Tustin Diamond Exchange,#1 GIA Diamond Wholesalers & Engagement Rings

I been looking for the perfect engagement ring and I've checked many jewelry stores in the OC area and none of them had what i was looking for. I walked into this store and a sales lady named Samantha greeted me very polite and knowledgeable. I showed her a pic of a ring that I'm looking for and they had many styles to show me. Great selection and great service. I chose the stone in the quality that i was looking for and the size of my soon to be fiance & they put it together in about an hour. I definitely recommend that you check this place out. I am thrilled with their service. Thank you so much Samantha

BEWARE OF TUSTIN DIAMOND fraudulent "diamonds"! I purchased four pieces of jewelry, including an $8 thousand dollar pair of 2ct diamond earrings, from Tustin Diamond Exchange June 18, 2018 which totaled close to $17 thousand dollars. This was my first pair of real diamond earrings and I was excited. On March 12, 2022, I went to the Los Angeles diamond district with a friend while she met with her personal jeweler and while there I asked for my earrings to be looked at. The jeweler stated that my earrings are not the color or clarity I was told when I purchased them and that they are laser drilled which simply means a laser breaks up and fills in occlusions. This is not illegal, however, as supposedly reputable jewelers, the consumer is to be notified; Tustin Diamond Exchange sold me a fake bill of goods and I was not informed that the diamonds I was purchasing were laser drilled. When I contacted the owner, Anthony (who denies being the owner when it's convenient for him), and explained the situation on Saturday, March 12th, 2022, he told me that my friend's jeweler was a liar, even though she purchases $100 thousand plus annually from her jeweler, and Anthony angrily took great lengths (and hostility) to explain to me that Tustin Diamond Exchange doesn't sell laser drilled diamonds. I took the earrings to two other independent jewelers in the Los Angeles diamond district that day who told me the same thing about my diamonds being laser drilled. Additionally, I visited a Certified Gemologist in Laguna Niguel on March 15, 2022, who confirmed the laser drilling. I also asked Anthony at that time for a copy of the appraisal from Tustin Diamond Exchange to which he replied they don't keep records of appraisals and he would need to re-appraise the earrings. Oh yes, the "Certified Appraisal " which the Tustin Diamond Exchange provides the customer with at the time of purchase, is worthless. The only certified appraisals come from a certified gemologist and it's issued through the GIA (Gemological Institute of America); Tustin Diamond Exchange does not have a GIA certified gemologist on staff and therefore what they consider "certified " is falsehood. I told Anthony, who advised me to not sell my earrings to the jewelers in Los Angeles and to come into Tustin Diamond Exchange on Tuesday, March 15th at 11am and he would purchase the earrings for more than the $2500 I was being offered by the Los Angeles jeweler; I agreed to meet him. When I showed up at the Tustin Diamond Exchange on March 15, 2022 at 11am, the doors were locked and no one was there. I called Anthony, who had my phone number to reschedule if necessary - but didn't - and he stated he's sick and can't meet me. I requested another employee open the store and he stated there is no one else to open the store; he alsodenied that he's the owner of Tustin Diamond Exchange - he is. Additionally, when I demanded that he meet with me, he threatened to call the Tustin police for harassing him; I've called him three times in four days. Finally, he told me to sue him, he doesn't care. So I will. Further, their website states they are "Certified Professionals". I would warn future customers to request the certifying agency and to know that the "Certified Appraisal" given to you at the time of purchase from Tustin Diamond Exchange is worthless when it comes to reselling their jewelry and the value amount they assess is arbitrary. Beware of spending your hard earned money on fake jewelry as all that glitters doesn't equate to real diamonds.

My bf purchased engagement ring for me on 6.23.21- He gave me the ring- 7.17.21- it was the weekend so we took it back to have it sized the following week. After the sizing -I got the ring back a week later- and it was missing the following - side setting stones (thought it was due to sizing because i have very small ring size) and was not given the diamonds that were removed. Also, the authenticity stamp of 14K was removed. I wore the ring for a few weeks and lost a diamond on the claw holding the main stone in place- I took it back to them 9.10.21 to fix because high end jewellery should not be loosing ANY stones (this is due to poor craftsmanship). When I took the ring to be fixed- I told them the following was wrong with the ring: Main setting of the stone -was crooked and one of the prongs was not holding the main diamond in place, the stone on the claw fell off, the 14K stamp was missing and underneath the setting the gold was rough and hand bumps due to it not being finished or polished. Anthony assured me he will make it perfect and I would be happy. Fast forward to 9.23.21- after two weeks of them working on it- I went to pick it up yesterday and the ring was missing a stone some where else on the setting, the 3 diamonds left on the claws were removed and not given back to me and the main stone was still crooked and not set properly, and underneath was still unfinished. I told him this craftsman ship is terrible, I asked Anthony if this was going to be a problem with this setting, he lied and said no he told me he would try one more time to fix the setting and if not then he will order a new one because its a faulty setting and Anthony said "well the diamond is too small for this type of setting"- then why would you sell us something that is not correct to start with? After that I left and I spoke to my fiancé and I just didn't feel conformable with what is happening and I didn’t feel that I will be given a item I can wear. I called and spoke to Sunny over the phone and I told her I wanted to cut the back and forth and just get a different simpler setting that I am not going to have this problem with. She said ok come back in. Well my fiancé just didn’t feel that any of the craftsmanship (specially after reading other yelp issues of the same problem) would be good at this point so he asked for his money back- they said no they will not and I got a phone call today 9.24.21 to come pick up my ring its ready? This is not what I agreed to. I want a refund- we do not want anything from this TUSTIN DIAMOND EXCHANGE at this point- the customer service is terrible and they will not give us our money back. Its to the point where we want to return the wedding bands because we bought those in good faith to show we would be a continued client but after this experience we want nothing to do with the rings at this point. We just want our money back to go else where as they are saying we are threatening them when we just want things to be right. FIX IT Anthony- refund our money! You are a scammer and you still have the ring! GIVE US OUR MONEY BACK!  DO NOT GO TO THIS BUSINESS THEY ARE GOING TO RIP YOU OFF! I filed a complaint with the Better Business Bureau today!

I have been shopping for a 3 carat diamond ring and have been to la jewelry mart and all other jewelry stores all over, till i came to the Tustin Diamond Exchange. I got a very beautiful G.I.A certified diamond at a much lower price than all jewelers that claim to sell at wholesale price! They set and sized my ring in about one hour excellent workmanship. I can not be more happier with my purchase. If you looking for a great price and quality this is the place, so happy i drove up here.
