4 What We Do Scio manufactures diamond that is “real diamond” We employ a patent-protected Chemical Vapor Deposition (CVD) process that produces high-quality, single crystal diamond in a controlled laboratory setting Our diamond has chemical, physical and optical properties identical to mined diamonds Our manufacturing process enables us to produce high quality, high purity single-crystal diamond that is colorless, near colorless and fancy colored Our proprietary technology offers the flexibility to produce lab-grown diamond in size, color and quality combinations that are very rare in nature

7 Chemical Vapor Deposition (CVD) CVD is a process that is used to produce solid materials that are high-purity and high-performance in quality Well understood technology widely employed in the electronics and materials industries Most promising technology for producing low-cost and high quality diamond Scio patented CVD Single Crystal > 1mm thick Lowers stress in the crystal lattice which leads to greater strength and hardness for industrial use Produces low nitrogen Type IIa crystals (colorless / near colorless) – less than 3% of all mined diamonds qualify as Type IIa diamonds

8 CVD Diamond Growing Process Step 1 - Place diamond seeds on pedestal - depressurize chamber Step 2 - Inject starting gases into chamber - heat until electrons separate from nuclei, forming plasma Step 3 - Freed carbon precipitates out of plasma cloud and is deposited on wafer seeds Step 4 - Wafer seeds gradually become diamond crystals Step 5 - Remove diamond crystals. Slice and shape for use in commercial and gemstone applications Plasma Cloud Diamonds Pedestal

9 Scio CVD vs. HPHT/Microwave CVD SCIO designed reactors produce 7 to 10 times more diamond than the competitors Growth of Scio CVD can monitored and controlled during growth cycle Scio CVD has greater thickness potential due to single growth process Scio diamond surface area is significantly greater than HPHT Expected breakeven on capital investment per reactor is less than 18 months

10 Competitive Advantages Process to grow single crystal diamond of superior quality, strength and beauty Scalable process – can be expanded and replicated quickly and has a low return on capital threshold Highest rate of productive growth in the world Significant and growing intellectual property portfolio: 23 U.S. patents, 8 foreign patents 16 U.S. and 10 foreign patent applications in-process Create diamonds identical to mined diamond

11 Industrial Opportunities Current Applications - Precision Cutting Signed multi-million dollar deal for cutter blades with a South Korean tool manufacturer and been in business for 20+ years Potential to reach $350K monthly run rate Future Applications Semiconductor Substrate / Quantum Computing Scalpel – Laser Scalpel Molecular Resolution MRI Water Purification High Power Laser & Other Defense and Energy Applications

12 Industrial Growth Strategy Seeking to improve reactor yields through productivity enhancements: Currently – S3460 Technology (4 x 4 mm seeds) – 120 units of product in 7 days Spring 2013 – S3721 Technology (7 x 7 mm seeds) – 192 units of product in 7 days Fall 2013 – S31016 Technology (10 x 10 mm seeds) - 252 units of product in 7 days 2014 Opportunities: Mosaic Technology (flexible, larger-sized seeds) & 4” grower platform Expand current 10 reactors to 20 reactors $700k estimated cost per machine = $7M Sample economics of productivity enhancements and expansion: Technology Estimated Cutter Blade Production Estimated Annual Revenues Potential Gross Margin S3460 (4 x 4 mm seeds) ~42K ~ $4.2 ~ 35% S3721 (7 x 7 mm seeds) ~67K ~ $6.7 ~49% S31016 (10 x 10 mm seeds) ~88K ~ $8.8 ~ 54% 20 Reactors S31016 (10 x 10 mm seeds) ~176K ~ $17.6 ~ 58% 10 Reactors

13 Gemstone Opportunities Scio-created gemstones are real diamond Grown in a environmentally clean reactor instead of the earth Features of Scio-created diamond gemstones Perfection and Scalability – stones of same size and color Colorless and Pink diamond capability Environmentally friendly alternative to mined diamonds No “conflict diamond” concerns Gem market still in development stage “Recently in New York Laboratory, we tested a 2.16 ct. CVD lab-grown diamond from Scio Diamond Technology Corporation. This marquise-cut 2.16 ct diamond (13.42 x 6.73 x 3.94 mm) is the largest CVD synthetic diamond tested so far in GIA laboratories. Testing of a large CVD diamond with good gem quality like this one reconfirmed the rapid improvement of lab-grown technology. It is foreseeable that more CVD diamonds with better quality will get into the jewelry industry. “ GIA March 2013

14 Gemstone Growth Strategy Use current formulas for enhanced single crystal white and pinks Use proven formulas for pure colorless growth Prime sizes .50 – 1.25 carats – all fine grades Market – Distributors and major jewelers in the rough Revenue is expected to be accretive to commercial gross margins Sample economics of gemstone production with 10 growers: Gemstone run – 44 crystals – average size is 3.4 carats rough March 15, 2013 Stone Size (Carats) Estimate # of Stones Produced Estimated Revenues Potential Gross Margin 0.50 ~ 1,556 ~ $2,448 ~ 55% 0.75 ~ 916 ~ $2,676 ~ 65% 1.00 ~ 734 ~ $2,114 ~ 53% 1.25 ~ 498 ~ $1,810 ~ 55% ANNUAL TOTAL ~ 3,704 ~ $9,047 ~ 58%

15 Summary Continue development of sustainable commercial applications for mass production of high quality single crystal diamond targeting commercial and gemstone markets Anticipating mass production by advancing seed size from 4mm to 10mm by Fall 2013, an increase of 110% Seeking to double grow reactors to 20 Fixed corporate overhead per year $1.6M High gross margins and incremental revenue flows to bottom line Looking to exploit gemstone opportunities Long term objective is to be the world leader in the production of high-value added diamond material
