Working with K.Rosengart was a wonderful experience. They listened to me carefully and made a beautiful custom diamond band to fit perfectly with my engagement ring. I am thrilled with the way it turned out! I highly recommend K.Rosengart for all of your custom jewelry needs.

K Rosengart has phenomenal, ideal-cut diamond melee that they sell both to the trade AND to hobbyists and consumers without onerous minimum order requirements. The melee I have gotten from K Rosengart has been top quality and better priced than what I could get even from manufacturers in China.

I have had a decades long relationship with Karen from K. Rosengart. From the engagement ring she created over 31 years ago to new diamond wedding bands there is no other person I trust to take care of my wife and I when it comes to diamonds. The combination of trust, creativity and communication is unmatched!!!

I had an excellent experience purchasing melee diamonds from K Rosengart. I was building my own engagement ring for my (now) fiance, and Karen was very helpful. Great communication by phone, email, and actually the online chat as well. Most retailers I talked to only wanted to deal with customers associated with the jewelry trade, so I am grateful K.Rosengart was happy to deal with smaller customers like me!The 10 melee diamonds were excellent as far as I could tell. All had great diameter and color consistency. Prices were good. Overnight shipping arrived on time.

I met Karen at a conference last month and really appreciated how approachable she was to chat with. I told her one of my biggest issues with ordering melee in bulk was how inconsistent the parcels were. I work in CAD so I need my melee consistent with size and quality. She told me that was one aspect that set her apart form other vendors. I gave her a shot and have been extremely pleased with what she has been sending me. Her price is competitive, but the attention to detail surpasses other companies I've been ordering from. What will really keep me coming back is the warm personalities of her and her staff; she is a pleasure to work with.

My experience with Karen was exceptional!!!! This was my first time sending a diamond to be repaired. I called alot of people and asked alot of questions before settling on Karen to fix my diamond. There is a lot of trust that needs to be present to send your diamond to a business out of state. Not only with shipping, but with the person you send it to. She answered my million questions cheerfully and with exacting answers. After speaking with her I knew where my diamond would be and what would be done with it from start to finish. To my surprise, it was done before expected and back in my hands in under a week. The diamond was 100% again and they did it without affecting the size very much. I trust her to care for future diamond projects I will be working on in the near future. She is very trustworthy and the work is AMAZING!!!! Thanks again Karen!

Investing in Bitcoin was the best decision i made and I have been gaining a lot of profit with the aid of Mrs Eliana Russel who was introduced to me by my friend Reece, I have been making my profit and making my withdrawal easily. Her company's brokerage site is top notch and I am very impressed with the management and my trading process went smoothly. It wouldn't have been possible without her

From the start to finish the process went smoothly and effortlessly. perfect work she did i really enjoyed the process because of the hard work of the team.

Are you looking for a genuine, trustworthy trader/motorship in Crypto, NFT and Binary options,
then Mr. Ethan Payne is the right one for you. I was looking for the best not until I read good
reviews and recommendation about him. With his Great skill of Trading and Mining, he was able to make good
profit of my first $1000 investment. I was amazed how he turned a $1000 investment into $5000 just within a week.
At first i thought this was impossible until i give it a ty myself. I earned a very good profit and made my
withdrawal successfully directly to my bank account with no hidden charges. If you wish to invest,
kindly Contact her with the below details.
