1.08ct Natural Montana Sapphire Platinum Eternity Band | Carbon & Gold

Subtle colour variation defines this Montana sapphire eternity band, featuring 1.08 total carats of round sapphires arranged in a continuous gradient and set in platinum.

Measuring approximately 2.50 mm each, the Montana sapphires transition through cool shades of teal, blue-green and forest green. Their shifting colour creates a natural sense of movement around the entire ring, while platinum’s cool white tone allows every subtle variation to remain clearly visible.

Weighing approximately 3.80 grams, the band combines a refined profile with the reassuring presence of platinum. Its understated scale makes it equally suited to wearing alone, pairing with an engagement ring or adding a quiet gradient of colour to a curated stack.

Care & Wear

Sapphire measures 9 on the Mohs hardness scale and is highly suitable for everyday jewellery. Platinum is dense and durable, but it will gradually develop a soft surface patina with regular wear. Because gemstones circle the entire band, remove the ring before lifting, exercise or hands-on work. Clean with lukewarm water, mild soap and a soft brush, and have the prongs inspected periodically. Professional polishing can restore a brighter platinum finish if desired.
