A bracelet takes more knocks than a necklace, so the setting matters, and bezels protect each stone's edges, so we favor them. Sapphire at 9 on the Mohs hardness scale handles daily wear, emerald at 7.5 to 8 wants ordinary caution, and kyanite is the gentlest stone here and comes off before the gardening gloves go on. Warm water, mild soap, and a soft cloth for all of them; no ultrasonic or steam.
