Oval pinkish Ruby & Side Diamonds Ring

Diamond is crystalline carbon: a single element arranged in a tightly bonded crystal structure. It ranks 10 on the Mohs scale, giving it exceptional resistance to scratching. Hardness is not the same as toughness, however; like any gemstone, diamond can chip or cleave if struck sharply in a vulnerable direction.

Ruby is the red variety of corundum. Chromium is the trace element responsible for its red color. It ranks 9 on the Mohs scale and combines high hardness with excellent toughness and no cleavage, making it well suited to jewelry.

Color is the leading quality factor. Fine ruby ranges from pure, vibrant red to slightly purplish red. Treatments can affect care requirements, so cleaning advice should follow the stone’s verified treatment status.

White gold is a family of gold alloys rather than a single formula. Pure gold is mixed with white-colored metals to produce a paler color and improve working properties. Many pieces are rhodium plated to create a brighter, harder surface.

Karatage describes gold purity. Fourteen-karat gold contains about 58.3% gold and is commonly marked 585; the remaining alloy varies by formulation. A product’s exact alloy and surface treatment should be verified separately when relevant.
