Lapis lazuli was also used to make dyes, especially a rich blue hue known as ultramarine. This paint was quite expensive, seeing as it was created using the finest stones. A lot of artists creating pictures of the Madonna used paint created from lapis lazuli.
▶ After each wear, wipe your jewelry with a soft cotton cloth (preferably the one that came with the jewels) after you remove it. This action rids the piece of any oil residues from your skin, makeup, perfume, and other dirt.
▶ If you're pressed to store your lapis jewelry with other pieces, wrap it in velvet before you store it. Doing so will protect the stones from friction, scratching, and other means of wear and tear.
▶ Chemicals, acids, and heating can all cause irreparable damage to this gemstone and should be avoided. Never soak these pieces in hot water. Constant exposure to heat or sunlight can result in fading.
