Please indicate or inquire. Most ring and band styles are available in the full range of 3-33 mm. Please refer to the ring pages or to the order form for prices and the width availability for each ring style.

Important Information on titanium grades: All titanium rings, bands, and accessories offered here are quoted at their 'base' price when made of Commercial Pure Titanium, grade II (Ti 999), sporting the upwards of 40,000 psi in tensile strength. You may, however, order them manufactured from Titanium 6/4 (Aircraft Grade with the upwards of 150,000 psi in tensile strength) for an extra charge of $40.00, or in the mighty Titanium 6/6/2 (heavy-duty and aerospace grade with the upwards of 180,000psi in tensile pressure) for an extra charge of $115.00 from the base price. All are hypoallergenic. For further information on Ti grades go to "Titanium" on our menu. Here you will find interesting general and historical background information on Titanium and Titanium grades. Notice: Despite claims to the contrary by some manufacturers, presumably of limited access to the harder to find Ti-6/4 and Ti-6/6/2, those grades are undeniably, and metalurgically proven to be of substantially higher tensile strength and resistance, require longer machining, finishing and polishing, exert faster wear on tools and work accessories & materials, and are most definitely costlier. We will NOT, however, manufacture our tension settings in any weaker grade. In ordinary bands, the harder grades (Ti-6/4, Ti-6/6/2) will be less prone to dent, bend or otherwise damage; We do have, however, many satisfied customers who have purchased their non-tension rings and bands in Commercial Unalloyed Titanium.

Important Information on tension set titanium rings:
Traditionally, jewelers set precious stones in either a prong or bezel setting. Experimentation with hardening precious metals through 'work-hardening' (pressure or pounding) or special thermal treatments carried out by a few visionary individuals have enabled them in the past few decades to create new setting designs which allowed them to set precious stones in a new way. The sheer springiness with which the specially treated precious metals came to bear guaranteed a mighty, springy grip of a precious stone without the need to use bezels or prongs.
- A tension-set diamond is pressure held at its girdle within a gap created at the two pressing ends of a ring. The result is a stunning visual and aesthetic effect which exposes much of the diamond to the eye, and renders it to appear to almost hover in midair. Tension setting in titanium
- Titanium's metallurgically engineered intrinsic forces & springiness offers a solid grip, and enables a strong, solid tension setting. Titanium is the mounting itself, hence "tension-setting". Well, the tension is, indeed, mounting...
- Absolute Titanium's line of tension-set diamond rings offers you unique jewelry designs of breathtaking beauty and simplicity, each a jewelry marvel in itself, and is marked with its Titanium grade. Every ring is individually and meticulously crafted using the most advanced technologies, machinery and careful quality control. The result is that each of our titanium rings represents a feat of engineering, an accomplishment in design, and a victory for advanced metallurgy as applied in jewelry. Only aircraft and aerospace Titanium grades, of over 150,000 PSI in tensile strength and the most suitable "modulus of elasticity" (a term in metallurgy which indicates resistance to bending) are used by Absolute Titanium in these jewelry settings.
- Our tension settings are hand finished, and each diamond is set-to-order by hand and carefully tested. Release from the workshop and shipping always pend, first, on the sourcing and the completion of the diamond purchase, as well as, evidently, the actual setting job.
