 7/31 and am absolutely in love with my new wedding band from Diamonds by Siag. They are so friendly here and I felt absolutely no pressure to purchase, which is saying a lot considering the vibes you get when you go into basically any other jeweler in the Diamond District. I went in with some inspiration photos for my band, and Tova was very knowledgeable and let me know that although the band is very pretty, she didn't recommend because the diamonds could easily fall out. She pointed me in the right direction to something similar that I wound up loving even more. Tova was very patient as I took a couple of weeks to decide. She even worked with me on the price. My sister and brother in law are regulars here and now me and my husband will be too!!!

    By far the best experience I ever had! Been to the Diamond district for several occasions but was never provided with such great customer service! Can't wait to wear my new ring!

    Look at this unique ring that Tova and Evelyn made for me

    When you are in need of a perfect gift for yourself or a love one this is where you should come ... Tova and Evelyn are the best I always come in with custom orders, they make it so beautiful that no one in this diamond district would do the work they do.. This is the one place I trust to buy all my jewelry, you have to feel comfortable in order to buy something Tova & Evelyn take their time to help you until you find what you need. Will definitely be coming back Thanks again guys, see you soon ;)

    I've never purchased an engagement ring before and after visiting several jewelry places I found myself at Diamonds By Siag where I was greeted by Olivia. Her & Evelyn were very helpful in the process of helping me find the perfect rings for my fiancé and myself. Also, helping find something within my budget but really worth. I love my ring, can't stop staring at it and I get compliments everyday. Definitely will be purchasing more jewelry with them in the future and recommend them to anyone I know!

    The caring team at Siag moved my favorite sapphire into the Victorian setting; now, the diamond has a more modern home, at left.

    Open on Saturday. Let's start there! While the Diamond District goes largely dark on Saturdays, Diamonds by Siag is open -- wide open -- and even has connections with a stone-setter from South Korea to make adjustments at a building down the street. Of course, most important is the value, the creativity, the access to great gems, and the price. All A++ at Siag. I went recently with a gorgeous, but old, Victorian setting. The setting has served as engagement ring and wedding band for years, holding a very valuable diamond. But I was tired of it. Mr. Siag (Al) and his lovely team of Tova, Evelyn and Olivia suggested I move the diamond to a lighter, more modern setting and use the Victorian piece to hold a sapphire. Easy. Convenient. Beautiful. And at a great price (I compared their plan with prices at two other jewelers, and Siag was 25-30 percent cheaper). The story doesn't end there. The sapphire I owned had two small baguettes in its earlier setting, and Siag's team suggested I use those baguettes as the centerpiece for my first pair of diamond earrings. Brilliant, literally! No matter what you're buying -- your first diamond or your tenth -- you will be well cared for here. All members of the team live by a tight code of ethics. They will never let you leave disappointed. And they're honest about what looks good, even when they sell a smaller piece. It doesn't get better than this place. If only the rest of New York worked the same way. (On the price range rating, not sure what meaning this has when one is spending hundreds or thousands on gems).

    My fiancé had been searching all around the diamond district for the perfect diamond and setting. He went with Siag because of their excellent customer service and honesty with the quality of diamonds. My diamond is gorgeous! I went back the same day to see other setting options, and have my ring sized smaller. I had mentioned to them that I was stressed, and they laughed and brought out a cold bottle of vodka! So perfect! I decided on keeping the original setting my fiancé had chosen, and was brought across the street to the man who does the adjustments. 5 stars for him as well- my ring was sized perfectly in 20 minutes, and he repaired a woven gold bracelet I had dented. I couldn't be happier with the entire experience, and I highly recommend Siag... I will catch my diamond sparkling and it reflects rainbows, so beautiful!

    my gorgeous ring!
    Michelle D.

