Lab Created Spinel
Lab Created Spinel replicates natural spinel's vivid red, pink, blue, and purple at a fraction of the price - the same MgAl₂O₄ crystal.
- The 'Black Prince's Ruby' in the British Imperial Crown Jewels - one of the world's most famous historical gems - is actually a large natural red spinel, not a ruby. The confusion lasted for centuries until modern gemological testing.
- Lab spinel was one of the most widely produced synthetic gemstones in history, used in mass-market jewelry for decades in the mid-20th century, often representing sapphire or aquamarine without clear consumer disclosure.
- Spinel is singly refractive (cubic crystal structure), unlike most colored gemstones. This means its facets don't show doubling under magnification - a unique optical property that distinguishes it from ruby, sapphire, emerald, and most other fine gems.
- Cobalt blue spinel - both natural and lab - gets its vivid electric blue from cobalt, the same element that colors cobalt blue glass and pottery.
- Natural Burmese spinel in fine quality reached $5,000 per carat at auction in the early 2020s as collectors recognized its historical significance and exceptional color - a dramatic appreciation from its long period of undervaluation.
- Those who want vivid red or pink gemstone jewelry without ruby's premium price or pink tourmaline's lower hardness
- August birthstone buyers who want the updated birthstone (spinel added in 2016) in lab form at an affordable price
- Collectors or enthusiasts who want to compare lab and natural spinel in the same range of colors
- Jewelry designers seeking perfectly matched spinels in specific colors - lab production allows color consistency
- Ethical buyers who want a gemstone with no mining footprint in the vivid-color gemstone range
- Collectors seeking the geological story and provenance of Burmese, Sri Lankan, or Tanzanian natural spinel
- Investors - lab spinel has minimal resale value compared to fine natural spinel which has appreciated significantly
- Those who specifically want the inclusions, character, and uniqueness of natural spinel crystals
What Is Lab Created Spinel?
Lab Created Spinel is magnesium aluminum oxide (MgAl₂O₄) grown in a laboratory - identical in chemistry and crystal structure to natural spinel. It has the same Mohs hardness of 8, the same refractive index of 1.718.
The same single refraction (spinel is isometric/cubic - it does not show doubling of facets under magnification, unlike many other colored stones). The color range available in lab spinel mirrors natural spinel: vivid red (from chromium), pink (dilute chromium), electric blue (iron and cobalt), lavender, purple, and orange.
Lab spinel has a distinctive history: it was among the most important early synthetic gemstones and was used in enormous quantities as a substitute for sapphire, ruby, and other colored stones in mass-market jewelry from the 1930s through the 1970s - often without disclosure.
This historical context means that many vintage pieces contain synthetic spinel identified only later when proper gemological testing became routine.
Natural spinel was itself historically confused with other stones - the famous 'Black Prince's Ruby' in the British Crown Jewels is actually a large natural spinel, not a ruby. The name 'spinel' derives from the Latin 'spina' (thorn) in reference to the stone's sharp crystal points.
Natural fine spinel from Burma (Myanmar) commands significant collector premiums today as its unique history and exceptional color are increasingly recognized.

Meaning and Symbolism
Spinel's meaning in crystal healing is closely related to its color - and since it comes in more colors than almost any other gemstone, its spiritual associations shift with the variety. Red spinel carries the same fire, vitality, and root-chakra associations as ruby, with slightly softer energy.
Pink spinel is associated with heart energy, love, and joy - a gentler version of ruby's passion. Blue spinel resonates with communication, truth, and clarity - aligned with sapphire's Throat chakra associations.
Lab spinel carries these color-based meanings fully. Crystal healing practitioners generally hold that a stone's energetic properties derive from its mineral composition and crystal structure - both of which are identical in lab and natural spinel.
The fact that lab spinel is singly refractive (cubic crystal system) gives it an energetic quality practitioners sometimes describe as 'straightforward' or 'uncomplicated' - clear directional energy without the harmonic complexity of doubly refractive stones.
Spinel's historical identity confusion - regularly mistaken for ruby and sapphire for centuries - adds a contemporary layer of meaning: it is a stone that was overlooked and undervalued while masquerading as something it was not, until its true nature was recognized.
Crystal healing practitioners who work with authenticity, self-recognition, and stepping out from under another's shadow sometimes use spinel specifically for this theme.
Historical Timeline
Healing Tradition
Emotional
Lab spinel's emotional associations are color-dependent. Red and pink lab spinel are said to work with vitality, passion, and the courage to engage life fully - stimulating the inner fire that drives authentic action and self-expression.
Blue lab spinel is associated with calming overactive emotional states, bringing cool clarity to situations where heat has made clear thinking difficult. Purple and lavender spinel bridges heart and mind, traditionally associated with the integration of feeling and thought into wise response.
Across all colors, practitioners describe spinel as having a 'clean' energetic quality - straightforward, direct, and unencumbered, reflecting the cubic crystal structure's geometric simplicity.
