Thalia AAA Curly Hawaiian Koa Tungsten Carbide Ring 4mm

Tungsten carbide is the most scratch resistant metal known to man and has the highest melting point of all metals at an astounding 6,191.6 degrees Fahrenheit. Tungsten is also hypoallergenic; people with allergies to gold or nickel can wear tungsten jewelry without worry of a reaction.

Tungsten keeps its finish forever and shines beautifully in the light. The AAA Curly Hawaiian Koa inlay appears almost 3-D like as it surrounds the ring completely. Our Thalia name and logo are laser engraved on the inside of the ring.

We offer this ring in two colors: Chrome which is essentially the raw tungsten carbide color and a 24K Gold Plated version.  

Does not include black ring gift box with foam and velvet insert shown.  But these are available seperately for $2.99

Gift Box Dimensions:
Width: 1.5"
Length: 1.5"
Height: 1.25"

Direct Light

Sometimes video is the only way to see the true magic of this wood.  Here it is in all of its glory.

Gold & Blue Abalone rings

After finding that the 2 rings we initially ordered and had delivered were incorrect sizes ( our fault) I sent them back and Thalia graciously accepted them and sent us the correct sizes free of any charge.
Thank you Thalia .

A ring so nice I bought it twice

Several weeks ago I bought two Blue Abalone Tungsten Carbide rings in gold for my wife and me. We were very impressed with the quality and beauty of the rings. My ring is an 8mm and my wife’s is a 4mm. Her ring was a bit larger than desired, and while Thalia will cheerfully exchange rings, I decided to buy a second 4mm ring a size smaller to match the first and together they are a striking pair.

Tougher than I thought.

I bought this ring because I needed a new wedding band. I liked it because it matches the inlay on my Martin guitar. I tried to order the right size but the ring that came was the wrong one and too big. Thalia promptly sent the right one and a size smaller. My wife liked it so much I ordered her one. I am rough on jewelry but it seems to be holding up very well.

A beautiful ring at a great price!

I bought two Blue Abalone Tungsten Carbide rings, an 8mm for me and a 4mm for my wife, and it was a purchase that I regard with delight and satisfaction whenever I see it on my finger. The beauty of the blue abalone set against the 24K gold plating is so eye-catching that I have received inquiries about it. The heft and density of the rings is very satisfying and belies the modest price. I previously purchased a Gibson Les Paul iPhone case from Thalia that is as beautiful as it is functional. (See my review here: https://www.thaliacapos.com/collections/phone-cases/products/hawaiian-koa-gibson-pearl-logo-lp-engraved-phone-case?variant=32640563478599 ). Thalia continues to supply magnificent products.

A Beautiful Ring

First, for the ring: It’s beautiful! Seems to be solid and very well made, although I still worry about banging and chipping the blue abalone, but so far it has held up very well. The fire in the color is outstanding, and is quite eye-catching. All in all, I’m very happy with this purchase. Second, for the service: I used the website’s ring sizer to order the ring, but when it arrived, it was clearly one size too large. I contacted Thalia and they promptly sent out a smaller replacement, along with a return-merchandise authorization mailing label. They didn’t ask for the orginal item to be returned first. Fantastic service!