    My boyfriend (no fiancé!!!) went to see rings/diamonds and were helped by Tova, who was extremely knowledgeable, honest and friendly. We immediately knew that we were in good hands. It was there and then that we chose the diamond that he would eventually come back and purchase for our engagement! He went back a few weeks later and was helped by 2 other ladies who work there, who were equally as professional. Yesterday he proposed and my ring is everything I could have hoped for and more - it is absolutely stunning! Turns out that my boyfriends' friend also ended up joining him to pick up my ring and purchased a gorgeous black diamond necklace, which he is very satisfied with. Diamonds by Siag will be our go to jeweler from now on! I would definitely recommend them for anyone looking for quality pieces from knowledgeable and honest people that truly have your best interest in mind. I love my ring!!!

    Great selection and service. Bought a diamond crossover ring. Got 2 independent appraisals and the ring checked out and appraised for quite a bit more than paid. Three weeks later I went back and they took my to get it sized as it was a little loose. Did it while I waited at no cost.

    I had to share my experience because I truly wish I had come here from the very beginning…read more Jangmi was actually the first place I went to when I started ring shopping. I wanted to see a variety of designs, shapes, and settings--and they had so many beautiful options to try on. The experience was warm, helpful, and not overwhelming at all. However, I ended up going with another jeweler a few stores down because my boyfriend had a connection there. The moment I received my ring, I immediately regretted not choosing Jangmi. The ring I got was nothing close to what I had asked for. The prongs were bent, and I had specifically requested a higher setting so that a wedding band could sit flush--but none of my bands (even very thin ones) sat properly. I brought it back and asked for multiple fixes. To his credit, he did make adjustments for free, but when I received the ring the second time, it still didn't match my vision at all. What I wanted was simple and classic: a 6-prong setting with tall, straight prongs (similar to the Tiffany style) and small claw tips. Instead, the ring was still not high enough, and the prongs were extremely thick--both from the top and side view--which completely took away from the beauty of the diamond. At that point, I was honestly so frustrated and ready to give up. But I remembered how positive my initial experience at Jangmi was, so I decided to reach out and ask if they could reset my ring. Even though the previous jeweler was willing to keep making changes for free, I didn't feel comfortable going back. I would much rather pay for something done right. And I am SO glad I did. Jangmi had the exact design I had been envisioning all along. Mrs. Kim was incredibly patient, attentive, and knowledgeable. She had a wax model made for me to try on before finalizing the ring, which made such a huge difference. Seeing and wearing the design in person gave me so much confidence--honestly, I preferred this so much more than just looking at CAD images, which can be hard to interpret if you're not in the industry. Within just two weeks, my ring was exactly what I had dreamed of from the start. The craftsmanship, the proportions, the setting--everything was perfect. My biggest regret is not coming to Jangmi Jewelry from the beginning. But one thing I can promise is that I will absolutely be coming back here for my wedding bands. If you're even thinking about going here--just do it. You won't regret it!

    I cannot recommend Jangmi enough! Mrs. Kim was incredible throughout the entire engagement ring…read moreprocess.

From the moment we walked in, he took so much time to walk us through every detail, answering all of our questions without ever making us feel rushed.

On top of that, he gave us an extremely fair price that honestly exceeded our expectations.

    With I could give them 10 stars!!!…read more I had an emergency situation where I needed diamonds set into a new setting plus needed it the same day! Asked around to all my contacts and did my Google and Yelp due diligence and I was referred to I. D. Jewelery without hesitation, even Google AI said go to them! First off it's a true family owned and operated business. And they treat you like family too (minus the drama) everyone was so warm and friendly. I first called and spoke to lovely Anna and she told me it was possible but to come in so their jeweler can take a look at it first. I got there around 11am and I told them my dilemma, Tammy and her team made me feel reassured all would work out and Yekutiel did not hesitate and got on the phone with his setter and told me to come back by 4:30. Mind. Freaking. Blown. They did a magnificent job of setting my diamonds into my new setting but they were also very impressed by the craftsmanship of my custom ring setting. Because it was an emergency situation, I was ready to pay over $1K for this service but the bill was not even close to that number. As the owner said, he is in the business of making people happy not price gauging his customers. The BEST in the jewelry business and I'm so looking forward to going back to get an actual custom piece made there very soon too!
