ARE LAB GROWN DIAMONDS WORTH IT?
THE HONEST ANSWER
Lab-grown diamonds are worth it if you want a real diamond at a lower price. Not worth it if resale value matters to you. The answer depends on what you value most.
This guide presents facts. No sales pitch. You decide what matters for your situation.
WHAT THEY ARE
Lab-grown diamonds are real diamonds. Chemically, physically, and optically identical to mined diamonds. The FTC confirms this. Not diamond simulants like cubic zirconia.
Created in controlled environments using CVD or HPHT methods. Takes weeks to months instead of millions of years. Same carbon structure. Same hardness of 10 on Mohs scale.
Graded by the same standards. GIA and other labs certify them using the 4 Cs. You cannot tell them apart with your eyes. Gemologists need specialized equipment.
THE PRICE ADVANTAGE
Lab diamonds cost 30-60% less than equivalent mined diamonds. This is the main appeal.
WHAT THIS MEANS
A $5,000 budget buys a larger or higher-quality lab diamond than a mined one. Get a 2-carat lab diamond for the price of a 1-carat mined stone. Or get better color and clarity at the same size.
WHY THEY COST LESS
No mining operations needed. No exploration or excavation costs. Controlled production means predictable supply. The price reflects production cost, not rarity.
PRICE TRENDS
Lab diamond prices have dropped as production improved. This trend may continue. Good for buyers. Bad for resale value. Your purchase will not appreciate.
RESALE REALITY
Lab diamonds have poor resale value. This is the biggest drawback. Be honest about this reality.
THE NUMBERS
Most lab diamonds resell for far less than purchase price. Expect to recover 10-30% at best. Some dealers will not buy them back at all. The market is still developing.
WHY THIS HAPPENS
Supply grows as production scales up. No natural scarcity to maintain value. New buyers prefer purchasing at current market prices. Secondary market has not matured yet.
MINED DIAMONDS TOO
Natural diamonds also lose value after purchase. Most mined diamonds are not investments either. The difference is degree, not kind. Neither holds value like gold.
IF THIS MATTERS
If you might sell or trade the diamond later, lab-grown is not the best choice. Natural diamonds retain more value. But if you plan to keep it forever, resale value does not matter.
QUALITY VARIES
Lab diamonds range from excellent to poor quality. Just like mined diamonds. The same grading standards apply. Check certificates carefully.
CVD and HPHT methods produce different results. Some show color tints. Some have inclusions. Use the 4 Cs to evaluate each stone individually. Do not assume all lab diamonds are flawless.
Buy from reputable sources with proper certifications. Avoid stones without GIA or IGI reports. The lower price does not guarantee good value if quality is poor.
ENVIRONMENTAL IMPACT
The environmental story is complex. Lab diamonds are better than mining, but not impact-free.
ENERGY USE
Lab diamonds require substantial electricity. HPHT uses extreme heat. CVD needs energy equivalent to powering a home for a month per carat. Where this energy comes from matters.
COMPARED TO MINING
Mining uses about twice the energy per carat. Uses seven times more water. Creates land disruption and ecosystem damage. Lab production has smaller physical footprint.
THE HONEST TAKE
Lab diamonds are the more environmentally sound choice between the two options. Neither is perfectly green. If environmental impact is your priority, consider other gemstones entirely.
WHO SHOULD BUY THEM
GOOD FIT IF YOU
- • Want a larger diamond on your budget
- • Plan to keep the ring forever
- • Value what the diamond represents, not its resale potential
- • Prefer to avoid mining industry concerns
- • Want better color or clarity for less money
- • Care about the diamond being real, not rare
POOR FIT IF YOU
- • Might upgrade or sell the stone later
- • Value rarity and natural formation
- • Want traditional heirloom appeal
- • Care about resale value over initial cost
- • Prefer stones with established secondary markets
COMMON MISCONCEPTIONS
"Lab diamonds are fake"
False. Lab diamonds are real diamonds with the same chemical structure as mined ones. The FTC requires sellers to call them diamonds. Only the origin differs.
"They cannot be appraised"
False. Grading labs certify lab diamonds using standard methods. Appraisals reflect current market value. The issue is resale price, not appraisal ability.
"They look different"
False. You cannot tell lab from mined diamonds with your eyes. Same sparkle, same appearance. Gemologists need specialized equipment to detect trace elements that identify the origin.
"They are completely eco-friendly"
Misleading. Lab diamonds use significant energy. Better than mining, but not zero-impact. The environmental benefit depends on energy sources used in production.
"Lower price means lower quality"
False. Lower price reflects production cost and market supply. Quality varies by individual stone, not origin. A well-graded lab diamond matches the quality of an equivalent mined stone.
