Your original band transformed into a Ringlock.

This 6.8 mm platinum band cost $2,000.00 to transform to Ringlock.

Transforming a platinum or white gold ring can only be confirmed possible after
cutting and testing the metal to confirm its toughness, and none cracking quality.

If the metal proves to test bad cracking all bets are off.

Casting platinum in the market place has become the standard, as necessity, being the only hope to make a living for many craftsmen who work for the re-sellers (Store keepers) to cut cost, but the quality is inconsistent once again due to the nature of the material. One only has to look at all the postings of stones falling out, reports of rings cracking, and in general a big mess.

If your band is not thick enough (3.0 mm) It could be possible to fabricate a sleeve to install inside to thicken up your original band to the 3.0 mm required thickness to create a Ringlock.

Hinge center arm is channeled into
the opposite side for strength.

Soft satin finish was requested replacing the stippled look.

All bands are different from width to thickness, gold or platinum, so please send a picture of your ring in question so we may give you an idea of the cost, this is very labor intensive work.