Spiritual
In crystal healing tradition, spinel is associated with renewal and revitalization - the idea that it clears the energetic field and restores original vitality. Many practitioners use it in sessions focused on clearing accumulated energetic debris, restoring clarity to an energy field that has become congested or sluggish.
Red spinel specifically is linked to Kundalini energy - the spiritual vitality that rises from the Root chakra upward through the body's energetic centers. Blue spinel activates the upper centers for spiritual clarity.
The singly refractive optical property is sometimes interpreted as focused, undivided energy - a stone that goes straight to its target without dispersal.
Physical
Crystal healing tradition associates spinel's different colors with different physical systems - red and pink with the circulatory system and physical vitality, blue with the respiratory and nervous systems, and all varieties with the adrenal glands and the body's capacity for sustained energetic output.
The stone's associations with renewal make it a traditional recommendation for those recovering from depletion, illness, or extended periods of overwork. These are traditional metaphysical associations and complement rather than replace qualified medical care.
Zodiac, Birthstone and Gifts
Spinel's zodiac connections shift with color but the fire-sign resonance is strongest overall. Leo, the sign of creative sovereignty and the desire to shine, resonates with red and orange spinel's vitality and radiance - a stone that expresses Leo's inherent generosity of spirit and warmth.
Aries, the first fire sign and the initiator, connects with spinel's clean, direct energy - no complexity, just pure vital drive in the direction of the stone's color.
Scorpio, whose August association overlaps with spinel's new birthstone status, finds in spinel a stone that matches its intensity without the demanding depth of other Scorpio-associated stones - direct, powerful, and honest.
Care and Cleansing
Lab spinel is chemically stable and hard (Mohs 8) - all standard cleansing methods are safe. Running water, salt water (brief), moonlight, sunlight, sound, smoke, and selenite are all effective. Ultrasonic cleaners are safe for lab spinel in secure settings.
Choose the cleansing method that resonates with the stone's color: fire-adjacent methods (sunlight, candle smoke) for red and pink; water and moonlight for blue and lavender. This is intuitive rather than technically necessary - all methods work for all colors - but the color-matched ritual adds meaning and intention to the practice.
- DO wear freely - Mohs 8 hardness is excellent for all jewelry types including rings.
- DO clean with warm water, mild soap, and a soft brush or use an ultrasonic cleaner.
- DO disclose as lab created when selling or insuring - required by FTC regulations.
- DO NOT assume resale value - lab spinel has minimal market value compared to fine natural spinel.
- Note: Lab spinel is singly refractive - facets will not show doubling under magnification, which is a natural property, not a quality defect.
- Note: Some lab spinel shows Chelsea filter reaction (glows orange under a Chelsea filter) - useful for identification, not a defect.
- DO have significant jewelry pieces appraised and insured at replacement cost, which is based on the setting and labor rather than the stone.
Real vs Fake
Lab spinel is genuine MgAl₂O₄ spinel - not a fake in any meaningful sense. The relevant question is lab vs natural origin. Under magnification, Verneuil lab spinel shows curved growth striations and may have gas bubbles - both absent in natural spinel, which shows irregular natural inclusions.
Lab spinel is also typically cleaner than natural spinel of comparable color.
The single refraction is helpful for distinguishing spinel from commonly confused stones: ruby and sapphire are doubly refractive (corundum), tourmaline is strongly doubly refractive, and garnet is singly refractive. A polariscope confirms spinel's single refraction.
Specific gravity (approximately 3.60) and refractive index (1.718 fixed) help confirm identification as spinel vs other similar-looking materials.
Historically, undisclosed synthetic spinel was used extensively in mass-market jewelry to represent other stones - many vintage pieces contain lab spinel labeled as aquamarine, sapphire, or other gems.
If you inherit or purchase vintage jewelry with an unusually uniformly colored 'aquamarine' or 'sapphire,' gemological testing may reveal it is synthetic spinel - not a scandal, but an interesting historical artifact of mid-20th century trade practices.
Lab Created Spinel Jewelry & Gifts
Lab Created Spinel is among the most affordable quality lab gemstones available. Small faceted stones (under 1 carat) start from $5 to $15. Good quality 1 to 3 carat lab spinels with vivid color run $15 to $50 per stone. Premium quality in larger sizes rarely exceeds $100 for most colors.
Red and cobalt blue tend to be most sought and may command slight premiums.
Color quality is the primary purchase consideration - look for vivid, clean color without gray or brown modifiers. Red lab spinel should be a clean, vivid red approaching ruby red without orange overtones. Blue should be a clean cornflower to cobalt blue without grayish modifier.
Pink should be clean pink without salmon or peach tones.
Lab spinel is widely available from gemstone wholesalers, lab-created gemstone retailers, and online platforms. Reputable sellers will clearly label it as synthetic or lab created spinel.
Given its historical use as an undisclosed substitute, be aware that some sellers may not know what they are selling - if a price and appearance seem inconsistent with natural gemstone market pricing, ask about origin.
