I've been a longtime client of Kelly's, and I was so happy to find her again now that she's the owner of Diamond Nails. She has always provided amazing customer service--not just to me, but to my whole family. Kelly is incredibly consistent, detail-oriented, and truly cares about her clients. You never feel rushed, and she always makes sure you leave happy with your nails. It's rare to find someone you trust for years, and I'm so grateful she's back doing what she does best. If you're looking for someone who is talented, kind, and genuinely takes pride in her work, Kelly is your girl. Highly recommend! read more

I am SO happy that Kelly was able to take over this shop in Castro Valley! She has always been the best nail tech I've had, and she is also amazing at waxing eyebrows. Not to mention, she is the sweetest business owner you could ever meet. If you don't like something, she will help you until you are happy with the result. She goes out of her way to make you feel welcome every time. The rest of the team is very kind and professional, and the atmosphere just feels comfortable from the moment you walk in. The quality of work is great, and the services are reasonably priced. It's become my go-to nail place. Thank you for all that you do Kelly read more

So happy I found my girl Kelly! She's been doing my nails for over a decade. I love that she Is the sweetest person in the world, ultra talented and super meticulous.. I would give 10 stars if I could. read more

I really love this nail salon. All of the ladies are super friendly and they always get me in and out quickly. I would say it's probably my favorite nail salon in the East Bay area. Julia has done my nails the last few times and she always does a thorough and great job. They have a huge variety of colors to choose from. It's also always a relaxing and decompressing environment. The prices are also very fair. I've been to other salons in the area where they definitely up charge for every little thing. The only downside of this place is sometimes it's hard to find parking. But I always go very early in the morning so I never have an issue. I will definitely be coming back here!!! Julia is my go to girl and she's super friendly and great! read more

Diamond Nails - Cat eye nails! - Nail Salons Near Me - Castro Valley, California

I absolutely love this nail salon under new ownership!! Kelly is the best nail technician in the East Bay and her talent, creativity, and attention to detail are truly unmatched. If you've ever had your nails done by Kelly before, you already know -- she is an artist. I was beyond thrilled when she came back to town and opened her own place. Kelly has been an integral part of Castro Valley for so long -- not just as a business owner and amazing nail technician, but as someone who truly connects with her clients and community. It takes incredible courage and passion to start over -- and she has done it with so much grace and professionalism. Her new salon is beautiful, welcoming, and spotless. You can feel the positive energy the moment you walk in. She truly cares about her clients and takes her time to make sure every single person leaves happy. My appointments have been nothing short of amazing. Exceptional service, top-quality products, relaxing atmosphere, and nails that get compliments everywhere I go. Kelly's work speaks for itself. Her dedication, resilience, and talent shine through in every set she does. The East Bay is lucky to have her back, and this new chapter is well-deserved. If you want gorgeous nails done by someone who genuinely loves what she does, book with Kelly. You won't regret it. read more

Affordable and great service Kelly did my nails she was sweet and loved my nails ask for Kelly

Kelly found! When someone consistently does a beautiful job on your nails and toes, you follow them. When someone consistently (15 years) treats EVERYONE with kindness and respect, you follow them, Nail shops are bought and sold all the time. What isn't nice is putting false reviews on yelp to hurt someone who is trying to make a living just like you. Shame on you. read more

I used to go to diamond nails for a long time, but was disappointed in the quality of their work And now I definitely will not go back because as a business owner, the number one rule is, if you ever sell your business, you do not open or work at a business nearby And the new person that has taken over diamond nails did just that that's very unprofessional. You don't sell your business and take your clients with you somewhere else and hurt the person you sold it to read more

Got recommended to Kelly by my mother in law *Kimberly* who's been going to Kelly for the past TEN years and man have I been missing out on cute sets. Kelly has amazing customer service & makes sure she goes above and beyond for designs my baby shower is tomorrow not sure what I really wanted for my lion king theme and she absolutely killed it with my set! She for sure gained a new loyal customer so blessed to have had the opportunity to meet her today read more

Diamond Nails - Thank you Kelly! - Nail Salons Near Me - Castro Valley, California

An looong overdue review! My go to person is Lisa! Ever since I moved to Castro Valley a few years back, I've been trying to look for a nail salon that has ample parking and great customer service. I've been going to Lisa ever since and have always had a good experience. My nails always last so long!! I started at this nail salon prior to their remodeling, and now it looks even better and more modern. Definitely recommend read more

Speak up all you want... most of those women want you in and out. I've had 3 different women do my hands and toes and it's all the same. If your nails take longer than they want or if you give a critique/need them to fix something, it won't happen without an unnecessarily rude comment. They think they know what is best and right and will dismiss your wants and concerns. They won't care if you leave unhappy. Except Wendy. Book with Wendy. read more

Diamond Nails is under new ownership. I have been going there for 20yrs. The previous owner always took care of me like family. I wasn't sure what to expect. The new owner Kelly did my nails this week. She did a great job and made me feel comfortable and special. I wish her and the staff success. Linda always greeted everyone when coming in by name. I was always surprised that she not only knew her clients by name but knew everyone else's clients by name too. It will take awhile but my suggestion woukd be to carry the long standing tradition. Best of luck and again thankyou for an awesome experience. read more

