This commitment allows customers to purchase with confidence, knowing their diamonds support legitimate economic development in mining communities.
Appraisals
We provide insurance-compliant appraisals with detailed descriptions and photos, completed within 1 business day to a week. Our realistic valuations balance replacement costs with reasonable premiums. Customers can wait for completion but should expect several hours due to concurrent customer service demands.
Watch Services
We install watch batteries and adjust metal/leather bands while you wait. Our service includes gasket oiling and time setting. While we don't repair broken watch mechanisms, our competitive pricing and quick turnaround for battery replacements make us a preferred local service provider for timepiece maintenance.
Scrap Gold Buying
We purchase scrap gold jewelry (8kt-24kt) and dental gold at current market prices. Our transparent process separates metals by karat and provides immediate valuation. We don't buy coins or ingots but offer competitive rates for natural nuggets and used jewelry, with payments made in cash or store credit.

I brought in my engagement ring (purchased elsewhere) because I thought it needed to be resized and the prongs tightenedmy center stone felt a little loose. The wonderful ladies working there took the time to explain why my ring actually felt too big, and it turned out I didnt need a resize after all! They offered an alternative adjustment I didnt even know was possible, suggested more cost-effective options, and even tightened my prongs at no extra charge.

My ring was ready within just a couple of business days and looked absolutely gorgeous when I picked it up. The staff was so warm, friendly, and genuinely made me feel comfortable and cared for. Ill definitely be coming back to them for all my future jewelry needswedding bands, gifts, repairs, and more. Highly recommend!

AMAZING STORE AND SERVICE!!! I went to borthwick jewelry to buy a lab grown diamond ring and I am beyond thrilled with both my ring and the amazing experience I had at the store. I got a beautiful diamond at an extremely fair price and couldnt be happier. All the staff including the owner, the diamond king, were so awesome and friendly. The whole experience felt very welcoming and fun rather than just being transactional. They also cleaned a bunch of my jewelry for free! They also had a great selection of really impressive crystals and large geodes.

Went to see the diamond king today after many years of hearing his advertisements. Popped in with my wife to see about having a ring appraised or potentially selling it. The king was blinged out, fun, light hearted and offered us half a dozen options to maximize our money, none of which included him Then he took a look at the diamonds, cleaned them and told us the best way to sell them to maximize our money.

He wrote down the specifics of the diamonds and offered advice on what to write in the advertisement. We're not really jewelry people but he had some handmade pieces from Mexico we vibed with so I'm going back to grab these earrings for my wife because I was so impressed with our experience and the earrings are awesome. His energy was great, everyone working was warm and fun. I asked if we can just come hang out at the shop sometime.

It's hard to believe anyone has anything negative to say about the guy because he's loosely goosey and it was easy peasy being in his store. If you don't like to deal with someone with some flavor, go to the mall. Imma bend the knee to the king.

We are extremely pleased with the service we received. We had two rings appraised for insurance purposes. The work was thorough, affordable and the turn around excellent. The people were friendly and knowledgeable. The shop is easy to get to and there is ample free parking. We will definitely go back should the need arise. I highly recommend Bothwick.

We went to Borthwick to get my wife's wedding ring fixed. They did an incredible job, also resizing the ring and making it shine once more, beautifully. The entire crew was welcoming and upbeat, the ring was ready in just a few days, and we will visit again. Thank you!
