Sapphire engagement rings are known for their strength

2. Sapphire engagement rings are available in many different colours. Sapphire offers a wide selection of colours and each particular color comes in numerous shades. Colours range between dark purple, to light brown, to deep orange. Blue is also the hottest color choice for sapphire engagement rings, which can change color with the light. 3. Sapphire engagement rings are less certain to chip than diamonds. Though not as hard and as tough as diamond, sapphire is less sure to chip than diamonds. This is as diamonds can be damaged when struck sharply in a certain direction. Therefore , sapphire engagement rings are the wiser choice as engagement rings are susceptible to chips and scratches. 4. Sapphire engagement rings can be more durable than ruby engagement rings. Though sapphire and ruby are both varieties of the mineral corundum and both have a toughness of 9, rubies aren't as durable as other sapphires. Some are cut into faceted shapes, while others are cut in a domed shape. There are conventional rounded rectangle and oval shapes, triangle, pear shape and the classic marquise cut. 6. Tips on buying sapphire engagement rings : When purchasing a sapphire engagement ring, inspect the stone by natural daylight. Check if the stone show a uniform color. 2. Select a sapphire engagement ring with only one to five carats sapphire gemstone as bigger sapphires are far more susceptible to damages. 3. Choose the one with a safer setting, like bezel. Ensure that it fits well and feel comfortable on the finger. Costs can change from relatively inexpensive to the dearer range.