Been going to Lisa for many years she very sweet and takes great care of my nails. The other girls here are also very nice I had my mani and pedi done multiple times and they've always lasted me 4-5 weeks. If I ever chip a nail I can always go there and they will fix it for me. For the rest of the reviews based off the new owner changing locations and taking her clients with her thats not a legit reason to leave a hard working store a 1 star review. It's embarrassing to have your customers from another nail salon leave a bad review because she sold her business and bought a new one. Please do better people. read more

I have been going to Diamond Nails in Castro Valley for several years, and have never had a bad experience. The salon has recently changed ownership and the new owner, Kelly, has been nothing but kind and caring, and is a pleasure to work with. She cares about her customer's satisfaction, and it shows. I have had the same technician, Wendy, since I started going there, and she is amazing. Everyone who works there is welcoming and accommodating. Customers come in smiling, and leave smiling. read more

The quality of the nails are so good. They are very on point with their designs. They are very kind and easy to talk to. You want your nails to be diamonds yall need to come here. read more

Really nice salon. They actually respect appointment times, since I have a busy schedule so this is very important to me. I usually get builder gel, which they do. Kelly did a great job of recreating my inspo for my choice of nail art. The shop is clean and relaxing. Overall 10/10 would go again. read more

Diamond Nails - Just had these done yesterday. - Nail Salons Near Me - Castro Valley, California

Wonderful service. Great nails and pedicures. Please disregard a review in the last few months related to the new owner as it does not tell the full story. She is a wonderful human who has maintained integrity in the transition process to a new shop. As a former client I was never contacted by her when she purchased her new shop. I was seeking a new place to get my nails done, as she had left the state, and "lo and behold" there she was after having moved back to the area. If you are looking for a nail salon, recommend coming by and deciding for yourself if this is the place for you. read more

I absolutely love Kelly at Diamond Nails! The shop is very pretty and relaxing environment. Highly recommend.

Diamond Nails has been my nail salon for about the last year or two. It was recommended by a friend and I have no complaints. This is definitely a place to make an appointment at! It gets busy and it's nice to be able to just walk in. The place is located right off the boulevard. They have a small parking lot but usually you can snag a spot in there. I like how nice and modern it is inside. It's really spacious inside and everything looks super sleek. Very relaxing vibes. They have TVs that are muted and usually are playing a cooking program (which I like-- it's usually an interesting show). The ladies are all very nice and do a great job on your nails. They will check in to see if you like how your nails are coming along and ask about your day. They have a lot of colors to choose from and the pedicure chairs that give a massage. I typically get a gel manicure and pedicure. They usually work on them at the same time which makes the trip a little quicker. However, I never feel like they rush through the services. They take their time to provide quality. I have never left here disappointed. I've never been cut or had an unpleasant experience. Remember to bring cash for the tip! read more

All the staff is super friendly! Their pedicures are amazing and will only get my fills done there!!! Love them!!

Diamond Nails just got a new regular! Kelly (the new owner) went out of her way to fit me into her busy schedule! Even living almost an hour away in San Jose, Diamond Nails is my new regular and no other salon has been able to beat the quality, service, and price! Kelly was so sweet and patient with my indecisiveness and explains every single detail to me. My nails came out even better than I expected because of her suggestions! I loved getting my nails done in such a clean and beautiful place from such experienced and kind ladies! read more

I came here for my manicure and it was a great experience. Kelly did my nails so efficiently and is super nice and gentle. Everyone there is so welcoming and friendly. I definitely recommend! read more

I have gone here a few times and have never walked out satisfied with my services. It's even more disappointing to know that the new owner Kelly sold her previous salon down the street and took all the clients to Diamond. It's truly unprofessional, of bad taste and shows bad character. Makes me not want to go here again! read more

This nail salon is a hidden gem. I have been here twice and both times I have had great experiences. The pedicure was amazing. The place is clean and filled with nice people. read more

I have been going to Diamond Nails for years! I see Wendy every two weeks for a pedicure and my nails. She is amazing! She's fun to talk to, her foot and lower leg massage is incredible, and she is so detailed in her work. My nails are always beautiful and I feel fantastic when I leave. Everyone in the shop is kind and friendly. All the customers (men too!) always look satisfied when they leave. The shop is beautiful and clean. I highly recommend Diamond Nails. It's a Castro Valley gem! read more

I highly recommend Diamond Nails in Castro Valley. I have been going there for 14 years! Very professional and clean. Wendy and Lisa are amazing:) New Owners are friendly and helpful. read more

I have been coming here for a couple years now. Usually I have a good experience, but this time it was absolutely terrible. Wendy does a good job, she did a great job with my mom's nails and the lady that did my grandma's nails was also good. The lady that did my full set did an absolute terrible job. Did not put enough coats - I can still see through my nails. She cut my pinky nail too deep, it really stings. She did not give me the nail shape I asked for. She kept making excuses for doing a bad job on my nails too. She's constantly talking & not even focused on the nails, she wears glasses, but can't even see the nails she's working on. My nails look shape looks slanted now. I used to recommend Diamond Nails, but I don't think I'll be doing that from now on. Please save your money and go somewhere else. read more

I really like this salon. They don't add additional charges that should already be included with manicures, unlike how some other salons do. The shop is clean, which is really important to me. Kelly did a great job on my nails and I would honestly book an appointment with her again. read more

Accommodating . I was in a hurry and they did a great job under pressures! So happy it worked for me!
