Natural Characteristics
Each natural gemstone is unique in its color, clarity, inclusions, patterns, proportions, and cut. Natural inclusions, color zoning, or slight variations are part of the gemstone’s individual character and are not necessarily considered defects.
Treatments & Certification
Some gemstones may undergo commonly accepted treatments to enhance their appearance or stability. Any known treatment and available laboratory certification will be disclosed before approval.
Visual Representation

Laboratory Certification
MRSAE may provide an independent laboratory certificate for selected gemstones, depending on the stone’s type, size, value, and eligibility for testing. Not all gemstones include certification by default. Any available certificate, applicable laboratory, timeline, and additional cost will be confirmed before approval.
Gemstone Guide
Diamond
Mohs hardness: 10
Diamond is the hardest natural gemstone and is highly resistant to scratching, making it suitable for everyday jewelry. However, strong impact can still cause chipping, especially around sharp edges.
Sapphire
Mohs hardness: 9
Sapphire is a durable gemstone suitable for everyday wear. It is available in many colors, including blue, pink, yellow, green, and white. Natural inclusions and color zoning may be present.
Ruby
Mohs hardness: 9
Ruby belongs to the same mineral family as sapphire and is known for its red color. Its excellent hardness makes it suitable for frequently worn jewelry. Natural inclusions are common and may add to the stone’s individual character.
Emerald
Mohs hardness: 7.5–8
Emerald is admired for its rich green color and naturally occurring inclusions, often referred to as its jardin. Although relatively hard, emeralds can be more fragile and require careful handling.
Spinel
Mohs hardness: 8
Spinel is a durable natural gemstone available in red, pink, purple, blue, grey, and other colors. It offers excellent brilliance and is generally suitable for regular wear.
Aquamarine
Mohs hardness: 7.5–8
Aquamarine is known for its soft blue to blue-green color. It is suitable for regular wear but should be protected from strong impact and sudden temperature changes.
Tourmaline
Mohs hardness: 7–7.5
Tourmaline is available in a wide range of colors, including pink, green, blue, and bi-color varieties. It should be worn with reasonable care, particularly in rings.
Garnet
Mohs hardness: 6.5–7.5
Garnet is available in more colors than its familiar deep red, including green, orange, pink, and purple. Its durability varies by variety, so protective settings may be recommended.
Topaz
Mohs hardness: 8
Topaz is resistant to scratching but has natural cleavage, meaning it may chip or split under strong impact. It is available in blue, yellow, pink, and other colors.
Amethyst
Mohs hardness: 7
Amethyst is a purple variety of quartz. It is suitable for occasional or regular wear with proper care, but prolonged exposure to strong heat or sunlight should be avoided.
Citrine
Mohs hardness: 7
Citrine is a yellow to orange variety of quartz. It offers good durability for jewelry but should still be protected from impact, extreme heat, and harsh chemicals.
Zircon
Mohs hardness: 6–7.5
Natural zircon is known for its strong brilliance and fire. It is different from cubic zirconia. Its facet edges may wear over time, so it is best worn with additional care.
Opal
Mohs hardness: 5.5–6.5
Opal is valued for its unique play of color. It is relatively delicate and sensitive to impact, heat, dryness, and sudden temperature changes. Protective settings are recommended.
Pearl
Mohs hardness: 2.5–4.5
Pearls are organic gemstones with a naturally soft surface. They should be protected from perfume, cosmetics, chemicals, moisture, and abrasion. Pearls are best worn after applying beauty products and wiped gently after use.
General Care Note
Gemstone suitability depends not only on Mohs hardness, but also on toughness, internal structure, cut, setting, and daily use. MRSAE may recommend a protective setting or alternative gemstone depending on the design and intended wear.
