A Private and Exclusive Approach to Custom Engagement Rings in Hawaii

Can’t imagine going to any other jeweler, let alone another jewelry company. With Moshe you get the one to one personable experience. Each engagement ring is created for you, nothing like those jewelry stores where I see at least 20+ girls with the same exact ring style!! Moshe is always on top of everything- excellent communication skills and customer service. Moshe created the most perfect ring. It was more than I could have ever imagine.

I can't express enough how absolutely wonderful Moshe is and the entire Diamond Guy Hawaii staff.

She couldn’t say no after seeing the ring! 
Hey also to @diamondguy808 for the most gorgeous ring of my DREAMS.
Moshe and his team are incredibly talented and made an absolutely stunning engagement ring.
Moshe did an amazing job making my fiancé's ring exactly as I had requested!
Moshe was incredibly responsive and professional. He worked with me to get the perfect jewelry at a fair price. He even was able to have it made expedited over the holidays..
This has been a long awaited review. When they say "it's worth the wait" it definitely is WORTH IT!!!! Till this day, I absolutely love love love my ring!..
  Hey Moshe, sorry it’s late but thank you so much for all the help, Mychal tried to get a good picture of the ring with the desert in the background. Mahalo dude!! – Christian K.
  Moshe, She said YESSSSS!!! Thank you again for such a beautiful ring. You a truly a master at your craft. Your ability to bring out the emotion of the diamond is second to none. She cannot stop looking at it. Million thanks bro!!!
Here are some pics of the ring and Haleakala summit. I thought it was going to be raining in Maui during the proposal but the weather was perfect. Amazing. . . . Thanks again Moshe for everything!!
Aloha, Thank you @diamondguy808 Moshe for the amazing ring. I arranged a beautiful New Years sunrise proposal and she said YES! She looks at her ring constantly saying “Is this really mine?” Awesome work and we’ll be back for the wedding bands! Thanks again!! Mahalo, – Nathan M. (Yelp ★★★★★)
Thank you @diamondguy808 for creating such a beautiful masterpiece. I had no idea that the ring I "liked" on your ig was a surprise for me. #witharinglikethishowcanisayno
I don't care if you live in Hawaii or not, stop what you are doing and send Diamond Guy an email if you are in market for a diamond engagement ring.
After traveling to Tahiti last year I brought home a pearl which my fiance had fallen in love with. Knowing she didn't want a traditional diamond engagement ring, Moshe was able to to take our concept and create a stunning pearl engagement ring which we both absolutely love.
I found Moshe via Yelp. The positive comments and photos motivated me to call for a consultation. I called for an appointment and was able to meet with Moshe soon after. I wanted to upgrade my wedding ring to a more modern setting. I talked to him about what I wanted and he showed me […]
It was all we had hoped for and more. I can promise you, you will not regret the decision to work with him! I can honestly say it was one of the best decisions we have ever made.
Once I saw the ring, my heart started racing so fast, I wanted to cry because IT WAS EVERYTHING I IMAGINED IT TO BE. I'm so grateful my bf trusted Moshe and chose him to create such an important thing to us.
Some jewelers may be knowledgeable, but I believe that few--VERY FEW--have the fine aesthetic sensibility and vision that Moshe also possesses.
My boyfriend came to Moshe. And from what he said he had a very awesome appointment! Very helpful & honest. He(my bf) picked out an engagement ring and I couldn’t have asked for a better ring! I’m in love with it! I can’t stop looking at it! Thank you for everything! – Chereen B. (Yelp […]
I can't thank Moshe enough for blessing me with my dream ring he is a sincere and honest jeweler not only have I found a new jeweler I found a friend thank you all the way from Cali !
I don't think I can ever buy Jewelry at retail store ever again. Moshe is a personalized, custom jeweler who provides excellent customer service with an inventory girls only dream of.
My fiancé Tiffany absolutely LOVES her ring and I now look like a hero . This is an ethical company who will give you the best product at the best price and I now have a diamond dealer I can trust! Thanks again broda!!!
He is someone who genuinely cares about his clients and what they want. The Diamond Guy is a must! Thanks again for everything Moshe, if it wasn't for you and your amazing work I don't know if she would've said yes!
My fiancé and I were looking for a contemporary, yet simple sapphire engagement ring... Moshe went above and way beyond our expectations! We are both extremely happy and would recommend that anyone looking for unique and fair-priced rings to come to the Diamond Guy Hawaii.
I can't express how grateful my fiancé and I are to have had the privilege of working with Moshe and his team. I'll never be going to anyone else for our jewelry needs. Diamond guy Hawaii is our lifetime jeweler.
If you are planning on proposing to your significant other, do yourself a favor and go to Moshe! Don't even bother shopping around at big chain dealerships.
My girl said yes and can't stop showing off the ring that I thought I could never afford. I would recommend Diamondguy808 to all my friends and family .. he also can create jewelery you may want like earrings , pendant, you ask and I am sure he will make it happen
He was in Hawaii, and I was not. Fed up with the bad luck I was having locally, I decided to reach out to Moshe... From his very first response, I fell in love with his passion about his work! ...I am so happy I contacted Moshe.
I sincerely wanted to thank you for your God given talent of being an honest, informative and exceptional jeweler...

Moshe was great to work with and it was extremely easy to hash out design details with him -- even from Boston. He has a lot of experience working with clients long-distance and made me feel very at ease.
I was able to get a bigger center stone and higher 4Cs quality than what HW would be able to offer. The picture of the ring speaks for itself. WHAT A SPARKLER!
Mr. Hakemolo is all about his customer from start to finish. But I say "finish" very loosely because there really is no finish, as he is now a friend and will continue to get my business for the rest of my life. This is what potential customers should come to expect from Diamond Guy.
If you're looking for high quality, stylish, personalized and classy diamond ring, don't look any further than The Diamond Guy.
It's truly heartwarming and makes me cry thinking about how helpful and generous Moshe was, we are extremely thankful, blessed and grateful. I have a BEAUTIFUL ring and have received numerous comments on it within just a couple of short days 🙂
I can tell that there was a lot of thought and time put into making it such an intricate and detailed piece! He really paid attention to my fiancé's request and made my dream possible!
Even coming back from New York, moshe is the better than all jewelers in the diamond district. He's an expert that is committed to making his customers happy!!! I'm amazed!
I got exactly what I asked for. The ring turned out great and on time. But what really mattered was she said yes!!!
When i first received the ring, I was speechless, the ring has earned the term "perfection". I got exactly what I wanted and then some! Expectation was beyond expected!
His skill, knowledge, and passion are true for the diamonds and jewelry in particular but also for his clients. I have felt so incredibly special to have this ring on my finger-of course because of the man I am engaged to but also because of the beauty of the ring!!
Living in Oregon, I communicated with Moshe directly through email and over the phone. He has a lot of overseas clients, which made me feel more comfortable working with him... He guaranteed that we would both be extremely satisfied with the final product...and he delivered!
Regardless of your budget he works with you to create beautiful pieces based on your vision. My engagement ring was something I immediately fell in love with!
People talk about going online or going to the mainland to get an engagement ring. Don't do it! You won't get the same type of service or the passion or the friendship you'll get when you work with Moshe the "Diamond Guy."..
Not only was Moshe able to fit me in and get the ring done in time for the trip it looks incredible and my fiancé loves it! It made an already amazing trip unforgettable!
