David at Ha Dynasty is very easy to work with, and made certain that through different tests, that our jade was authentic and gave us writtenappraisals on each. Very easy.We will return someday.Craig Ans Sue

I went to have two jade bangles verbally appraised. The owner was incredibly nice and friendly, had an immense knowledge of jade, and had very reasonable prices for both appraisals and jewelry. He tested my jadeite bangles with conductive and optical equipment. I ended up buying a two-tone pixiu jadeite ring (grade A), and love it! Looking forward to my next visit.

This amazing experience all started with a call to David. He was so kind and polite on the phone in setting up an appointment and giving us directions to his kiosk. We arrived almost and hour early and were still immediately helped by him. The process itself was thorough and professional. We were having a wedding ring appraised for insurance purposes. He specially asked to keep all available information hidden until he was done to prove his accuracy, which was spot on. I truly wish I had a regular need for jewelry appraisal, as this experience was truly enjoyable. Don’t go to any establishment charging $100+ for one item when David will take care of you for a bargain.

Top notch appraiser! Not only does David posses a wealth of knowledge concerning jade, he also does his appraisals for a fair price. I called around to several auction houses and insurance specialists to see if they could appraise my jade collection. Many offered to do so for rates in the hundreds per item, and they had rigid appointments. David offered to appraise whenever worked best with my schedule AND he did all my pieces for the same price the others were charging for one item! I was in over my head, but David was able to give me detailed information and a price range of what he believed each piece would bring. As I had so many pieces, he even came down to my car to appraise. Overall, I was amazed by the customer service and knowledge David presented. If you want to know exactly what you have and what its worth, I highly recommend going to David.

My wife and I visited David Ha today (12/4/18) to have him appraise carved jade jewelry inherited from my father. Our experience with David was outstanding, from the conversations on the phone to arrange the appointment, to our face-to-face meeting with him at his place of business. He was helpful, friendly, courteous, professional and kind. His fee was very reasonable, and his assessments of our pieces were thorough, complete and honest. We recommend David Ha without reservation, and we intend to do more business with him whenever the need arises.

AMAZING service. Very nice and helped explained everything very clearly and informative. Has a very unique and awesome collection of various jade carvings, diamonds, rings, gems, antiques, and bangles. I joined the one-on-one hands on tutorial with Mr.David, and it is just extraordinary. I learned a lot about how to look at different jades, semi-precious stones, and lab instruments. 5 star recommendation for appraisals, or looking for rare unique jade pieces. Has a lot of rare rings like ruby, diamonds, sapphire, aquamarine, etc. Truly amazing. Best place I have ever been to. I will definitely come back again.

We wanted to know how much my moms jewelry cost so I had them appraised here. We like how honest and professional they are here. Gave me clear details of the jewelry we had on our hands. They also have awesome collection of jade figurines! Would definitely come back here for their services.

Excellent customer service experience! I called David, owner of this establishment if I could come in to verify a diamond on my engagement ring if it matched the certification that it came with. David was very friendly and professional over the phone and in person. He is GIA certified and only uses top-of-the-line equipment in his gemstone evaluations. I highly recommend his services not only because of his outstanding service and credentials but because of his genuine integrity in his work.

Visited David for appraisal, hes awesome! I think I chewed his ear out with a million questions but he answered all very politely. Highly recommend!

I selected David Ha (the owner of Ha Dynasty Jewelry & Gems Laboratory) based upon my having previously read various positive write-ups from patrons who left feedback on Google and Yelp, including one write-up that was directly on point to the services that were needed on this particular occasion. I handle family law matters in the county of Los Angeles, and today was the court-ordered exchange for the ex-husband to return the 2 karat diamond wedding ring to the ex-wife. Given the history of this case, I wanted verification as to what was being returned. Counsel for the parties agreed that it was cheaper to pay Mr. Ha to travel to the location for the exchange (Diamond Bar), rather than for counsel to travel to Mr. Has store (San Gabriel). Since today was also the scheduled move-out of personal effects from the prior family residence, it made sense to do the diamond verification at the same time. I paid Mr. Ha in full a couple of days in advance for his services to ensure that he would feel good about traveling to Diamond Bar, and I was given a receipt of prepayment. Mr. Ha arrived today on time as promised. Mr. Ha examined the diamond certification that accompanied the ring, and used a variety of tools to examine the ring itself -- including, but not limited to two different types of diamond testing devices, a jewelers loupe with built-in lights, a jewelers micrometer, and documentation regarding diamonds. Mr. Ha explained the type of diamond certification that accompanied the ring versus other forms of diamond certification, and Mr. Ha wrote-up his own diamond certification with an appraised value. Although demanding a diamond verification from a qualified expert (as a condition of the exchange) caused some hard feelings on the part of the ex-husband, my job is to protect the rights of my clients. My client felt reassured and so did I. I look forward to visiting the store again to have a look at the merchandise under circumstances unrelated to my business, and I would definitely use Mr. Ha again in the future when the need arises. I would not hesitate to refer Mr. Ha to colleagues and friends, as Mr. Ha is a man of integrity who cares a great deal about the quality of his work and about his reputation in the community.

So knowledgeable, kind and trustworthy.

Rudest people ever and poor prices.
