corundum in every color<\/h3>\n

Sapphire<\/h1>\n

The sapphire is one of the most beloved gemstones of all time: a hard, luminous corundum that we associate with deep blue, but which in nature appears in almost every color. In Giverso’s sapphire jewelry, blue sits alongside pink, yellow, orange and fuchsia, in tennis bracelets, chokers, wedding bands, rings and earrings.<\/p>\n[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row et_full_width=”true” et_row_padding=”true” css=”.vc_custom_1588128887000{padding-top: 60px !important;padding-bottom: 60px !important;}”][vc_column][vc_row_inner content_placement=”middle” el_class=”align-center”][vc_column_inner el_class=”small-order-2 medium-order-1″ offset=”vc_col-md-7″ css=”.vc_custom_1766576943890{padding-top: 40px !important;}”][vc_column_text css=””]\n

Not just blue: the colors of sapphire<\/h2>\n

Chemically, sapphire is corundum, an aluminum oxide: ruby is the same mineral and takes that name only when it is red. All the other color varieties are called sapphires. The difference comes from tiny traces of other elements: iron and titanium give blue, chromium gives pink, iron gives yellow. That is why sapphires come in blue, pink, yellow, orange and fuchsia, as well as the rare shades between orange and pink known as padparadscha.

Hardness and durability<\/h3>\n

At 9 on the Mohs scale, sapphire is second only to diamond in hardness. It resists scratches and everyday wear, which makes it one of the best stones for rings and wedding bands that are worn every day.

Natural or heat-treated?<\/h3>\n[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner et_column_align=”align-center” equal_height=”yes” el_class=”align-center”][vc_column_inner offset=”vc_col-lg-4″][vc_column_text css=””]\nMost sapphires on the market are heat-treated: heat improves the color and clarity of the rough stone. It is a widespread practice, recognized in the trade for a long time, as long as it is disclosed.
\n[\/vc_column_text][\/vc_column_inner][vc_column_inner offset=”vc_col-lg-4″][vc_column_text css=””]\nThe treatment does not change the nature of the stone, which remains a natural sapphire. Untreated sapphires are rarer and sought after by collectors. If you have any questions about a particular piece, contact us or visit the store.
