Your One-Stop Jewelry Store in Kailua Kona, Hawaii

Kama'aina Diamond Company does it all from watch battery replacement, estate jewelry and gold buying, custom design jewelry, certified appraisals on any of your jewelry as well as jewelry cleaning and repairs.
 
We have gemstones from around the globe including rubies, emeralds, a rainbow selection of sapphire colors, opals (some from the now-depleted Lightning Ridge Mine in Australia), African tanzanite, amethyst, citrine, Tahitian and South Sea pearls. We offer diamonds in white as well as color (yellow, blue, black, champagne and cognac). Come in and visit us and see what we can do for you!
 
As an Exclusive Dealer for Gabrielle, Tycoon and Nenoir Diamonds, we're proud to be able to help you select that perfect shape, carat, clarity, color and cut you've been looking for. Whether a Gabrielle with 105 facets will suit your taste, the bold look of a Tycoon Cut or a Nenoir which has been tracked from its birthplace to your finger, we're confident that we can find the right diamond for you.
 
Our service goes beyond greeting you at the front door. When you buy anything from us, you become a part of our extended family. We'll follow up with you to make sure your diamonds are clean, sparkling and in good shape. We'll ask to inspect your jewelry once every six months or so when you have time to drop by and we will clean and check your diamonds to make sure they are secure. But most of all, we promise to provide you and your guests and loved ones who come in our door, with good, honest service and the care that you deserve. We want to be your 'local' jewelry store and we will go up and beyond what it takes to gain your business, your trust and your friendship.
 
​​Kama'aina Diamond Co. (KDC) has been in Kona since 1996 at the Kona Crossroads next to Safeway. Sandy Morton, started this business after being shocked at ​the prices jewelry stores were charging ​consumers for diamonds (and still ​are). So she opened her first store on the basis of bringing diamond prices ​down and being able to offer you, the consumer, beautiful diamonds at more attractive prices.
